China Multi-layer Co-extruded Sheets Supplier - High-Quality Packaging Solutions from Our Factory
High-barrier sheets
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.

Frequently Asked Questions
What are multi-layer co-extruded sheets?
Multi-layer co-extruded sheets are advanced packaging materials that combine different polymer layers (such as PE, EVOH, and nylon) into a single sheet during extrusion. This structure integrates the unique properties of each material, such as sealability, strength, and high gas barriers.
Why is EVOH used in co-extruded films?
EVOH (ethylene vinyl alcohol) is incorporated into co-extruded films primarily for its exceptional gas barrier properties. It effectively blocks oxygen and moisture, protecting sensitive products like pharmaceuticals and food from degradation.
What are the main applications of high-barrier sheets?
High-barrier sheets are widely used across various industries requiring protective stretch packaging, including the cosmetics industry, food industry, and medical/pharmaceutical industries.
What advantages do these sheets offer for pharmaceutical packaging?
They provide superior barrier protection against environmental factors, high resistance to punctures and tears, excellent heat sealing performance, and are highly customizable in terms of thickness, color, and finish to prolong drug shelf life.
Can Hysum customize co-extruded sheets for specific packaging needs?
Yes, as a custom pharma packaging supplier, Hysum offers highly customizable multi-layer co-extruded sheets tailored to specific requirements, including thickness, color, surface finish, and barrier levels.
