Knowledge of Laminated Aluminum Foil Bag

Aluminum Foil Bag

Shenzhen Yongliantai Plastic Packing Co., Ltd. specializes in the production of laminated aluminum foil bags, so in this article, we will analyze some basic knowledge of aluminum foil bags for you.

The aluminum foil bag we usually refer to is made of aluminum and other high-barrier materials after laminating. Aluminum has luster, strong reverse ability, good barrier property, airtightness, high temperature resistance, low temperature deformation, moisture resistance, and strong temperature adaptability. Therefore, the aluminum foil bags that are often compounded also inherit some of the characteristics of aluminum, and have the functions of avoiding light, blocking, and anti-static, and can also achieve vacuuming.

1.The applicationof laminated aluminum foil bags:

A: Food packaging: such as packaging meat products, dried fish, aquatic products, preserved meat, roast duck, roast chicken, roast pig, quick-frozen food, ham, cured meat products, sausages, cooked meat products, pickles, bean paste, seasonings, etc. Preservation of fragrance, quality, taste and color. The water vapor transmission rate can reach <0.015 g/(m2/24h)>, and it also has the function of heat sealing. It can be vacuum-packed. The appearance of the laminated aluminum foil bag is opaque, silver-white, and has anti-gloss. , stored in an environment with a humidity of ≤90%.

B:Electronic product packaging: such as mobile phone shielding bags, anti-static shielding bags, LED product packaging bags, etc. are all made of aluminum foil materials.

C: Packaging of pharmaceutical products: pharmaceutical products need to be protected from light and anti-oxidation. Therefore, the use of aluminum foil material is also the best material.

D: Cosmetic packaging and other aspects of daily life.

Aluminum Foil Bag

Composite type of composite aluminum foil bag:

A. Material: PET/NY/AL/PE (general packaging) PET/NY/AL/CPP (high temperature cooking); VMPET/CPE or PET/AL/NY/CPE (anti-static shielding bag)

B. Thickness: 70 ~ 180 microns: generally customized according to customer requirements

C. Bag shape: three-side seal, self-supporting zipper bag, yin-yang bag, middle-sealed organ
