Application fields of EVOH plastic sheets
In the food packaging industry, three-layer EVOH plastic sheets offer high barrier properties that effectively extend the shelf life of food. They prevent the penetration of oxygen and moisture, thereby preserving the freshness and flavor of the food.
In the pharmaceutical industry, three-layer EVOH plastic sheets protect medications from external environmental factors, ensuring the stability and efficacy of the drugs.
The cosmetics industry demands high standards for packaging materials, and three-layer EVOH plastic sheets provide excellent protection, maintaining the stability of cosmetic products.
What are EVOH Three-Layer Co-Extruded Plastic Sheets?
EVOH three-layer co-extruded plastic sheets are composite plastic sheets produced using co-extrusion technology, where EVOH is used as one of the key layers to provide exceptional barrier properties. The three-layer co-extrusion technology allows for the simultaneous extrusion of EVOH with other plastic materials to create a composite sheet with different performance layers. Typically, this three-layer structure includes:
- Outer Layer: Usually made of durable plastic materials such as polyethylene or polypropylene, providing mechanical strength and durability.
- Middle Layer (EVOH Layer): Primarily responsible for blocking oxygen, moisture, and other gases, ensuring the safety and freshness of the inner product.
- Inner Layer: In contact with the product, typically made from plastic materials compatible with the product.
Applications of Three-Layer EVOH Plastic Sheets
1、Food Packaging In the food packaging industry, the high barrier properties of three-layer EVOH plastic sheets effectively extend the shelf life of food. They prevent the penetration of oxygen and moisture, thereby preserving the freshness and flavor of the food. Major applications include:
Composite Food Bags: Used for packaging dried fruits, snacks, cooked foods, etc.
Food Trays and Packaging Films: Maintain the quality and nutrition of food.
2、Pharmaceutical Packaging In the pharmaceutical industry, three-layer EVOH plastic sheets protect medications from external environmental factors, ensuring their stability and efficacy. Common applications include:
Blister Packs: Protect tablets and capsules from oxygen and moisture.
Pharmaceutical Bags and Containers: Ensure the safety of medications during transport and storage.
3、Cosmetic Packaging The cosmetics industry requires high standards for packaging materials, and three-layer EVOH plastic sheets provide excellent protection to maintain the stability of cosmetic products. Major applications include:
Cosmetic Tubes and Bottle Liners: Prevent product exposure to air, extending product lifespan.
Cosmetic Packaging Bags: Protect products from light and oxygen to maintain quality.
