Foil Barrier Packaging

Aluminum-plastic composite bag is made of high barrier polymer modified PE composite

Aluminum-plastic composite barrier bag is the most recent invention in heavy-duty packaging; it is made by laminating plastic film with aluminum to form bags that are moisture-proof, leak-proof, and prevent any light from seeping through. These bags enable for nicely printed exteriors to produce a high-quality packaging impression. They also enable for one-way degassing and vacuuming, which is highly recommended for materials that cannot be exposed to moisture and high-value items.

Product Feature

Aluminum-plastic composite bag is made of high barrier polymer modified PE composite, moisture-proof effect is 80 times of ordinary polyethylene, has good protective performance: oxygen resistance, moisture-proof, puncture resistance, high strength, high toughness, one-way or two-way breathable, strong ultraviolet resistance, chemical resistance, oil resistance and acid and alkaline substances; Suitable for containing 20kg to 50kg, powder materials, engineering plastics, chemical raw materials, dyes, pigments, animal feed, various additives.


Composition:usually consists of three to four layers or multiple layers of adhesive laminated together to form a composite film.

The first layer: the surface layer can ensure the strength and puncture resistance of the bag at a certain temperature and within a certain range.

The second layer: aluminum foil, barrier layer. The main role is to prevent moisture, oxygen and light.

The third layer: the innermost layer is the heat seal layer.
