Uses of food aluminum foil bags: Vacuum nylon bags are generally composite bags, that is, one, two or more base films (heat-sealed PE film, CPP, BOPP) and nylon (good airtight) or PET special glue through the film Adhesive (chemical product) is compounded into a film by a compound machine. Then it is made by a bag cutting machine, and the sealing performance after vacuuming is the best. Strong air barrier performance, anti-oxidation, waterproof, moisture-proof mechanical properties, high blast resistance, strong puncture and tear resistance, high temperature resistance (121 ° C), low temperature resistance (-50 ° C). Non-toxic, tasteless in line with national standards. Good heat sealing performance and good transparency. The first thing to consider for food bags is the barrier performance of the packaging material. Because the barrier property is good, the preservation time is long, the shelf life is long, and the quality can be better guaranteed.

At present, among all food packaging materials, aluminum foil has the best barrier property (followed by some high Molecular plastics, such as EVOH, PVDC, etc.) Therefore, the most common one is always to compound a layer of aluminum foil between two layers of plastic film to improve barrier properties. Aluminum foil bags are generally divided into pure aluminum bags and aluminum-coated bags, usually made of aluminum foil and special materials. Composite. Aluminum foil bags have high mechanical strength, good anti-static, anti-oxidation, moisture-proof and electrostatic shielding properties, excellent heat-sealing performance; environmental protection performance can meet international standards. Conventional thickness of aluminum foil bag: 80μm, 140μm, surface resistance: 108-10Ω, surface color: silvery white. Anti-static shielding bag Faraday electric cage structure, the average shielding barrier can reach 60db, strong electrostatic protection function, the inner layer is made of pure metal aluminum, the resistivity is lower than 0.1 ohm, and has good water, oxygen, light, and vacuum functions. Excellent anti-static function, yltpackaging food aluminum foil bags can slowly and safely discharge the electrostatic field, aluminum foil bags are widely used in electronic components, electrical appliances, food, cosmetics and other industries
