Features and main functions of vacuum bags

Vacuum bag: Its material is generally NY (PA)/CPE or PET/NY (PA)/. Plastic bag film is milky white, translucent (several layers stacked up to observe especially obvious), feel more lubricated, as if the surface is coated with a wax layer, shaking with force, the sound of brittle, flammable in case of fire, the flame is yellow, burning mucus drips, and there is an odor of burning candles. Food bag shell can make the food and oxygen, water vapor, stains, etc. separated, leakage prevention is also a necessary factor in packaging design. Some packages include desiccants or deoxidizers to extend shelf life. Vacuum packaging or evacuation of air from the bag is also a major food packaging method. Preserving the cleanliness, freshness and safety of food during its shelf life is the primary function of the bag. Automatic packaging roll film is a special packaging material for automatic packaging machine, because the use of this packaging material is more efficient than the bag packaging, therefore, it is used and marketed more and more high. This product has anti-static function, good vacuum effect, high transparency, low oxygen permeability, good moisture resistance, high tensile strength and puncture resistance, easy to heat-seal, good sealing performance, not easy to aging and other characteristics, mainly used for hardware, electronic components, the need for vacuum packaging. Size, specification, high temperature resistance, etc. can be customized according to needs. We can also print text, patterns, trademarks, etc. according to customer requirements, without infringing on the intellectual property rights of others, to help you enhance your corporate image.

Nylon vacuum bag, also known as decompression bag, the air in the packaging container is completely extracted and sealed, in the maintenance of the bag in a high-pressure - decompression state, the air is less than the low-oxygen effect, so that microorganisms have no conditions for survival, so as to achieve the purpose of the fruit fresh and disease-free. Taizhou vacuum bag is currently applied to plastic bags, such as vacuum packaging, aluminum foil packaging, glassware packaging. Packaging materials can be selected according to the type of items. Because the fruit belongs to the fresh food, is still in the respiratory function, oxygen height will cause physiological diseases, therefore, the fruit class use vacuum packaging is less, vacuum packaging principle is very simple. The main cause of food corruption is the activity of microorganisms, microorganisms (such as molds and yeasts) need oxygen to survive, vacuum packaging is the application of this principle, extracting the bag and the food cells in the oxygen, thus depriving microorganisms of their living environment. At the same time, it prevents food from changing taste and deterioration due to oxidation, thus achieving the effect of long-term storage and preservation of food.
