High-Barrier Multi-Layer Co-Extruded Films from China Suppliers - PA & PE for Industrial and Frozen Food Packaging Factory
| Product name | Product structure | Application Characteristics |
|---|---|---|
| General type | PE/PA/PE | Ordinary air cushion packaging products that can withstand constant humidity at constant temperature (60°C) |
| High-temperature type | PE/PA/PE | Suitable for high temperature and high humidity (at high temperature) tests; stay below 75 degrees for 24 hours; tested materials can be used to package high-end electronic components |
| Enhanced type | PE/PA/PA/PE | Better physical properties and puncture resistance |
Embossed rolls, embossed bags, and vacuum bags
Co-extruded from PA and PE resins; used to make ordinary packaging bags directly by virtue of the temperature resistance difference between PA and PE resins; principally applicable to industrial packaging and frozen food packaging, as well as some applications requiring stretch formed package.
PA resin is essentially a polar material, and its product can be printed and laminated directly; when compound-designed, it can be extensively used for cover film, sealing film, etc.
Buffer package, degradable air column bags, film bladders for water bags, lining bags for bulk bags, and colorprinted composite cover films and bags
Co-extruded from PA and PE resins; with heat sealing properties on both sides of the film, the symmetrical nylon is principally used for electronics, air column bags, drinking water, load-bearing package, hot foils, etc.
Toothpaste films, jelly cover films, packaging of ice cream, etc.
Principally co-extruded from MPE, LLDPE, LDPE, TIE, EVOH and other materials; high barrier to oxygen, carbon dioxide and other gases; certain low-temperature heat sealing behavior helps improve customers' operational efficiency; designed for easy peel; symmetrical EVOH films can be laminated with a variety of materials; different plastics are combined into thin films at one time to replace composite materials, having been...
Packaging of foods with a longer shelf life
Co-extruded from EVOH, PA, and PE resins, featuring strong barrier; also useful as printed composite substrate for forming dies.
Various preserved foods
The air composition in the box is regulated by special equipment to reduce the oxygen content, thereby effectively suppressing food spoilage and microbial growth; it can significantly reduce or even avoid food exposure to the air and enables protective trays and surlyn films to adhere tightly to food, thereby reducing physical damage and extend the shelf life of product; this goes far towards preserving the flavor and quality of meat, giving end...
Used with milk packaging, Tetra Pak packaging, beverage packaging
Co-extruded from PE and other materials; excellent low temperature heat sealing performance, and a certain barrier effect on water vapor and oxygen; easy to cut off, exhibiting low elongation at break; matte effect.
Q: What is the main difference between General, High-temperature, and Enhanced type air cushion packaging?
The General type is designed for ordinary air cushion packaging under constant temperature (60°C). The High-temperature type can withstand high temperature and high humidity tests (staying below 75°C for 24 hours), making it suitable for high-end electronic components. The Enhanced type features a 4-layer structure (PE/PA/PA/PE) for superior physical properties and puncture resistance.
Q: What are the primary applications of asymmetric co-extruded films and bags?
Asymmetric co-extruded films and bags are mainly used for embossed rolls, embossed bags, and vacuum bags. They are widely applicable to industrial packaging, frozen food packaging, and applications requiring stretch-formed packaging.
Q: How does EVOH co-extruded film achieve its high barrier properties?
Symmetrical EVOH co-extruded film is co-extruded from multiple materials including MPE, LLDPE, LDPE, TIE, and EVOH. This unique combination provides an exceptional barrier to oxygen, carbon dioxide, and other gases, making it ideal for packaging items like toothpaste, jelly, and ice cream.
Q: What are the benefits of using vacuum surlyn films for preserved foods?
Vacuum surlyn films regulate the air composition inside the package to reduce oxygen content, which suppresses food spoilage and microbial growth. They adhere tightly to the food, reducing physical damage and extending shelf life while preserving flavor and quality.
Q: What applications are suitable for sealing strips in aseptic packaging?
Sealing strips are designed for milk packaging, Tetra Pak packaging, and beverage packaging. They offer excellent low-temperature heat sealing performance and act as a reliable barrier against water vapor and oxygen.
