Problems solved by technology

[0003] After the existing transparent decorative film is pasted, because one side of the edge is an open area, it is easy to lift up when there is water vapor or dust, and the entire decorative film will gradually fall off after a long time. Moreover, it is easy to be pulled, deformed or scratched. This is the disadvantage of the current decorative film, and there is no good solution

Abstract

The invention discloses an edge self-sealing type transparent PVC film and a preparation method thereof, and belongs to the technical field of PVC film edge sealing. The edge self-sealing type transparent PVC film comprises a PVC film body, wherein the PVC film body is divided into a packaging area and edge sealing areas, the edge sealing areas are located on the two sides of the packaging area, areinforcing strip is pressed in the middle of the packaging area, and firm edge sealing of the PVC film packaging bag can be achieved. Two hot-pressing sealing edges are arranged, so that the sealingedges are prevented from cracking; a reinforcing strip is additionally arranged at the bottom to reinforce the strength of the bottom, so bottom cracking caused by insufficient bearing force is avoided; during hot pressing, the folded PVC film is pressed by a pressing plate, the two sides of the PVC film are exposed, hot-pressing edge sealing of a hot-pressing roller is facilitated, and meanwhile, the upper layer PVC film and the lower layer PVC film can be prevented from moving in a staggered mode; and taking and placing of the pressing plate are achieved through an automatic mechanical structure, so the labor intensity of workers is reduced, the cost investment is reduced, and the productivity can be improved.

Description

technical field [0001] The invention relates to the field of decorative films, in particular to an edge self-sealing transparent PVC film and a preparation method thereof. Background technique [0002] Decorative film is a new type of decorative material made of high molecular polymer (PVC), adding various additives, calendering and compounding. It can be compounded with wood, plastic board, aluminum board, iron board and other substrates. As a multi-purpose decorative material, it is widely used in household appliances, audio surface decoration, interior decoration, interior decoration of aircraft, ships and trains. In addition, it can also be used for billboards, etc. [0003] After the existing transparent decorative film is pasted, because one side of the edge is an open area, it is easy to lift up when there is water vapor or dust, and the entire decorative film will gradually fall off after a long time. Moreover, it is also easy to be pulled, deformed or scratched. T...
