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 packaging (PE/PA/PE) handles standard constant temperature and humidity (60°C). High-temperature type (PE/PA/PE) stays stable below 75°C for 24 hours under high humidity, making it suitable for 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?
Asymmetric co-extruded films and bags are mainly used for embossed rolls, embossed bags, vacuum bags, industrial packaging, frozen food packaging, and stretch-formed packaging applications.
Why are symmetrical nylon co-extruded films used for air column bags and electronics?
Symmetrical nylon co-extruded films are co-extruded from PA and PE resins, which provides reliable heat sealing properties on both sides of the film. This makes them ideal for buffer packages, degradable air column bags, and load-bearing packages.
How does symmetrical EVOH co-extruded film improve packaging efficiency?
Symmetrical EVOH film features low-temperature heat sealing behavior to improve operational efficiency. It provides a high barrier to oxygen and carbon dioxide, is designed for an easy peel, and can replace traditional composite materials by combining different plastics at one time.
How do vacuum surlyn films extend the shelf life of preserved foods?
Vacuum surlyn films reduce oxygen exposure by allowing the film to adhere tightly to the food. This regulates air composition, suppresses microbial growth, minimizes physical damage, and preserves the food's flavor and quality.
What are the key characteristics of sealing strips for aseptic packaging?
These sealing strips are co-extruded from PE and other materials, offering excellent low-temperature heat sealing, a barrier effect against water vapor and oxygen, low elongation at break for easy cutting, and a matte finish.
