Composite foil

 

Composite foil is a kind of foil made of two or more materials laminated together, combining the advantages of different materials to enhance its barrier properties, strength and functional properties. It is widely used in food packaging, pharmaceutical packaging, architectural decoration, thermal insulation and waterproof materials.

 

1. Characteristics of composite foil

1. High barrier property: composite foil can effectively block moisture, oxygen, light, etc., and extend the shelf life of packaging.

2. Excellent mechanical strength: composite materials combine the characteristics of metal and polymer materials to improve tear resistance and wear resistance.

3. Excellent protective performance: can be used for lithium battery safety protection, effectively inhibit the generation of lithium dendrites, and reduce the risk of internal short circuit of the battery.

4. Multifunctional application: with heat insulation, waterproof, anti-corrosion and other characteristics, suitable for the construction industry and special industrial needs.

2. Specifications

Composite foil can be customized according to different application requirements, and its common alloy materials include:

- 1100 aluminum alloy: with excellent corrosion resistance and processing performance.

 

3. Processing technology

The production of composite foil involves multiple processes to ensure its structural stability and functionality:

1. Adhesive coating: Uniformly apply specific adhesives on the surface of different materials.

2. Pressing and heating: Through high temperature and high pressure, each layer of material is firmly combined to form a composite structure with high strength and stability.

 

4. Application fields
