High-Barrier Co-Extruded Multi-Layer Films for Industrial & Frozen Foods – China Suppliers & 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 different types of air cushion packaging structures?
The packaging structures include General type (PE/PA/PE) for ordinary air cushion packaging, High-temperature type (PE/PA/PE) designed for high temperature and high humidity testing, and Enhanced type (PE/PA/PA/PE) for improved physical properties and puncture resistance.
What are the main applications of asymmetric co-extruded films and bags?
Asymmetric co-extruded films and bags are primarily used for embossed rolls, embossed bags, vacuum bags, industrial packaging, frozen food packaging, and applications requiring stretch formed packages.
How do symmetrical nylon co-extruded films benefit packaging processes?
Symmetrical nylon co-extruded films feature heat sealing properties on both sides of the film. They are co-extruded from PA and PE resins and are mainly used for electronics, air column bags, drinking water, load-bearing packages, and hot foils.
What material composition is used for symmetrical EVOH co-extruded films?
Symmetrical EVOH co-extruded films are principally co-extruded from MPE, LLDPE, LDPE, TIE, and EVOH. They provide a high barrier to oxygen, carbon dioxide, and other gases, and offer low-temperature heat sealing behavior to improve operational efficiency.
How do vacuum surlyn films extend the shelf life of food?
Vacuum surlyn films reduce oxygen content by regulating the air composition, which suppresses food spoilage and microbial growth. They enable protective trays and surlyn films to adhere tightly to the food, preserving its flavor and quality while reducing physical damage.
What are the key characteristics of sealing strips for aseptic packaging?
Co-extruded from PE and other materials, these sealing strips offer excellent low-temperature heat sealing, a reliable barrier against water vapor and oxygen, low elongation at break for easy cutting, and a matte finish. They are commonly used with milk, Tetra Pak, and beverage packaging.
