Functional characteristics of mesh vacuum bags

Mesh vacuum bag is a type of vacuum packaging bag with a special pattern, with one side having a distinct mesh pattern and the other side being a smooth flat surface. This design not only makes the bag more distinctive in appearance, but also enhances its practicality. The mesh vacuum bag is made of high-quality materials and has good sealing performance. It can effectively isolate air, moisture, and bacteria, thereby extending the shelf life of food.
Mesh vacuum bag is a high-quality composite film packaging bag with multiple functional characteristics. The following is a detailed summary of its functional characteristics:
1、 High barrier properties
Material structure: The mesh vacuum bag adopts special materials and processes, such as seven layer co extrusion film technology, in which PA (polyamide) or EVOH (ethylene vinyl alcohol copolymer) is used as a barrier layer, which can effectively prevent the penetration of substances such as oxygen, water vapor, and oil.
Maintaining Quality: This high barrier performance helps to maintain the original quality of the product, which is particularly important for products such as food and medicine that are prone to moisture and oxidation.
2、 Good mechanical performance
Tensile strength: Mesh vacuum bags have excellent tensile strength, tear strength, and impact strength, and can withstand various external impacts during transportation and storage, protecting products from damage.
Flexibility: At the same time, its good flexibility is also easy to process and use. It can be used with various sealing machines without selecting machines, suitable for various scenarios such as homes, restaurants, snack catering, takeout, small manufacturers, etc.
3、 High transparency
Product Display: Although one side of the mesh vacuum bag is embossed with patterns, the other side is usually smooth and transparent, which can clearly display the contents of the product and improve its beauty and attractiveness.
Enhance trust: This transparency not only facilitates consumers to view product status, but also enhances the trust of packaging.
4、 Flat pattern design
Uniform force distribution: The flat pattern design of the mesh vacuum bag enables the packaging bag to form a uniform pressure distribution during vacuum pumping, ensuring that food is evenly stressed inside the packaging bag and avoiding damage during transportation or storage.
No dead corners mode: The design of microchannels makes vacuum extraction more convenient, maintaining the freshness and shelf life of food.
5、 Moisture proof and oxidation resistant
Moisture resistance: The mesh vacuum bag material has a dense structure and excellent moisture resistance, which can effectively prevent the product from getting damp and deteriorating.
Anti oxidation performance: The special material structure can effectively prevent oxygen from entering the bag and prevent product oxidation and deterioration.
6、 High security
Glue free composite: The seven layer co extrusion material design avoids problems such as glue overflow and contamination that may occur in traditional composite processes, ensuring the stability and safety of packaging bags at high temperatures.
No printing ink pollution: Mesh vacuum bags do not require printing, have no ink pollution, and have high safety.
7、 Extend shelf life
Vacuum packaging technology: Through vacuum packaging technology, mesh vacuum bags can remove oxygen and moisture from the packaging, inhibit the growth and reproduction of microorganisms, and extend the shelf life of products.
In summary, mesh vacuum bags have various functional characteristics such as high barrier properties, good mechanical properties, high transparency, flat pattern design, moisture and oxidation resistance, high safety, and extended shelf life. These characteristics make mesh vacuum bags have broad application prospects in packaging fields such as food, medicine, precision instruments, and hardware machinery.
