Process flow comparison：

Disadvantages of adding smootheners：
1, high temperature storage and high temperature transportation of aluminum-plastic film will cause the precipitation of slippery agent, affecting the molding performance;

2. Compared with the aluminum-plastic film without adding the smoothing agent, the aluminum-plastic film with the addition of the smoothing agent has a short storage time and poor timeliness.

Advantages of not adding a smoothing agent:
Our company's aluminum-plastic film process and technology, no longer need to apply smoothing agent, and can maintain low friction coefficient, improve the production efficiency of customers And pass rate, longer storage cycle.

● The use of aluminum plastic film

Aluminum-plastic film is used in the outer packaging material of soft-pack lithium batteries

● Characteristics of aluminum-plastic film

- The role of aluminum-plastic film is to protect the safety of the battery cell and has extremely high quality requirements, including:

- High barrier property, 10000 times higher than ordinary aluminum-plastic film barrier；

- Good cold stamping formability, convenient for different shapes of lithium battery production molding；

- High puncture resistance, prevent battery leakage,   short-circuit ；

- Electrolyte resistance, the inner material does not react with the electrolyte, to ensure the safety of the battery ；

- High temperature resistance and insulation
