The main role of pvc shrink film

PVC shrink film is one of the most widely used films at present. It is inexpensive, the temperature shortening scale is large, the demand for heat source is not high, the primary processing heat source is hot air, infrared or the link between the two. However, PVC is difficult to recycle,heat shrink film incineration produces toxic gases, is not conducive to environmental protection, in Europe, Japan has been banned from use. Shrink film compression fixity: with the help of the retraction force after the stretching of the winding film the product will be wrapped and packed, forming a compact. Not occupy space unit as a whole, so that the product pallets are tightly wrapped together, which can effectively prevent the products from being misplaced and moving each other during transportation, and at the same time, the adjustable stretching force can make the hard products tightly adhered and make the soft products tightly, especially in the tobacco industry as well as the textile industry, which has a unique packaging effect. Cost savings: the use of wrap-around film for product packaging, can effectively reduce the cost of using wrap-around film is only about 15% of the original box packaging, heat shrink filmabout 35%, about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve the packaging efficiency and packaging grade.

Heat shrink film is a new type of packaging material in line with the environmental requirements of the heat shrink film body, heat shrink film has high strength, rigidity, shape stability, and has a good gloss and transparency. Convenient processing, easy coloring, good printing performance, there is a very high printing resolution, for the continuous pursuit of beautifully printed trademark, is completely a material progress.

pvc shrink film is used in the sales and transportation process of various products. Its main function is to stabilize, cover and protect the product from scratches and scattering. Heat shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinkage process, the film must not produce holes, and the temperature must not be too high at the time of shrinkage, otherwise the surface temperature of the film will be too high to make its film break holes.
