Formaldehyde is a colorless, pungent gas; if clothing contains formaldehyde, it emits a strong odor.</p> <p><strong>Dealing with Formaldehyde in Clothing:</strong></p> <p>Cleaning and airing garments is an effective way to reduce formaldehyde content. Newly purchased clothes should be soaked and washed to allow the formaldehyde to dissolve in water. After washing, hanging the clothes in a sunny area facilitates complete evaporation of formaldehyde while also providing disinfection and eliminating harmful substances such as bacteria and mites.</p> <p><strong>Formaldehyde Sensors for Detection:</strong></p> <p>Given the necessity of formaldehyde monitoring in the textile printing industry, formaldehyde sensors can be employed to measure formaldehyde concentrations. Here are two recommended formaldehyde sensors:</p> <p><strong>NE-HCHO-S:</strong></p> <p>The NE-HCHO-S electrochemical formaldehyde sensor from Japan’s NEMOTO offers high sensitivity and reliability. It is suitable for detecting and measuring residual formaldehyde concentrations in wood building materials or post-sterilization. The sensor is compatible with various devices.</p> <ul><li>Detection gas: Formaldehyde</li> <li>Detection range: 0 ~ 10 ppm</li> <li>Maximum overload: 50 ppm</li> <li>Output signal: 600 ± 150 nA/ppm</li> <li>Repeatability: ± 5%</li> <li>Typical baseline range (in pure air): < ± 0.05 ppm</li> <li>Typical response time (T90): < 120 sec. (HCHO: 1 ppm)</li> <li>Baseline change (0 ~ 40°C): < 0.2 ppm</li> <li>Expected lifespan: Over 2 years</li></ul> <p><strong>TB600C-HCHO-100:</strong></p> <p>The TB600C-HCHO-100 formaldehyde sensor from Germany’s EC Sense offers high accuracy, long lifespan, fast response and recovery, zero drift, and plug-and-play functionality. It features excellent precision, repeatability, linearity, consistency, and resistance to electromagnetic interference.</p> <ul><li>Detection principle: German EC Sense solid-state polymer electrochemical detection technology</li> <li>Detection gas: Formaldehyde</li> <li>Detection range: 0 ~ 100 ppm; Resolution: 0.1 ppm</li> <li>Lowest detection limit: 1 ppm</li> <li>Stable time (typical): < 120 seconds (storage in clean air for the first time, powered on)</li> <li>Response time (typical): < 3 seconds (T50: < 40 seconds, T90: < 80 seconds, T100: < 180 seconds)</li> <li>Zero recovery time (typical): < 40 seconds for 50 ppm (to below 1 ppm, in a ventilated relatively clean environment)</li> <li>Calibration substance: Formaldehyde gas</li> <li>Expected sensor lifespan: Over 3 years in a relatively clean air environment</li> <li>Output signal: Standard 3.3V level UART digital signal</li></ul> <p><strong>Conclusion:</strong></p> <p>Given the associated health risks, formaldehyde monitoring is crucial in the textile printing industry. Using formaldehyde sensors allows for accurate detection of formaldehyde concentrations. The NE-HCHO-S sensor from NEMOTO and the TB600C-HCHO-100 sensor from EC Sense are recommended options for reliable formaldehyde detection. Employing these sensors will help ensure compliance with safety regulations and promote healthier and safer garments for consumers.</p>]]></content:encoded> </item> <item> <title>Gas Flow Detection Sensor For Vacuum Packaging Machines</title> <link>https://packprintmachine.com/gas-flow-detection-sensor-for-vacuum-packaging-machines/</link> <dc:creator><![CDATA[Packprint Machine]]></dc:creator> <pubDate>Sun, 16 Jul 2023 14:48:46 +0000</pubDate> <category><![CDATA[Technology]]></category> <category><![CDATA[Business]]></category> <category><![CDATA[Education]]></category> <guid isPermaLink="false">https://packprintmachine.com/?p=80</guid> <description><![CDATA[Vacuum technology is an integral part of modern scientific and technological advancements, widely employed in various sectors of the economy.

One prominent vacuum technology application is in the food industry, where vacuum packaging machines are utilized. By removing air from the packaging, vacuum sealing helps preserve food by inhibiting oxidation and extending its shelf life. In this blog, we will explore the role of the gas flow sensor FS1015 in gas flow detection within vacuum packaging machines.</p> <p><strong>Gas Flow Detection in Vacuum Packaging Machines:</strong><strong></strong></p> <p>Vacuum packaging machines are designed to automatically extract air from packaging bags, reaching the desired vacuum level before completing the sealing process. Additionally, these machines can introduce gases such as nitrogen or other gas mixtures before sealing the package. Monitoring gas flow during the vacuum process requires the inclusion of a flow control valve. In a vacuum state, the gas flow through the control valve is primarily determined by four variables: upstream and downstream pressure, gas flow temperature, and the pressure differential across the valve.</p> <p><strong>Characteristics of Gas Flow Measurement in Vacuum Conditions:</strong></p> <p><strong>Low flow density:</strong> The low flow density in vacuum conditions limits the effectiveness of commonly used flow measurement devices such as vortex flow meters or ultrasonic flow meters. Vortex flow meters generate insufficient airflow thrust, while ultrasonic flow meters face impedance-matching difficulties.</p> <p><strong>Minimal pressure loss:</strong> Avoiding significant pressure losses when installing flow meters on vacuum pipelines is essential. Increased resistance due to the flow meter’s installation on the vacuum pipeline leads to higher power consumption, hindering energy efficiency. Consequently, orifice plate flow meters, turbine flow meters, and positive displacement flow meters are not suitable choices.</p> <p><strong>Leakage detection challenges:</strong> Detecting leaks becomes challenging when flow meters are installed on negative-pressure pipelines. Undetected leaks not only waste power but also compromise the internal gas environment.</p> <p><strong>Introducing the FS1015 Gas Mass Flow Sensor by Siargo:</strong></p> <p>To address the gas flow detection requirements in vacuum packaging machines, we recommend the FS1015CL gas mass flow sensor by Siargo, a renowned manufacturer based in the United States.

Vacuum packaging machines are widely used for processed foods because they require large-scale production with significant raw materials, necessitating an extended shelf life. Methods such as high-temperature cooking are often used to extend shelf life, and vacuum packaging is essential in this process. By removing oxygen from the packaging bag and the food cells, vacuum packaging takes advantage of the fact that the growth of most microorganisms, such as molds and yeasts, requires oxygen, effectively depriving them of their “habitat.”</p> <p>Vacuum packaging machines primarily work by extracting air from the vacuum bags to prolong packaged foods’ shelf life and storage effectiveness. Different types of packaging require different levels of vacuum. For products that demand strict air control, high-power vacuum pumps are used to eliminate air.</p> <p><strong>The Importance of Vacuum Levels:</strong><strong></strong></p> <p>However, sometimes vacuum-sealed food products may experience “bag inflation” due to insufficient vacuum levels. Inexpensive vacuum packaging machines often fail to meet the required vacuum levels. Commercial vacuum packaging machines typically achieve vacuum levels ranging from 600-50 Pa, with accompanying vacuum pump prices varying from a few tens to several hundred thousand yuan. Naturally, the shelf life of products packaged by a small-scale vacuum packaging machine costing a few thousand yuan differs from that of a large-scale machine costing hundreds of thousands.</p> <p>The vacuum pump used determines the vacuum level of a vacuum packaging machine. Currently, there are three types of vacuum pumps in the market: domestic, joint-venture, and imported. While these pumps are functionally similar, they differ significantly in terms of extreme vacuum levels, which is particularly important for food enterprises as different foods have varying vacuum requirements.</p> <p><strong>Monitoring Vacuum Levels with High-Response Thermal Conductivity Gas Sensors:</strong><strong></strong></p> <p>When evaluating the vacuum level of a vacuum packaging machine, high-response thermal conductivity gas sensors (thermal conductivity gas sensors) are commonly used. These sensors can monitor vacuum level changes during the vacuuming process of packaging food, ensuring the integrity of food packaging. </p> <p>The MTCS2601 thermal conductivity gas sensor, manufactured by Neroxis in Switzerland and available through GONGCAI.com, is based on the Pirani principle for vacuum level detection. It is a low-power, long-life, and maintenance-free product suitable for primary pressure control in harsh environments, where power consumption, size constraints, gas leakage, moisture intrusion, or infiltration are critical.</p> <p>The MTCS2601 sensor consists of four Ni-Pt resistors based on MEMS technology, forming a micro-mechanical thermal conductivity sensor. This sensor is installed in a small SMD package and combines low-power CMOS standard integrated circuits, making it ideal for leak detection in OEC manufacturing or vacuum-level detection based on the Pirani principle, where ultra-low power consumption, long lifespan, and maintenance-free operation are required. It is suitable for primary pressure control in harsh environments with power and size limitations or in the presence of gas leakage, moisture, or intrusion.</p> <p><strong>Key Features of the MTCS2601 Thermal Conductivity Gas Sensor:</strong></p> <ul><li>Measurement range: 0.0001~1000 mbar with excellent repeatability.</li> <li>The silicon chip includes heating resistors and excellent temperature compensation.</li> <li>Ultra-small gas volume (<0.1 cm3) occupied by the sensor.</li> <li>Stable and long mean time between failures (MTBF) (>30,000 hours) based on physical impedance induction.</li> <li>Ultra-low power consumption (<6 mW) due to the use of MEMS sensors with small heating elements.</li> <li>Ultra-fast response time (<50 ms).</li> <li>Insensitive to the installation position.</li> <li>Compatible with a simple constant temperature circuit.</li> <li>It can be used in environments with interfering gases.</li></ul> <p><strong>Applications of the MTCS2601 Thermal Conductivity Gas Sensor:</strong></p> <ul><li>Monitoring H2, CH4, CO2, and LPG gases in indoor and outdoor air.</li> <li>Process control in the food industry (e.g., measuring CO2 in carbonated beverages).</li> <li>Hydrogen sensors for fuel cells.</li> <li>Measuring CH4 in biogas plants.</li> <li>Detecting refrigerant gases (CFCs, PFCs, HFCs, etc.).</li> <li>Electronic products (e.g., helium control in diving equipment).</li> <li>Respiratory system monitoring (medical applications).</li> <li>Leak control in closed systems operating under inert gases (e.g., strain gauges, hard disk quality control).</li> <li>Vacuum Level/Pressure Measurement Sensor Applications:</li> <li>Fixed and portable analytical instruments.</li> <li>Leak detection and primary vacuum control in closed systems (e.g., kinetic energy storage systems).</li> <li>Vacuum equipment used in the semiconductor industry.</li> <li>Food industry (vacuum packaging machines).</li></ul> <p>Generally, Pirani micro-sensors occupy a small area and can be integrated into any major vacuum system that requires their control (e.g., seal control, potential corrosion, or accidental opening).</p> <p><strong>Recommended Operating Conditions for the MTCS2601 Thermal Conductivity Gas Sensor:</strong><strong></strong></p> <p>The MGSM2601 has four separate resistors: Rm1 and Rm2 on the thin film for heating/measurement and Rt1 and Rt2 on the “cold part” of the sensor for temperature measurement and compensation. A constant overheating mode is recommended for pressure measurements in a low vacuum. This is an excellent method to avoid sensor damage, as the pressure-induced change in thermal conductivity within a certain range depends on the application’s rapidity.</p> <p>Storage Conditions:</p> <ul><li>Temperature: -40~100°C</li> <li>Humidity: 0~100%RH, non-condensing</li> <li>Mechanical Pressure Testing:</li> <li>Gravity acceleration: 1000g, 0.2mS, semi-sine wave</li> <li>Vibration: 10g RMS, sine wave: 20~2000Hz</li></ul> <p><strong>Conclusion:</strong></p> <p>High-response thermal conductivity gas sensors, such as the MTCS2601, are crucial components in monitoring vacuum levels during the vacuum packaging process in the food industry. Their ability to detect changes in vacuum levels rapidly ensures the quality and integrity of food packaging. With its outstanding features, including a wide measurement range, excellent repeatability, low power consumption, and fast response time, the MTCS2601 is well-suited for various applications, ranging from gas concentration measurements to vacuum level/pressure measurements. By utilizing advanced sensor technology, the food industry can achieve better control over the packaging process, extend shelf life, and ensure the safety and quality of packaged food products.</p>]]></content:encoded> </item> <item> <title>How to Control VOC Emissions in the Printing and Packaging Industry</title> <link>https://packprintmachine.com/how-to-control-voc-emissions-in-printing-ackaging/</link> <dc:creator><![CDATA[Packprint Machine]]></dc:creator> <pubDate>Sun, 16 Jul 2023 10:52:49 +0000</pubDate> <category><![CDATA[News]]></category> <category><![CDATA[Technology]]></category> <guid isPermaLink="false">https://packprintmachine.com/?p=76</guid> <description><![CDATA[The printing and packaging industry is crucial in product presentation and brand communication.

However, it is also associated with the emission of volatile organic compounds (VOCs), which can have detrimental effects on air quality and human health. In this blog, we will explore ways to control VOC emissions in the production processes of the printing and packaging industry.</p> <p><strong>Source Control:</strong></p> <p>One effective approach to reducing VOC emissions is through source control. This involves using environmentally friendly inks, adhesives, and cleaning agents with low or zero VOC content. Starting with low-VOC raw materials, the overall VOC emissions can be significantly reduced from the beginning of the process.</p> <p><strong>Process Management:</strong></p> <p>Process management focuses on optimizing and regulating production processes. Drying is an essential step in packaging printing and often contributes to significant VOC emissions. By promoting the use of optimized drying equipment and control systems and implementing curing technologies, VOC emissions can be effectively controlled during the drying process.</p> <p><strong>End-of-Pipe Treatment:</strong></p> <p>End-of-pipe treatment refers to the treatment of VOC emissions at the end of the production process. In the packaging printing industry, there are two primary categories of organic waste gas treatment technologies: solvent recovery and destruction methods.</p> <p>Solvent recovery techniques aim to separate and recover VOCs from the exhaust gas. These methods include adsorption-condensation recovery and absorption-dissolution techniques. They are suitable for processes that involve a high volume of organic solvents and inks with high VOC concentrations.</p> <p>Destruction methods, on the other hand, focus on decomposing VOCs. Common destruction technologies include thermal oxidation (catalytic combustion, regenerative oxidation) and plasma oxidation. These methods are suitable for treating large volumes of exhaust gas with low VOC concentrations.</p> <p><strong>Adsorption Method:</strong></p> <p>The adsorption method is a commonly used technique to remove VOCs. It relies on the interaction between VOC components in the gas mixture and porous solid adsorbents. When the gas contacts the adsorbent surface, the VOCs are adsorbed, separating them from the gas and purifying it. The adsorption process can be carried out in fixed-bed, moving-bed, or fluidized-bed adsorbers.</p> <p>Adsorption methods are generally effective for treating medium to low concentrations of gaseous pollutants. The adsorption efficiency depends on factors such as the properties of the adsorbent, the types of VOCs present, and operating parameters like temperature, humidity, and pressure. </p> <p>Activated carbon is a commonly used adsorbent due to its large surface area, adsorption structure, selectivity, and catalytic properties. It plays a significant role in VOC treatment, especially for VOC control. Overall, adsorption techniques are cost-effective, efficient, and flexible. However, they may incur high operating costs and potentially generate secondary pollution.</p> <p><strong>Conclusion:</strong></p> <p>Controlling VOC emissions in the printing and packaging industry is crucial for environmental sustainability and human health. The industry can effectively reduce VOC emissions by implementing the above ways and utilizing end-of-pipe treatment technologies. Businesses must prioritize environmental responsibility and adopt these strategies to contribute to a cleaner and healthier future.</p>]]></content:encoded> </item> <item> <title>Carbon Dioxide Sensors for Food-Modified Atmosphere Packaging</title> <link>https://packprintmachine.com/carbon-dioxide-sensors-for-food-modified-atmosphere-packaging/</link> <dc:creator><![CDATA[Packprint Machine]]></dc:creator> <pubDate>Sun, 16 Jul 2023 10:44:15 +0000</pubDate> <category><![CDATA[Technology]]></category> <guid isPermaLink="false">https://packprintmachine.com/?p=73</guid> <description><![CDATA[Modified Atmosphere Packaging (MAP) technology utilizes a blend of gases, such as oxygen (O2), nitrogen (N2), and carbon dioxide (CO2), to replace the air surrounding packaged food items.

By leveraging the packaging materials’ permeability and gas barrier properties, MAP maintains the food in an optimal gas environment, inhibiting spoilage and extending shelf life. </p> <p>This technique has widely adopted across various food categories, including fresh fruits, vegetables, raw and cooked meat products, seafood, dry goods, snacks, and convenience foods. MAP is prevalent in Western and Northern Europe, with various fresh fish available in supermarkets. MAP fresh fish accounts for 10% of all MAP perishable food retail in the UK, demonstrating its global leadership in applying MAP for raw meat and meat products.</p> <p><strong>Advantages of Modified Atmosphere Packaging:</strong><strong></strong></p> <p>MAP is a more versatile process compared to vacuum packaging. While vacuum packaging relies solely on removing air, MAP can be tailored to specific food items, using different gases and ratios of gases in the mixture to provide an extended shelf life while preserving the quality and appearance of the product. </p> <p>For instance, the gas composition involving CO2 and O2 in the modified atmosphere may vary depending on the type of fish being packaged. Oily fish, for example, benefits from a different atmosphere than shrimp. Additionally, the gas mixture used for red meat differs from that used for bread.</p> <p><strong>Carbon Dioxide Sensors in MAP:</strong><strong></strong></p> <p>Carbon dioxide sensors are employed to monitor the changes in carbon dioxide concentration in MAP. One such sensor is the MINIR/ExplorIR-M, a low-power micro-infrared carbon dioxide sensor from GSS, which consumes only 3.5mW of power. It is an ideal choice for battery-powered devices and portable equipment, making it suitable for the gas storage of fruits and vegetables within the MAP system.</p> <p>The SprintIR®-W is another CO2 sensor that offers high-speed measurement capability, taking up to 20 readings per second. This sensor is well-suited for applications requiring rapid individual measurements or where CO2 concentrations change quickly.</p> <p>It features a standard flow-through adapter, allowing high-speed passage of CO2 gas over the optical sensor. Customized adapters can also be used based on specific installation requirements. The SprintIR®-W utilizes patented NDIR solid-state LED optical technology, enabling it to respond to rapidly changing CO2 levels without compromising its performance.</p> <p><strong>Benefits and Specifications of CO2 Sensors:</strong></p> <p>• 20 readings per second</p> <p>• Optional customized flow adaptors</p> <p>• Low power CO₂ sensor</p> <p>• Solid-state LED optical technology</p> <p>• UART data interface</p> <p>• Built-in auto-zero function</p> <p>• Optional diffusion sampling</p> <p><strong>Applications</strong></p> <p>• Healthcare</p> <p>• Food Packaging</p> <p>• Sport Science</p> <p>• CO2 Fire Suppression Deployment</p> <p><strong>CO₂ Sensor Specifications</strong></p> <p>Measurement Ranges 0-5%, 0-20%, 0-60%, 0-100%</p> <p>Accuracy (typ.) 0-60% ±(70ppm, +5% of reading)</p> <p>0-100% ±(300ppm, +5% of reading)</p> <p>Time to 1st Reading <0.5 Seconds</p> <p>Response Time Flow Dependent</p> <p>Readings per Second 20</p> <p>Sample Method Solid-state LED NDIR Diffusion</p> <p>Electrical and Mechanical Specifications</p> <p>Measurement Output UART</p> <p>Supply Voltage 3.25V – 5.5V</p> <p>Power Consumption (typ.) 35mW @3.3V</p> <p>Dimensions and Weight 42.45mm x 25mm x 37mm,7g</p> <p>Operating Conditions</p> <p>Operating Conditions – Temperature 0°C to 50°C</p> <p>Operating Conditions – Humidity 0-95% RH, non-condensing</p> <p>Storage Conditions – Temperature -40°C to +70°C</p> <p>Ambient Operating Pressure 500mbar to 2bar</p> <p>Sensor Lifetime >15 years</p> <p>Environmental Compliance RoHS and REACH</p> <p><strong>Conclusion:</strong><strong></strong></p> <p>Modified Atmosphere Packaging offers a practical alternative to vacuum packaging, providing enhanced product visibility. Vacuum packaging relies on reduced pressure, causing packaging materials to collapse tightly around the product. </p> <p>This can distort the appearance of certain products, such as fresh meat. Vacuum packaging may also cause deformation and compromise critical characteristics for certain products like crumbly cheese. In contrast, MAP offers greater practicality. By utilizing carbon dioxide sensors, the carbon dioxide concentration can be monitored effectively, ensuring optimal gas environments and extending the shelf life of packaged food.</p> <p>MAP technology, combined with accurate CO2 sensing, continues to drive advancements in food preservation, enabling consumers to enjoy fresher and safer food products for longer periods.</p>]]></content:encoded> </item> <item> <title>Proximity Sensors for Mechanical Automation Packaging</title> <link>https://packprintmachine.com/proximity-sensors-for-mechanical-automation-packaging/</link> <dc:creator><![CDATA[Packprint Machine]]></dc:creator> <pubDate>Sun, 16 Jul 2023 10:06:25 +0000</pubDate> <category><![CDATA[Technology]]></category> <category><![CDATA[Business]]></category> <guid isPermaLink="false">https://packprintmachine.com/?p=69</guid> <description><![CDATA[In mechanical manufacturing, the widespread application of automation technology has significantly improved work environments, reduced labor intensity, lowered costs, and increased production efficiency.  As machines consist of various components that need to be assembled in a specific sequence and according to corresponding processes, automated assembly systems have been implemented to replace manual assembly.

It employs a patented method called EDISEN to detect changes in capacitance on the sensing board. </p> <p>The variation in static capacitance, which is inversely related to dynamic capacitance, is automatically compensated using continuous auto-calibration. The sensing board, such as conductive foil, can be connected to IC1 via coaxial cables. These eight input channels operate independently. </p> <p>The sensor matrix arrangement also offers a built-in option to interrupt generation only when two channels are simultaneously activated or to suppress additional outputs when two are already active.</p> <p><strong>Features of Microdul AG’s PCA8885 Proximity Sensor:</strong></p> <ul><li>AEC-Q100 compliant for automotive applications</li> <li>Dynamic touch and proximity sensor with eight sensor channels</li> <li>Support for remote connection and sensor matrix arrangement</li> <li>Adjustable response time</li> <li>Adjustable sensitivity: continuous auto-calibration and digital processing capable of handling up to 6mm acrylic glass</li> <li>Direct and latch switch modes</li> <li>I2C fast mode+(Fm) compatible interface</li> <li>Interrupt output</li> <li>Voltage range (VDD=2.5V-5.5V)</li> <li>Sleep mode (IDD<100n) for low-power battery operation</li> <li>Possible IDD of approximately 10μA</li> <li>Temperature range (-40°C to 85°C)</li></ul> <p><strong>Applications of Microdul AG’s PCA8885 Proximity Sensor:</strong></p> <ul><li>Switches for explosive environments</li> <li>Audio control: on/off, channel, volume</li> <li>Anti-tamper switches</li> <li>Faucet switches</li> <li>Portable communication and entertainment devices</li> <li>White goods control panels</li></ul> <p><strong>Conclusion:</strong></p> <p>Proximity sensors ensure packaging quality and error reduction in mechanical automation packaging technology. </p> <p>Microdul AG’s PCA8885 proximity sensor is an example of advanced technology that offers features such as dynamic touch and proximity sensing, adjustable response time, and compatibility with various applications. </p> <p>By detecting the presence of magnetic or magnetizable substances, these sensors contribute to improved automation, higher efficiency, and enhanced product quality. </p>]]></content:encoded> </item> <item> <title>Photoelectric Sensors for Automated Packaging Technology</title> <link>https://packprintmachine.com/photoelectric-sensors-for-automated-packaging/</link> <dc:creator><![CDATA[Packprint Machine]]></dc:creator> <pubDate>Sun, 16 Jul 2023 09:54:17 +0000</pubDate> <category><![CDATA[Technology]]></category> <category><![CDATA[Business]]></category> <guid isPermaLink="false">https://packprintmachine.com/?p=66</guid> <description><![CDATA[With the advancement of science and technology and the increasing market competition, the requirements for food production companies and automated packaging facilities are increasing.

This scarcity of air deprives microorganisms of their survival conditions, thereby ensuring the freshness, absence of diseases and prevention of spoilage in meat products.</p> <p><strong>Benefits of Vacuum Packaging</strong></p> <p>Processed meats are already sterilized products, and exposure to external oxygen can lead to the proliferation of harmful molds. Vacuum packaging effectively prevents microorganisms in meat products from coming into contact with oxygen and inhibits mold growth.</p> <p>The primary function of vacuum packaging is to remove oxygen, which helps prevent food spoilage. The principle behind it is relatively simple: food spoilage and decay are primarily caused by microbial activity, and most microorganisms, such as molds and yeast, require oxygen to survive. Vacuum packaging exploits this principle by extracting oxygen from the packaging bag and the food cells, depriving the microorganisms of their living environment.</p> <p>To achieve the desired anti-mold and anti-bag inflation effects, controlling the residual oxygen level inside the packaging as low as possible is crucial, which means achieving a high level of vacuum. Therefore, controlling the vacuum level in vacuum packaging is of utmost importance. For vacuum level detection, the MTCS2300 thermal conductivity gas sensor is recommended.
