Packaging professional custom vacuum food packaging bags

Vacuum packaging refers to the product to join the tightness packaging container, air drawn to the inside of the container, after making the seal of the container to the expected vacuum degree of a kind of packing method. Vacuum bag also called vacuum packaging, is take out all the air in the container seal, maintain bag at high stress state, the rare air of low oxygen effect, make no microorganisms living conditions, in order to achieve the purpose of fruit fresh, disease-free corrosion occurs. Application of a plastic bag vacuum packing, the aluminum foil packing, glassware, etc. Can choose according to item packaging materials. Because the fruit is fresh food, is still in the respiration, altitude hypoxia can cause physiological diseases, therefore, less fruit class use vacuum packing. Food vacuum packaging materials, the performance of a direct impact on the changes of the storage life of food and taste. In vacuum packing, choose good packaging material is the key to the success of packaging. Since when it comes to vacuum packaging materials, it is essential to the material classification, the following is suitable for vacuum packing of each material characteristics: the PE is suitable for the use of low temperature, RCPP is suitable for high temperature cooking makes; PA is to increase physical strength, durability performance; AL foil is to increase the blocking performance, shading; PET, increase mechanical strength and stiffness. Then according to the demand, combination, all kinds of performance, there are transparent, in order to increase the blocking performance using PVA water resistant high barrier coating. Advantages of high separation: using different high separation performance co-extrusion film, plastic material of oxygen, water, carbon dioxide, odor such as blocking effect. Stable performance, oil resistant, resistant to moisture, resistant to low temperature freezing, with good quality, fresh, odour, can be used for vacuum packing, aseptic packaging, inflatable packaging. Low cost: relative glass packaging, aluminum foil packing and other plastic packaging, to achieve the same barrier effect, co-extrusion film has great advantage on cost. Because of its simple process, the products of thin film production cost compared with the dry type composite film and other composite membrane can reduce 10 - 4, flexible specifications: 20% of different products can meet your different needs. High strength: co-extrusion film in the machining process has the characteristics of tensile, plastic stretch after corresponding improving strength, can also join in the middle of nylon, polyethylene and other plastic materials, give it more than general compound strength of plastic packaging, there is no hierarchical stripping phenomenon, good flexibility, excellent heat sealing performance. Capacity than smaller: co-extrusion film can be used in a vacuum shrinkable packaging, capacity volume ratio is near 100%, this is glass, cans, paper, incomparable. No pollution: don't add adhesives, no residue solvent pollution, green environmental protection. Vacuum packaging moistureproof, anti-static, explosion-proof and corrupt and insulation energy-saving + + single perspective + low cost + capacity than uv + + + high barrier effect from pollution.
