What is the main purpose of the pneumatic vacuum packaging machine?

The main functions of the vacuum packing in addition to oxygen and quality assurance, also has the function such as compression, gas resistance, save. Small with a heat pumping air into vacuum state, sealing, cooling the one-time completed function, apply to food, aquatic products, chemical raw materials, electronic components, precision parts and other products of vacuum sealing, can prevent oxidation, mildew, corrosion, moisture, but also extend the product with good quality fresh storage life of the machine. It can more effectively to keep food original color, aroma, taste, shape and nutritional value. In addition, many food doesn't suit, must use vacuum packing machines, vacuum packing. Such as food walking crispy, easy to agglomerate, easy to deformation and oils, with a sharp edge or high hardness will penetrate food packaging bags, etc.

food vacuum packaging, packaging bags inside air pressure is higher than the atmospheric pressure outside the packet, which can effectively prevent food extrusion deformation under pressure, and does not affect the appearance of the packaging and decoration printing. After vacuum packaging vacuum, and then fill the nitrogen, carbon dioxide, oxygen, or a single gas or a mixture of two or three kinds of gas. The nitrogen is inert gas, filling effect, make the bag to maintain positive pressure, in order to prevent the outside air into the bag, bag of food protection. The carbon dioxide can dissolve in various kinds of fat or water, weak acid, carbonate, corruption has inhibitory activity of bacteria and other microorganisms. Its oxygen can inhibit the growth of anaerobic bacteria and reproduction, keep the fresh degree of the fruits and vegetables and colour and lustre, high concentration of oxygen can keep fresh red.

vacuum packaging specification

1, high barrier property: adopt different plastic co-extrusion film material high separation performance, achieve oxygen, water, carbon dioxide, high barrier effect.

2, stable performance, oil resistant, resistant to moisture, resistant to low temperature freezing, quality preservation, odor preservation, can be used in vacuum packaging, aseptic packaging, plastic packaging.

3, low cost, compared with the glass packing, the aluminum foil packing, such as plastic packaging, to achieve the same barrier effect, co-extrusion film has great cost advantage. Because of its simple process, compared with the dry type composite membrane and other composite membrane, membrane can reduce 10% ~ 20%, the cost of the product specifications and flexible, can meet the different needs of different products.

　　5. High strength: co-extrusion film has the stretchability in the machining process. After stretching can improve the strength of the plastic, accordingly can also join in the middle of nylon, polyethylene and other plastic material, make its have the compound strength is higher than common plastic packing, no layering stripping phenomenon, good flexibility, heat sealing performance.

6, volume small, co-extrusion film by vacuum, volume ratio of close to 100%, is can't be matched by glass, cans, paper.

7, no pollution, no binder, no residual solvent pollution, green environmental protection. Take out of air inside the bag, to the expected after vacuum degree, complete sealing process. Is used widely in food industry, vacuum packaging, all kinds of cooked products, such as chicken, ham, sausages, grilled fillet, beef jerky, etc; Pickled products such as all kinds of pickled vegetables and soy products, dried fruit, etc are used more and more various need fresh food vacuum packaging. After vacuum packaging of food freshness long, greatly extend the shelf life of food.
