Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static bags and other packaging materials, metal. 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 several common characteristics of high-temperature vacuum bag cooking bag, vacuum packaging for a variety of meats cooked food, easy to use, and health. Material: NY / PE, NY / AL / RCPP, NY / PE Features: moisture, temperature, shading, aroma, robust application: high-temperature sterilization of food, ham, curry, eel, grilled fish and gravy products. Vacuum packaging currently the most used primarily film material, of course, but also the use of bottled and canned. Food vacuum packaging film material to be used, to ensure that the packaging effect, aesthetic, economic and other aspects of a variety of foods to achieve the best condition. Meanwhile, food vacuum packaging for light resistance and stability of the material also have higher requirements. When a material alone can not meet these requirements, the package will tend to a combination of a variety of different materials together. The main role of the role of the vacuum bag vacuum bag is oxygen, in order to help prevent food spoilage, the principle is relatively simple, mainly because of deterioration of food mold rot caused by microbial activity, but most microorganisms (such as yeast and mold) of need oxygen to survive, but the principle is the use of vacuum packaging, the packaging bag and food cells deprived of oxygen, so that the micro-material objects lose the "survival of the environment." Experimental results show: When the oxygen concentration packaging bags ≤1%, rate of growth and reproduction of microorganisms on a sharp decline in oxygen concentration ≤0.5%, most microorganisms will be inhibited and stop breeding. (Note: The vacuum packaging can not inhibit the propagation of food spoilage and discoloration caused by anaerobic bacteria and enzyme reactions, and therefore needs to be combined with other auxiliary methods, such as refrigerated, frozen, dehydrated, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt marinated, etc.) ?? vacuum oxygen in addition to inhibit microbial growth and reproduction, another important function is to prevent food oxidation, because fats and oils in foods rich in unsaturated fatty acids, the role of oxygen by oxidation, the food taste, metamorphism, in addition, an oxidation of vitamin A and C losses, the role of oxygen in food coloring by unstable substances, the color darker. Therefore, the oxygen can effectively prevent food spoilage, keep its color, smell, taste and nutritional value. The main role of the vacuum inflatable packaging vacuum packaging in addition to possess oxygen durability features, there is also the role of compression, gas barrier, preservation, etc., can make food more effectively long-term to maintain the original color, smell, taste, shape and nutritional value. In addition, there are many foods are not suitable for vacuum packaging must vacuum inflatable packaging. Such as crispy or crunchy foods, caking food, easy to deform away food oil, sharp edges or high hardness will pierce the bag food. After filling the vacuum food packaging, packaging bag inflatable bag outside pressure greater than atmospheric pressure, can effectively prevent the food does not affect the compressive deformation broken bags appearance and printing and decorating. ?? Vacuum inflatable packaging in a vacuum and then filled with nitrogen, carbon dioxide, oxygen gas or a mixed gas of two single three gases. Its nitrogen is an inert gas, from the filling to make the bag to maintain a positive pressure to prevent outside air from entering the bag bag, food plays a protective role. Its carbon dioxide can dissolve in various types of fat or water, citing weak acidic carbonated, inhibit mold, bacteria and other microbial activity. Its oxygen inhibits the growth of anaerobic bacteria breeding, keep fruits and vegetables fresh and color, high concentrations of oxygen can maintain its bright red fresh meat. Use vacuum bags feature Description 1, barrier: the use of different barrier properties of plastic materials co-extruded film, to oxygen, water, carbon dioxide, odor barrier effect. 2, stable performance: oil resistance, moisture resistance, low temperature freezer, shelf, preservation, security odor, can be used for vacuum packaging, aseptic packaging, inflatable packaging. 3. Low cost: the relative glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, co-extruded film has a large advantage in terms of cost. As the process is simple, the production cost of the product and the dry film composite films and other composite film can reduce 10-20% compared to 4, specifications and flexible: you can reach the different needs of different products. 5, high strength: co-extruded film having a tensile characteristics in the process, after the plastic can be a corresponding increase in tensile strength, may be added as nylon, polyethylene and other plastic materials in the middle, it has more than the general strength of the composite plastic packaging There is no delamination phenomenon, softness, excellent sealing performance. 6, the capacity ratio is small: co-extruded film can be vacuum shrink packaging capacity volume ratio close to 100%, which is glass, cans, paper packaging can not match. 7, clean: do not add binders, no residual solvent pollution, green. Vacuum bags moisture + anti-static anti-bao + + + insulation corrosion of individual perspective + + + energy efficiency across the low cost UV + + + pollution + capacity than the small barrier effect.
