Abstract

The invention discloses a plastic packaging film. The plastic packaging film comprises a base layer, and is characterized by further comprising a peeling layer, an adsorption layer and a writing layer, wherein the adsorption layer and the peeling layer sequentially cover one side of the base layer; the writing layer covers the other side of the base layer; the peeling layer is 10 [mu]m to 15 [mu]m in thickness; the adsorption layer is 5 [mu]m to 10 [mu]m in thickness; the base layer is 15 [mu]m to 20 [mu]m in thickness; and the writing layer is 10 [mu]m to 15 [mu]m in thickness. According to the invention, the plastic packaging film can adhere to the outer side of an arbitrary packaging box, information of a product inside the packaging box can be written and marked through a fountain pen, the plastic packaging film is utilized for multiple times, the price is low, and popularization is facilitated.

Description

technical field [0001] The invention relates to a packaging film. Background technique [0002] With the development of society, almost all products have packaging boxes. Once the products are put into the packaging box, it is troublesome to reopen them. Therefore, in the process of use, the user generally first judges the product contained in the box from the appearance of the packaging box, and then opens the packaging box to take out the desired product. However, it is difficult to judge the content of the conventional packaging box by its appearance, so a packaging film is needed, which can be attached to the outside of the packaging box and can clearly display the products in the packaging box. Contents of the invention [0003] The invention aims at the existing deficiencies and provides a plastic packaging film which can be attached to the outside of the packaging box and can clearly display the products in the packaging box. In order to achieve the above object, ...
