Vacuum-packed main role is to deoxygenation, to help prevent food spoilage, the principle is comparatively simple, stemming from deterioration of food mold rot caused mainly by microbial activity, a great number microorganisms (that include mold and yeast) of survival need oxygen, and vacuum packaging would be the using of this principle, the packaging bag and food cells who don't have oxygen, to make certain that micro-organisms to give up "survival of your environment." Experimental results show: in the event the packing bag of this oxygen concentration 1%, the microbial growth and reproduction rate with the sharp decline in oxygen concentration of 0.5%, virtually all micro-organisms is going to be inhibited stopped breeding. (Note: Vacuum packaging can not inhibit the enzyme reaction of anaerobic bacteria to multiply and cause food spoilage and discoloration, it must integrate with complementary methods, just like refrigeration, freezing, dehydration, heat sterilization, irradiation sterilization, microwave sterilization, salt pickled, etc..)
Vacuum oxygen removal along with inhibit microbial growth and reproduction, the additional important function would be to prevent food oxidation,
mac makeup wholesale, as a consequence of oils and fats in foods loaded in unsaturated fatty acids, the role of oxidation by oxygen to earn food than normal, and metamorphic. Furthermore, the oxide also makes vit a and vit c loss, food coloring in the role of volatile substances by oxygen, to ensure the color darker. Therefore, deoxygenation can prevent food deterioration, maintaining its color, smell, taste and nutrients and vitamins.
Inflatable vacuum packaging vacuum packaging big part much better oxygen removal with durability features, there's also the compressive strength, gas barrier, preservation role, can more effectively make long-term to help keep the actual food color, flavor , flavor, shape and vitamins and minerals. On top of that, many food not suitable for vacuum packaging, which needs to be vacuum packed inflatable. Fragile foods along the lines of crisp, easy caking of food, easy deformation with the oil away food, you will see sharply higher hardness of edges, or punctured bags of food. Inflated by vacuum packaging of food, the packaging bag filling pressure is bigger than the external atmospheric pressure bag can effectively stay away from the food pressurized crushing distortion, has no effect on the perception of bags and printed decoration.
Inflatable packaging at a vacuum and be able to vacuum loaded with nitrogen, co2 fractional laser, oxygen single gas or 2? Three sorts of gas mixture. Which is certainly inert nitrogen gas, from the filling, to make sure bag to look after positive pressure to halt outside air to the bag bags, food plays a protective role. As well as gas can dissolve in fats or water to generate weak carbonic acid, to inhibit mold, bacteria, and corruption activity. Oxygen inhibits the rise of anaerobic bacteria breeding, keeping fruits, 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 food: chicken, duck, sauce beef; convenience food: rice, instant wet surface, ready food, etc.; soft canned: Shimizu bamboo shoots, canned fruit,
mac brushes, eight-treasure porridge and many others.
Vacuum packed inflatable Tea, nuts, Guazi Ren, dried meat floss, etc.; fried poker chips, puffed food, fruit vegetables, chips, etc.; cakes, moon cake, etc.; all sorts of powder, food additives; several native, rare Chinese herbal supplements; heaps of different dehydrated vegetables.
Vacuum packaging or vacuum packaging used inflatable two or three times composite film produced from aluminum thin film composite triangular sealing bags, composite thin film thickness is usually 60? 96 m, among which the inner layers for the sealing, the demand for a fantastic seal, thickness on the 50? 80 m between your outer sealing layer, the demand for good air tightness and printability, a small intensity, the thickness from the 10? 16 m between. Common polyethylene film inner layer composite substrate (PE), extreme temperature cooking bags utilized as hot temperatures polypropylene (CPP), oriented polypropylene outer layer base materials (OPP), polyester (PET), nylon (PA), etc. . Some foods including tea, milk as well as some other high-fat food, brimming with light resistance, to avoid the impact of food by light to move color, smell and taste, that may be among the substrate and inner layer of very thin aluminum foil compound (AL), the oxygen tightness has been strengthened.
Vacuum or vacuum packaging machine used inflatable cavity together with the outside pumping 2 kinds of models. Chamber vacuum packaging machine is split inflatable vacuum packaging machine and packaging machine. Outside pumping vacuum packing machine offers the inflatable packaging and vacuum packaging,
canucks store, and a few other functions, myteriously named multi-functional modified atmosphere packaging machine. Buy packaging materials packaging machine based on the shape required, how big packing capacity, production volume,
insanity vs p90x, the manner where a blend of considerations packaging the top consultation before purchasing.
Food vacuum and vacuum inflatable flexible packaging technology, in food packaging technology occupies an apparent position, some features simply cannot simply be replaced by other packaging. Our vacuum packaging technology noisy . 80s of last century developed, and vacuum packaging technology during the early 90s of 20th century hardly any use, with all the small package of promotion and healthy the supermarket, its scope is more widely, a few will gradually replace rigid packaging, the outlook is promising.
