Also known as decompression vacuum packaging, is the main role of the vacuum bag is based on the principle that the atmospheric oxygen, in order to help prevent food spoilage or deterioration. Vacuum packaging is to food packaging bag and oxygen intracellular microorganisms deprived by pumping loss of "life" of the process. Vacuum food can prevent oxidation, the food does not taste deterioration to reduce the loss of vitamins A and C. Product description: 1. air barrier performance, oxidation resistance, waterproof, moisture-proof. 2. High mechanical properties, high blasting performance, 3. high temperature (121 ℃), low temperature (-50 ℃), oil, incense guaranteed performance. 4. Non-toxic, tasteless, with food, pharmaceutical packaging hygiene standards. 5. sealing performance, flexibility, good barrier properties. Vacuum structure is generally: PET / PE or PET / CPP also have three, four, in order to increase the texture of the material properties of anti-static vacuum bag, PET / PA / PE, PET / AL / CPP, PA / AL / CPP, PET / PA / AL / CPP vacuum packaging features: a packaging container excluded local air (oxygen) can effectively prevent food spoilage transformation. Can effectively prevent the exchange packing material content; 2 A barrier (air tightness) of the packaging material and excellent sealing technology and strict requirements. To prevent food weight loss, loss of taste, but also to prevent secondary pollution. Accelerate the heat conduction; three vacuum-packed container inside the gas has been ruled out. This can improve the thermal conductivity vacuum sterilization efficiency, but also to avoid heating sterilization, due to expansion of the gas leaving the containers to rupture. Each vacuum bag material characteristics: one, where PE for low temperature use, RCPP suitable for high temperature cooking use; two, PA is to increase physical strength, puncture resistance; three, AL foil in order to increase the barrier properties, shading; four, PET increase the mechanical strength of the bag, very sexual distinctions. Then according to the needs of the aluminum foil vacuum bag, in combination, a variety of properties, there are transparent, in order to increase the barrier properties of barrier coatings using water-PVA. Several types of vacuum complex: generally: PA / PE or PA / RCPP, PET / PE or PET / RCPP have three, four, in order to increase the texture of the material properties: PET / PA / PE, PET / AL / RCPP , PA / AL / RCPP PET / PA / AL / RCPP conductive vacuum bag, bags, provided by Weihai Weihai Fujingtang Fujingtang New Decoration Material Co., Ltd.
