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

Vacuum-packed main role may be to deoxygenation, for helping prevent food spoilage, the principle is comparatively simple, resulting from deterioration of food mold rot caused mainly by microbial activity, a great number microorganisms (including mold and yeast) of survival need oxygen, and vacuum packaging will be use of this principle, the packaging bag and food cells missing out on oxygen, in order that micro-organisms reduce "survival of this environment." Experimental results show: the moment the packing bag with the oxygen concentration 1%, the microbial growth and reproduction rate of the sharp decline in oxygen power of 0.5%, the majority of micro-organisms will likely be inhibited stopped breeding. (Note: Vacuum packaging won't inhibit the enzyme reaction of anaerobic bacteria to multiply and cause food spoilage and discoloration, it has to integrate with many other complementary methods, including refrigeration, freezing, dehydration, heat sterilization, irradiation sterilization, microwave sterilization, salt pickled, etc..) Vacuum oxygen removal together with inhibit microbial growth and reproduction, the other one important function is almost always to prevent food oxidation, due to oils and fats in foods loaded with unsaturated fatty acids, the role of oxidation by oxygen to create food than normal, and metamorphic. Also, 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,mac makeup wholesale, taste and nutritional value. Inflatable vacuum packaging vacuum packaging big part in addition to the oxygen removal with durability features, there is the compressive strength, gas barrier, preservation role, can more effectively make long-term to hold the very first food color, flavor , flavor, shape and nutrients and vitamins. Aside from that, many food unsuitable for vacuum packaging, which need to be vacuum packed inflatable. Fragile foods just like crisp, easy caking of food, easy deformation for the oil away food, you'll see sharply higher hardness of edges, or punctured bags of food. Inflated by vacuum packaging of food, the packaging bag filling pressure is much more than the external atmospheric pressure bag can effectively stay away from the food under time limits crushing distortion, does not affect the perception of bags and printed decoration. Inflatable packaging in a vacuum then vacuum packed with nitrogen, carbon dioxide, oxygen single gas or 2? Three forms of gas mixture. Which can be inert nitrogen gas, within the filling, in order that bag to maintain positive pressure to avoid outside air in the bag bags, food plays a protective role. Skin tightening and gas can dissolve in fats or water to make weak carbonic acid, to inhibit mold,nfl store, 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 items: chicken, duck, sauce beef; convenience food: rice, instant wet surface, ready food, etc.; soft canned: Shimizu bamboo shoots, canned fruit, eight-treasure porridge etcetera. Vacuum packed inflatable Tea, nuts, Guazi Ren, dried meat floss, etc.; fried chips, puffed food, fruit vegetables, chips, etc.; cakes, moon cake, etc.; a lot of powder, food additives; an assortment of native, rare Chinese herbal supplements; a myriad of dehydrated vegetables. Vacuum packaging or vacuum packaging used inflatable two or three times composite film created from aluminum thin film composite triangular sealing bags, composite thin film thickness is usually 60? 96 m, among which the inner layers to your sealing, the requirement for a very good seal, thickness within the 50? 80 m involving the outer sealing layer, the desire for good air tightness and printability, a unique intensity, the thickness of your 10? 16 m between. Common polyethylene film inner layer composite substrate (PE), extreme temperature cooking bags are utilized as hot temperature polypropylene (CPP), oriented polypropylene outer layer base materials (OPP), polyester (PET), nylon (PA), etc. . Some foods which include tea, milk and certain other high-fat food, full of light resistance, to forestall the impact of food with the light to modify color, smell and taste, which is certainly amongst the substrate and inner layer of very thin aluminum foil compound (AL), the oxygen tightness has additionally been strengthened. Vacuum or vacuum packaging machine used inflatable cavity and also outside pumping 2 types of models. Chamber vacuum packaging machine is divided inflatable vacuum packaging machine and packaging machine. Outside pumping vacuum packing machine has got the inflatable packaging and vacuum packaging, many other functions, tend to be multi-functional modified atmosphere packaging machine. Buy packaging materials packaging machine as per the shape required, the magnitude of packing capacity,mac makeup, production volume, the way the place where a combined you should ensure packaging the ideal consultation before purchasing. Food vacuum and vacuum inflatable flexible packaging technology,mlb shop, in food packaging technology occupies an absolute position, some features and functions can not definitely be replaced by other packaging. Our vacuum packaging technology in early 80s of last century developed, and vacuum packaging technology noisy . 90s of last century a little use, using the small package of promotion and growth and development of the supermarket, its scope could be more widely, some will gradually replace rigid packaging, the outlook is promising.
