What are the functions of vacuum bag and aluminum foil bag?
The functions of vacuum bag and aluminum foil bag include: With three/four-layer structure (PET/aluminum foil/ nylon/PE), aluminum foil bag is characterized by good water-proofness, moisture-proofness, anti-staticness, antijamming, high mechanical strength and heat sealability. It is specially suitable for anti-static and moisture-proof vacuum packaging of large-scale precise machinery and equipment, chemical raw materials, food and pharmaceutical products.
Aluminum foil bag usually refers to aluminum-plastic composite vacuum bag, suitable for moisture-proof and light-proof vacuum packaging of large-scale precise machinery and equipment, chemical raw materials and pharmaceutical intermediates. With four-layer structure, it is characterized by good water-proofness and oxygen isolation. Aluminum foil bag can be made into flat pocket style, three-dimensional bags, organ bags, etc, according to the requirements of customers. The test results of GB and ASTM show that the product complies with environmental requirements (a third party testing report available if required) and the environmental standard of EU and North America in which packing material is most strictly required.
Vacuum bag, also called close-fitting moisture-proof bag, aluminum foil bag, aluminum-plastic composite bag, adopts PET/AL/CPE or PET/NY/AL/CPE as its material. Among them, PET has good printing effect, NY low oxygen permeability, AL strong barrier property and light tightness and CPE double packing. Adhesive: Water-soluble adhesive (more sanitary, environmental with less liquid residue) is featured by good anti-staticness, oxygen isolation, shielding, moisture-proofness, opacity and heat sealability. The products can be reinforced with anti-static function, product description, company logo and anti-static marks with no changes of product performance according to the special requirements of users. It is suitable for electronics, communications, national defense in which vacuum packaging is required.
