7 Layers Low temperature PA PE Co-extruded Film Manufacturers

Does the design of the 7-layer structure of the 7-layer low-temperature PA PE co-extruded film take into account specific performance requirements, such as barrier properties, strength, weather resistance, etc.?

Technical considerations for the design of the 7-layer structure
Barrier properties are a key performance indicator of packaging materials, which are directly related to the shelf life and safety of the packaging contents (such as food, medicine, chemicals, etc.). In the design of Changxi Packaging's 7-layer co-extruded film, special attention is paid to the configuration of the barrier layer. Usually, the PA layer is used as the main barrier layer due to its excellent gas barrier properties (such as oxygen and carbon dioxide). By precisely controlling the thickness and molecular structure of the PA layer and adding specific modifiers, the company can customize the film's barrier efficiency for specific gases, effectively extend the shelf life of the product, and prevent oxidation deterioration or flavor loss. The PE layer provides good water vapor barrier properties, further enhancing the all-round protection of the packaging.
Strength is the ability of packaging materials to resist external damage during transportation, storage and use. Changxi Packaging's 7-layer structure design cleverly combines the high-strength PA layer with the PE layer with excellent toughness to form a "rigid and flexible" composite structure. The PA layer not only has excellent tensile strength and tear strength, but also maintains good toughness under low temperature conditions, avoiding material embrittlement caused by temperature changes. The PE layer, with its good flexibility and impact resistance, enhances the overall durability of the low temperature PA PE film, ensuring that the packaging remains intact in a complex and changeable logistics environment.
Weather resistance refers to the ability of a material to maintain stable performance under the influence of natural environmental factors (such as light, temperature, humidity, rain, microorganisms, etc.). Weather resistance is particularly important for packaging that needs to be stored outdoors for a long time or experiences extreme climatic conditions. Changxi Packaging's 7-layer co-extruded film effectively improves the film's resistance to light aging, heat aging and hydrolysis by adding specific additives such as anti-ultraviolet absorbers, antioxidants and light stabilizers. In addition, by optimizing the bonding technology between the layers, it is ensured that the layers of the PA PE co-extruded film will not be delaminated in extreme environments, maintaining the integrity of the structure and the stability of the function.
