Cpp bottomless silent cold laminating film

Abstract

The invention provides a cpp bottomless silent cold laminating film, comprising: a non-silicon coating, a base film layer and a glue layer, wherein the non-silicon coating is applied on the front surface of the base film layer, one side, away from the front surface of the base film layer, of the non-silicon coating layer is protruded at intervals in a horizontal direction corresponding to the basefilm layer to form ribs, and the back surface of the base film layer is coated with aqueous glue to form the glue layer. During the use process, the tensile resistance of the base film layer can be enhanced by forming the ribs, so that the non-silicon coating is applied on the base film layer smoothly, the wrinkles are avoided, the generation of bubbles is reduced, and the efficiency of the coating is improved. The ribs form a texture, so that the three-dimensional feeling of the cold laminating film of the invention can be increased. A bottom paper layer is eliminated, so that the problems in the prior art that the unevenness of the bottom paper during the laminating process is likely to cause small bubbles in the film, shrinkage, film wrinkles, low speed, occupation of inventory space and the like can be avoided. Therefore, the cold laminating film is light, ultra-transparent, and more environmentally friendly, the production cost is reduced, and since water-based glue is used, thecold laminating film is safe, environmentally friendly, non-toxic and tasteless.

Description

technical field [0001] The invention belongs to the technical field of advertising materials, in particular to a CPP bottom-free silent cold lamination film. Background technique [0002] Cold lamination film is used for advertising materials such as wedding photos, oil painting pictures, calligraphy and paintings, outdoor posters, advertisements, various pictures, documents, materials, large-scale advertisements, architectural decoration renderings, background decorations, etc. [0003] The traditional cold lamination film is made of transparent PVC coated with oily glue and processed with a backing paper. However, PVC waste film and the backing paper peeled off during use cannot be recycled, resulting in a large waste of resources. The oily glue is not degradable, causing pollution to the environment and high production costs. The uneven backing paper during the lamination process may easily lead to small bubbles in the film. It is easy to shrink the edge, it is easy to f...

AI Technical Summary

Problems solved by technology

However, PVC waste film and the backing paper peeled off during use cannot be recycled, resulting in a large waste of resources. The oily glue is not degradable, causing pollution to the environment and high production costs. During the lamination process, the uneven bottom paper may easily lead to small bubbles in the film. Easy to shrink the edge, easy to wrinkle when passing the film, slow speed, occupying inventory space, etc.
