Food vacuum packaging machine
Food vacuum packaging machine is composed of vacuum system, pumping and inflating sealing system, hot-pressing sealing system, electrical control system and so on. External pumping vacuum packaging machine is to automatically seal the packaging bag after it is pumped into low vacuum. Because of the high vacuum in the bag, the residual air is very little, which inhibits the reproduction of microorganisms such as bacteria, avoids the oxidation, mildew and corruption of the goods. At the same time, for some soft goods, the packaging can be reduced by automatic vacuum packaging machine. Volume, easy to transport and storage.
Vacuum packaging or vacuum inflatable packaging commonly used double-layer composite film or three-layer aluminum thin composite film made of three-side sealing packaging bags, the thickness of composite film is generally between 60-96UM, in which the inner layer is a thermal sealing layer, which requires good thermal sealing, thickness between 50-80um, outer layer is a sealing layer, which requires good air tightness and printability. Polyethylene (PE) is commonly used as the inner base material of composite film, such as high temperature cooking bag, high temperature resistant polypropylene (CPP), tensile polypropylene (OPP), polyester (PET), nylon (PA) and so on. Some foods such as tea, milk powder and some high-fat foods need to be used. Light-retardant packaging, in order to prevent food from changing color, aroma and taste due to the influence of light, is to compound an extremely thin layer of aluminum foil (AL) between the inner and outer substrates, and its air tightness is also strengthened.
Now there are many enterprises specializing in the production of food vacuum packaging bags. Customers can communicate with their technology when ordering, and order bags suitable for their products according to their own product characteristics.
