We understand that the overwrapping machine and shrink wrapping machine seem to be plastic film packaging, easy to be confused in the choice of packaging machine, the following to introduce the difference between the two, and briefly introduce the advantages of overwrapping machine and shrink wrapping machine.
Overwrapping machine, also known as transparent film overwrapping machine, cigarette packing machine, transparent film hexahedron folding cold packaging machine, transparent film packaging machine. This machine takes BOPP film or PVC as the packing material, and will be packaged into a three-dimensional hexahedron folding packaging equipment. Overwrapping machine was first introduced from abroad, after continuous improvement by domestic enterprises to make it meet the domestic market, now there are manual, semi-automatic, automatic models, and single box packaging and set box packaging. Overwrapping machine is widely used in medicine, health care products, food, cosmetics, stationery, audio-visual products and other industries in a variety of box-type goods single automatic packaging. For example, for boxed medicine, food, cards, sticky notes, tapes, waffles, etc.
Shrink wrapping machine is to the product packaging set a layer of film to play a beautiful role. It is mainly through the shrinkage film heating, so that the shrinkage film tightly fit on the product. Through the product packaging, to achieve the purpose of moisture-proof, dustproof and waterproof, but also can make the product look beautiful and generous. Suitable for glass bottles, foam, paper boxes, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, drugs, cosmetics, drinks, fruits, commemorative labels and other items packaging.
Because overwrapping machine without the heating stove as shrink wrapping machine will heat the whole product, and the local point instant low temperature sealing will not make the temperature change of the package in the box, so it is called cold press. In the packaging of boxed products, the first use of cutting knife to cut the packaging film into the length suitable for the package, and then according to the set (through the human-machine interface) good quantity specifications through the cylinder to promote the technology of product stacking, will eventually stack good products for hexahedral folding packaging, can replace the shrink wrapping machine. It can save energy and electricity than shrink wrapping machine, fully sealed packaging: waterproof, moisture-proof, anti-infection.
