Multi-layer co-extruded sheets are a type of packaging material that is made up of several layers of different materials that are extruded simultaneously to create a single sheet. These co extruded multilayer films are commonly used in the pharmaceutical, cosmetics and food industry for packaging products. Composed of hard sheet film and co-extruded film, they are characterized by favorable hardness and forming properties, extremely high optical properties.
Applicable for various stretch packages
The multi-layer structure of the co extrusion film allows for a combination of different materials to be used in a single sheet, each layer providing specific properties such as barrier properties, strength, and flexibility. For example, a typical co-extruded sheet used in pharmaceutical packaging may consist of a layer of polyethylene (PE) for its sealability, a layer of ethylene vinyl alcohol (EVOH) for its excellent gas barrier properties, and a layer of nylon for its strength and durability.
Multi-layer co-extruded sheets offer several advantages for pharmaceutical packaging. They provide superior barrier properties against moisture, oxygen, and other environmental factors that can affect the shelf life of drugs. Multilayer film packaging is also resistant to punctures and tears, ensuring the integrity of the product inside. Additionally, co extruded multilayer film and sheets are highly customizable and can be tailored to specific requirements, such as thickness, color, and surface finish.
