Multi-layer Co-extruded Sheets from China Factory – Top Suppliers for Packaging Solutions
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.
Composed of hard sheet film and co-extruded film, they are characterized by favorable hardness and forming properties, extremely high optical properties, extremely high plastic protection, high resistance to oxygen and moisture, extremely high heat sealing performance, low cost, and prolonged service life of products.
Multi-layer co-extruded sheets from Hysum are a versatile and reliable packaging material for pharmaceutical products, offering excellent barrier properties, strength, and customization options. As a custom pharma packaging supplier, utilizing multi-layer co-extruded sheets can help ensure the safe and effective delivery of medications and medical products to patients.

What are high-barrier co-extruded sheets?
High-barrier co-extruded sheets are multi-layer packaging materials that combine different polymers (such as PE, EVOH, and nylon) into a single sheet. Each layer provides specific performance benefits like gas resistance, sealability, and physical strength.
What are the main characteristics of co-extruded multilayer films?
They feature favorable hardness, excellent forming properties, high optical clarity, reliable plastic protection, high resistance to oxygen and moisture, excellent heat sealing performance, and cost-efficiency while extending product shelf life.
Which industries commonly use these high-barrier sheets?
These multi-layer sheets are widely applicable across the cosmetics, food, and medical/pharmaceutical industries due to their versatile protection properties and customizability.
How does EVOH contribute to pharmaceutical packaging?
EVOH (ethylene vinyl alcohol) provides excellent gas barrier properties, protecting sensitive pharmaceutical products from oxygen and other environmental factors that could degrade the medicine.
Can these multi-layer sheets be customized?
Yes. Co-extruded multilayer films and sheets are highly customizable and can be tailored to specific requirements, including thickness variations, custom colors, and unique surface finishes.
