The three-side sealing aluminum foil bag is one of our traditional products, which is manufactured by full-automatic mechanization, safe and clean as well as its stable quality, high producing efficiency and excellent tightness.

Aluminum foil composite film is a construction of 3 to 4 piles laminated together using adhesives or extruding coating. Typical structure is shown below:

Layer-1: An out layer of polyethylene, which gives material mechanical strength at a wide range of temperatures.

Layer-2: Aluminum Foil is the barrier against water vapor transmission and aggressive greases.
Layer-3: An inner layer of low density polyethylene making the laminate capable of being heat sealed without degradation to the outer layer of polyester.
