OPA/AL/PVC Laminated Foil Film

OPA/AL/PVC laminated foil is a multilayer composite material widely used for packaging in the food, pharmaceutical, and cosmetic industries. This composite material combines the advantages of each layer to provide excellent barrier properties, mechanical strength and processability.

OPA/AL/PVC laminated foil

Component Materials of OPA/AL/PVClaminated foil:

1. OPA (Oriented Polyamide, Polyamide, Nylon) layer:

– CHARACTERISTICS: The OPA layer provides good mechanical strength and puncture resistance, as well as excellent gas and water vapor barrier properties.

– Application: This material is usually used for packaging that requires high strength and durability, and can effectively protect the food inside from the external environment.

2. AL (Aluminum Foil) layer:

– Characteristics: Aluminum foil layer has excellent barrier properties, which can effectively isolate light, oxygen and moisture, preventing oxidation and spoilage of food. As an intermediate layer, it provides excellent barrier performance to ensure the freshness and safety of the contents.

– Application: Aluminum foil layer is commonly used to package food products that are susceptible to oxidation, such as dried fruits, coffee, spices, etc.

3. PVC (Polyvinyl Chloride) layer:

– Characteristics: PVC layer provides good sealing, molding, heat sealing performance, softness, high transparency, and is usually used in the outer layer of packaging to increase the stability of the structure.

– APPLICATIONS: PVC layers are commonly used in bags, blister packs, etc. to provide additional protection and aesthetics.

Production process of OPA/AL/PVC laminated foil:

– Co-extrusion: Different materials are extruded simultaneously through a multi-layer co-extruder to form a multi-layer structure.

– Laminating: Different materials are laminated together by adhesives or other methods to form composite materials.

– Printing and Coating: Printing and coating as needed to increase the aesthetics and functionality of the package.

Advantages of OPA/AL/PVC laminated foils:

– Excellent barrier properties: this composite material effectively blocks moisture, oxygen and light, extending the shelf life of food products.

– Good mechanical properties: combining the advantages of the different materials, it has a high resistance to tearing and puncture, making it suitable for a wide range of packaging formats.

– Good heat sealing properties: ensures that the package is hermetically sealed and prevents leakage.

– Suitable for a wide range of packaging needs, from simple bagging to complex multi-layer packaging

– Versatility: suitable for a wide range of food packaging, but also can be used in other areas such as pharmaceuticals and cosmetics.

– Customizability: Different combinations of thickness and structure are possible according to customers’ needs.

Application areas of OPA/AL/PVC laminated foil:

– Food Packaging: Used for packaging cookies, candies, nuts, coffee and other foods to maintain the freshness and taste of the food.

– Pharmaceutical packaging: used for packaging tablets, capsules, liquid drugs, etc., to ensure the stability and effectiveness of drugs.

– Cosmetic Packaging: Used for packaging skin care products, perfume, etc. to prevent product deterioration and pollution.

– Others: also used for packaging of medical supplies, electronic components and other fields.

When using OPA/AL/PVC laminated foil, you need to make sure that the material complies with food safety standards, especially in applications that come into direct contact with food, to ensure that no harmful substances are released.
