What are the three layers of aluminum plastic film?

The aluminum plastic film must be constructed of three layers of materials held together with adhesives in order for it to have the aforementioned properties. The structure is the outer resistance layer, the barrier layer, and the heat sealing layer from the outside to the inside.

What is aluminum plastic film & why is it important?

The aluminum plastic film is a crucial material in the lithium battery industry chain’s upstream packaging, representing 10-20% of total material cost for pouch batteries.

What is aluminum plastic film?

The aluminum plastic composite film, referred to as aluminum plastic film, is a composite flexible packaging shell material used to package lithium-ion batteries and is often used in soft pack batteries and blade batteries.

What is a dry-processed aluminum plastic film?

The dry process is to directly bond aluminum foil and CPP through an adhesive and then press them together. Since the CPP does not need secondary crystallization after the high temperature in this process, the dry-processed aluminum plastic film has good drawing performance and good appearance.

Why do we seal monolithic cells with aluminum plastic film?

Sealing the assembled monolithic cells with aluminum plastic film can play an important role in protecting the internal electrodes and isolating the external environment.

What is the manufacturing process of aluminum plastic film?

The mainstream manufacturing process of aluminum plastic film can be divided into the dry method and the thermal method. The dry process is to directly bond aluminum foil and CPP through an adhesive and then press them together.
