Wujiang food foil bags are produced after the dry compound with other materials into high barrier foil bags of products based on the unique properties of aluminum aluminum. Shiny aluminum due to light, the reverse ability, good barrier, impermeable to gas and water vapor, temperature adaptability, high temperature or low temperature stable shape, shading and strong aroma preservation excellent characteristics, so foil bag Good moisture barrier, blocking, light, resistance to penetration and aesthetically pleasing features, water vapor transmission rate of up to, but also a heat-sealing function, can be vacuum packaging, aluminum foil bags look opaque, silver-white, counter-gloss, can ≤ 38 ℃ in temperature, humidity ≤90% of the storage environment. Aluminum foil bags used in food packaging, usually used for packaging meat products, dried fish, aquatic products, sausages, duck, chicken, pork, frozen food, ham, bacon products, sausages, cooked meat, pickles, bean paste, spices, etc. Paul Hong, quality, flavor, color retention. Packaging weight reduction will continue to make progress. From some of these projects can be clearly seen in the general trend to reduce packaging quality. Smaller weight plastic containers and flexible packaging, plastic bottles instead of glass and metal containers, can reduce the amplitude of ground transportation costs. Its development trend include: easy to pick up handling, required inventory that due to lighter packaging, pallet load is reduced accordingly, may reduce the spleen motorcycle and fork lifts; for the individual cartons, glass and plastic containers, and flexible packaging other food packaging container packing up, we need to increase their strength, in order to facilitate safe delivery of the store.
