The vacuum degree is a crucial parameter in the performance of a thick film thermoforming vacuum packaging machine. As a leading supplier of Thick Film Thermoforming Vacuum Packaging Machines, I'm often asked about the vacuum degree these machines can achieve. In this blog, I'll delve into the details of the vacuum degree of thick film thermoforming vacuum packaging machines, exploring its significance, influencing factors, and the typical vacuum degrees our machines can reach.
Significance of Vacuum Degree in Thick Film Thermoforming Vacuum Packaging
Vacuum packaging is a widely used method in various industries, including food, electronics, and pharmaceuticals. The main purpose of vacuum packaging is to remove air from the packaging cavity, creating a low - pressure environment. This process has several important benefits:
- Preservation: By removing oxygen from the package, the growth of aerobic bacteria, mold, and other microorganisms is inhibited. This significantly extends the shelf - life of perishable products such as food. For example, in the food industry, vacuum - packed meats can last much longer compared to those stored in normal air conditions.
- Protection: Vacuum packaging protects products from oxidation, which can cause discoloration, loss of flavor, and deterioration of quality. It also prevents the entry of dust, moisture, and other contaminants, ensuring the integrity of the product during storage and transportation.
- Space - Saving: Vacuum - packed products take up less space as the air is removed from the package. This is particularly beneficial for products with irregular shapes or those that need to be stored in large quantities.
Factors Influencing the Vacuum Degree of Thick Film Thermoforming Vacuum Packaging Machines
The vacuum degree that a thick film thermoforming vacuum packaging machine can reach is affected by several factors:
- Pump Performance: The vacuum pump is the heart of the vacuum system in the packaging machine. Different types of vacuum pumps have different pumping speeds and ultimate vacuum levels. For example, rotary vane pumps are commonly used in many packaging machines. They can achieve relatively high vacuum degrees, but their performance may be affected by factors such as oil quality and pump wear. The higher the pumping speed and the lower the ultimate vacuum level of the pump, the better the vacuum performance of the machine.
- Sealing Performance: A good sealing system is essential for maintaining the vacuum degree. Any leakage in the packaging cavity will cause the vacuum degree to drop. The quality of the sealing materials, the design of the sealing structure, and the accuracy of the sealing process all affect the sealing performance. For instance, if the sealing gasket is damaged or not properly installed, air will leak into the package, reducing the vacuum degree.
- Packaging Material: The permeability of the packaging material to air also plays a role in the vacuum degree. Some materials, such as certain types of plastics, have lower air permeability than others. Using high - barrier packaging materials can help maintain a higher vacuum degree inside the package for a longer time.
- Product Characteristics: The nature of the product being packaged can impact the vacuum degree. Products that release gas, such as some fresh foods, may make it difficult to achieve and maintain a high vacuum degree. Additionally, products with large surface areas or porous structures may trap air, which can be challenging to remove completely during the vacuuming process.
Typical Vacuum Degrees of Our Thick Film Thermoforming Vacuum Packaging Machines
Our company offers a range of thick film thermoforming vacuum packaging machines, each designed to meet different customer needs. The vacuum degrees our machines can reach typically fall within a certain range.
- General - Purpose Machines: For our standard Thick Film Thermoforming Machine, which are suitable for a wide variety of products, we can usually achieve a vacuum degree of around 10 - 100 Pa. This level of vacuum is sufficient for most common packaging applications, such as packaging dry foods, small consumer goods, and some light - duty industrial products.
- High - Performance Machines: Our Large Thick Film Thermoforming Packaging Machine and Multifunction Thick Film Thermoforming Machine are equipped with more advanced vacuum systems and sealing technologies. These machines can reach a vacuum degree of up to 1 - 10 Pa. This high - level vacuum is ideal for products that require strict protection, such as high - end food products, precision electronics, and sensitive pharmaceutical items.
Measuring and Controlling the Vacuum Degree
To ensure the accuracy and consistency of the vacuum degree, our machines are equipped with advanced vacuum measurement and control systems.
- Vacuum Sensors: We use high - precision vacuum sensors to measure the vacuum degree inside the packaging cavity in real - time. These sensors can provide accurate data, allowing the machine to adjust the vacuuming process accordingly.
- Control Systems: Our machines are integrated with intelligent control systems that can automatically adjust the operation of the vacuum pump based on the measured vacuum degree. If the vacuum degree is lower than the set value, the pump will continue to operate until the desired vacuum level is reached. This ensures that each package is vacuum - packed with the same high - quality standard.
Conclusion
The vacuum degree is a vital factor in the performance of thick film thermoforming vacuum packaging machines. Our company, as a professional supplier, is committed to providing machines with excellent vacuum performance. Whether you need a general - purpose machine for common packaging applications or a high - performance machine for demanding products, we have the right solution for you.
