Aluminum foil sealing film is a widely used sealing material in packaging industries such as food, medicine, cosmetics, etc. It is usually composed of a composite of aluminum foil layer, heat sealing layer, and printing layer.

It has excellent barrier properties, which can effectively prevent oxygen, moisture, and light from entering the container, thereby extending the shelf life of the product. 

Problem 1: Poor sealing and leakage

Possible reasons: insufficient temperature/pressure, bottle mouth contamination, inconsistent sealing film size

Solution: Adjust the sealing parameters, clean the bottle mouth, and replace the appropriate sealing film

Problem 2: The sealing film is difficult to tear off

Possible reasons: high heat sealing temperature, thick adhesive layer

Solution: Reduce temperature, choose easy to tear sealing film

Question 3: Oxidation and yellowing of aluminum foil

Possible reasons: Storage environment is humid or hot

Solution: Improve storage conditions and use moisture-proof packaging

Question 4: Wrinkle of sealing film after sealing

Possible reasons: uneven pressure, failure to level the sealing film

Solution: Adjust the sealing machine pressure to ensure that the gasket is flat and fits snugly
