Top-blown multi-layer co-extruded high-barrier films

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.

Asymmetric co-extruded films and bags

Application: Embossed rolls, embossed bags, and vacuum bags

Product characteristics:

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.

Asymmetric co-extruded films and bags

Symmetrical nylon co-extruded films and bags

Application: Buffer package, degradable air column bags, film bladders for water bags, lining bags for bulk bags, and colorprinted composite cover films and bags

Product characteristics:

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 nylon co-extruded films and bags

Symmetrical EVOH co-extruded film

Application: Toothpaste films, jelly cover films, packaging of ice cream, etc.

Product characteristics:

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 extensively used for vacuum food packaging bags, medical, agricultural and industrial packaging, etc.

Symmetrical EVOH co-extruded film

Asymmetrical high-barrier bags

Application: Packaging of foods with a longer shelf life

Product characteristics:

Co-extruded from EVOH, PA, and PE resins, featuring strong barrier; also useful as printed composite substrate for forming dies.

Asymmetrical high-barrier bags

Vacuum surlyn films

Application: Various preserved foods

Product characteristics:

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 users a great cooking experience, and helping reduce food waste.

Vacuum surlyn films

Sealing strip for aseptic packaging

Application: Used with milk packaging, Tetra Pak packaging, beverage packaging

Product characteristics:

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.
