High-Barrier Multi-Layer Films from China Suppliers - Co-Extruded PA and PE for Industrial & 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 |
Asymmetric co-extruded films and bags
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.
Symmetrical nylon co-extruded films and bags
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.
Symmetrical EVOH co-extruded film
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...
Asymmetrical high-barrier bags
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.
Vacuum surlyn films
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...
Sealing strip for aseptic packaging
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.
Frequently Asked Questions
What are the differences between General, High-temperature, and Enhanced air cushion packaging?
General type uses PE/PA/PE structure for ordinary air cushion packaging up to 60°C. High-temperature type (PE/PA/PE) withstands up to 75°C for 24 hours under high humidity, ideal for packaging high-end electronics. Enhanced type (PE/PA/PA/PE) offers superior physical properties and puncture resistance.
What are the primary applications of asymmetric co-extruded films and bags?
They are principally used for embossed rolls, embossed bags, vacuum bags, industrial packaging, frozen food packaging, and applications requiring stretch-formed packaging.
What makes symmetrical EVOH co-extruded film suitable for food packaging?
Symmetrical EVOH co-extruded film provides a high barrier to oxygen, carbon dioxide, and other gases. It features low-temperature heat sealing for efficiency, easy-peel design, and can be laminated with various materials to replace composite materials in applications like toothpaste and jelly cover films.
How do vacuum surlyn films extend the shelf life of preserved foods?
They regulate the air composition to reduce oxygen levels, suppressing food spoilage and microbial growth. They adhere tightly to the food, reducing physical damage and preserving flavor and quality.
Where are sealing strips for aseptic packaging typically used?
They are used with milk packaging, Tetra Pak packaging, and beverage packaging, offering low-temperature heat sealing and barrier protection against water vapor and oxygen.
What are the advantages of symmetrical nylon co-extruded films?
They feature heat-sealing properties on both sides and are widely used in electronics, air column bags, drinking water, load-bearing packages, and hot foils.
