Description

TECHNICAL FIELD

[0001] The utility model relates to stationery technical field, concretely is a kind of antistatic self-adhesive book film. BACKGROUND

[0002] With the diversification of educational supplies and the popularization of environmental protection concept, as a kind of commonly used material for protecting book cover, the market demand of self-adhesive book film continues to grow. The traditional self-adhesive book film is usually composed of a self-adhesive layer, a base material layer and a release layer, wherein the release layer is usually made of release paper as a substrate. However, the release paper has significant defects in practical application. On the one hand, the raw material of the release paper mainly depends on wood pulp or synthetic fiber, which has high energy consumption and is not biodegradable, and is not green and environmentally friendly. On the other hand, the mechanical strength of the release paper is low, and it is easy to tear or delaminate during cutting or use, resulting in curling of the edge of the book film or exposure of the adhesive layer. In addition, the use of release paper leads to wrinkles in the book film, affecting the use experience.

[0003] Moreover, the current self-adhesive book film also lacks functional design, and the common problem is poor antistatic property. In dry environment, the book film is easy to attract dust due to static electricity, which not only affects the appearance, but also affects the adhesion of the adhesive layer due to dust particles, resulting in poor adhesion.

[0004] Based on the above problems, there is an urgent need for an antistatic self-adhesive book film. SUMMARY
