cosmetics Aluminum foil seal liner(such as aluminum foil sealing gaskets, paper plastic composite gaskets, etc.) play a role in sealing, preventing leakage, blocking pollution, and extending shelf life in packaging. If used improperly, it may lead to leakage, contamination, or product deterioration. 

When choosing a cosmetics Aluminum foil seal liner, the following three points should be noted:

1. Material matching

Aluminum foil gasket: suitable for lotion, essence and other liquid products, with good oxygen resistance and moisture resistance.

Paper plastic composite gasket: suitable for powder or solid cosmetics, with lower cost but slightly weaker sealing performance.

Easy to tear film gasket: used for high-end skincare products to enhance user experience.

2. Size adaptation

The diameter of the gasket should be slightly larger than the bottle mouth to ensure complete coverage of the sealing surface.

Being too small can lead to poor sealing, while being too large may affect the sealing effect of the sealing machine.

3. Type of heat sealing adhesive

Select the matching hot melt adhesive based on the material of the bottle mouth (PP, PE, PET, glass, etc.) to ensure a firm bond.
