Food vacuum packaging and vacuum inflatable flexible packaging applications - vacuum packaging, flex

Vacuum-packed main role is usually to deoxygenation, to support prevent food spoilage, the principle is simple, because of deterioration of food mold rot caused mainly by microbial activity, and a lot microorganisms (along the lines of mold and yeast) of survival need oxygen, and vacuum packaging would be the having access to this principle, the packaging bag and food cells lacking oxygen, in order that micro-organisms to get rid of "survival from the environment." Experimental results show: in case the packing bag of the oxygen concentration 1%, the microbial growth and reproduction rate with the sharp decline in oxygen concentration of 0.5%, a good number of micro-organisms can be inhibited stopped breeding. (Note: Vacuum packaging won't be able to inhibit the enzyme result of anaerobic bacteria to multiply and cause food spoilage and discoloration, it must integrate with some other complementary methods, such as refrigeration, freezing, dehydration, heat sterilization, irradiation sterilization, microwave sterilization, salt pickled, etc..) Vacuum oxygen removal together with inhibit microbial growth and reproduction, other important function is to prevent food oxidation, thanks to fats and oils in foods complete of unsaturated essential fatty acids, the role of oxidation by oxygen for making food than usual, and metamorphic. Aside from that, the oxide also makes a vitamin and ascorbic acid loss, food coloring becoming volatile substances by oxygen, so that the color darker. Therefore, deoxygenation can prevent food deterioration, maintaining its color, smell, taste and nutritional value. Inflatable vacuum packaging vacuum packaging major role aside from the oxygen removal with durability features, there is also the compressive strength, gas barrier, preservation role, can better make long-term to keep up the first food color, flavor , flavor, shape and nutritional value. In addition, many food not suitable for vacuum packaging, which ought to be vacuum packed inflatable. Fragile foods just like crisp,nfl store, easy caking of food, easy deformation of your oil away food, you will find sharply higher hardness of edges, or punctured bags of food. Inflated by vacuum packaging of food, the packaging bag filling pressure is greater than the external atmospheric pressure bag can effectively steer clear of the food being forced crushing distortion, has no effect on the style of bags and printed decoration. Inflatable packaging with a vacuum thereafter vacuum containing nitrogen, fractional co2, oxygen single gas or 2? Three types of gas mixture. That's inert nitrogen gas, from the filling, to ensure that bag not to lose positive pressure to not have outside air into your bag bags,mac makeup, food plays a protective role. And also carbon gas can dissolve in fats or water to build weak carbonic acid, to inhibit mold, bacteria, and corruption activity. Oxygen inhibits the development of anaerobic bacteria breeding, keeping fruits,mlb shop, vegetables and fresh color, high concentrations of oxygen can maintain its bright red of fresh meat. Vacuum packaging Cured products: sausage, ham, bacon, duck, etc.; pickled vegetables: mustard, dried radish, turnip, pickles, etc.; bean products: tofu, vegetarian chicken, red bean, etc.; cooked meals: chicken, duck, sauce beef; convenience food: rice, instant wet surface, ready food, etc.; soft canned: Shimizu bamboo shoots, canned fruit, eight-treasure porridge or anything else. Vacuum packed inflatable Tea, nuts, Guazi Ren, dried meat floss, etc.; fried casino chips, puffed food, fruit vegetables, chips, etc.; cakes, moon cake, etc.; all sorts of powder, food additives; an assortment of native, rare Chinese herbs; numerous dehydrated vegetables. Vacuum packaging or vacuum packaging used inflatable two or three times composite film made out of aluminum thin film composite triangular sealing bags, composite thin film thickness is by and large 60? 96 m, among how the inner layers for that sealing, needing a fantastic seal, thickness inside the 50? 80 m between outer sealing layer, needing good air tightness and printability, a small intensity, the thickness of the 10? 16 m between. Common polyethylene film inner layer composite substrate (PE), high heat cooking bags are used as hot temperatures polypropylene (CPP), oriented polypropylene outer layer base material used (OPP), polyester (PET), nylon (PA), etc. . Some foods such as tea, milk and many other high-fat food, stuffed with light resistance, to circumvent the impact of food by the light to modify color, smell and taste, and that is somewhere between the substrate and inner layer of very thin aluminum foil compound (AL), the actual environment tightness has additionally strengthened. Vacuum or vacuum packaging machine used inflatable cavity and also the outside pumping home equity loans models. Chamber vacuum packaging machine is divided inflatable vacuum packaging machine and packaging machine. Outside pumping vacuum packing machine possesses the inflatable packaging and vacuum packaging, and a lot of other functions, what are known as multi-functional modified atmosphere packaging machine. Buy packaging materials packaging machine as reported by the shape required, how large is packing capacity, production volume, the manner the place where a mixture of a few packaging the best consultation before purchasing. Food vacuum and vacuum inflatable flexible packaging technology, in food packaging technology occupies a precise position, some functions won't be replaced by other packaging. Our vacuum packaging technology in early 80s of 20th century developed, and vacuum packaging technology noisy . 90s of 20th century handful of use, aided by the small package of promotion and continuing development of the supermarket, its scope is often more widely, a few will gradually replace rigid packaging,mac makeup wholesale, the outlook is promising.
