Five-layer co-extruded high barrier film: the preferred material for the packaging industry

The high barrier property of the five-layer co-extruded high barrier film is one of its most notable features. Through precise co-extrusion technology, resin materials with excellent barrier properties such as nylon (PA) and ethylene-vinyl alcohol copolymer (EVOH) are used as barrier layers to effectively prevent the penetration of gases such as oxygen and water vapor. This feature makes the five-layer co-extruded high barrier film widely used in the food, medicine and other industries. In food packaging, it can prevent food from oxidation and deterioration, and maintain the freshness and taste of food; in pharmaceutical packaging, it can ensure the sterility and stability of drugs and ensure the safety of patients' medication. In addition, the five-layer co-extruded high barrier film can also effectively block the exposure to harmful rays such as ultraviolet rays, protect the products in the package from the effects of light aging, and further extend the shelf life of the products.
In addition to high barrier properties, the five-layer co-extruded high barrier film also has high strength and excellent physical properties. Through the compounding of multiple layers of materials, the film has high tensile strength and wear resistance, and can withstand greater external forces and pressures. This feature makes the five-layer co-extruded high barrier film not easy to break during the packaging process, and can protect the product from damage by the external environment. At the same time, its good flexibility and plasticity also make the film easy to process into packaging containers of various shapes and sizes to meet the packaging needs of different products.
Easy processing is another major advantage of the five-layer co-extruded high barrier film. During the production process, the film can be processed through a variety of processes such as heat sealing, printing, and cutting to form a variety of exquisite packaging products. This feature not only improves production efficiency, but also reduces production costs, making the five-layer co-extruded high barrier film more competitive in the market.
The five-layer co-extruded high barrier film also has good environmental performance. With the increasing global environmental awareness, more and more consumers have begun to pay attention to the sustainability and recyclability of packaging. As an environmentally friendly packaging material, the five-layer co-extruded high barrier film is usually degradable or easy to recycle. This not only helps to reduce environmental pollution, but also conforms to the concept of sustainable development.
