Abstract

The invention discloses a novel perspective film and a preparation method thereof. The perspective film comprises a transparent film layer and a glue layer. The glue layer is made of nontransparent aqueous pressure sensitive adhesive and hot melt pressure sensitive adhesive. Multiple round glue points with a same diameter are arranged in sequence to form a porous honeycomb shape. An anti-stickinglayer is arranged under the glue layer. The glue layer is prepared by steps of gravure, letterpress printing, and painting, which is carried out by a hot melting device. The production speed is quick,and the glue layer is very uniform. The glue layer is discontinuous, so the glue loss is low, moreover, the initial adhesion value of the glue layer is small, the glue layer can be adhered and peeledoff conveniently, and the problems of a hole containing mono-perspective film such as dislocation in adhering process, hole tearing, and the like, are avoided. The structure is simple, the process issimplified, the cost is low, and the perspective effect is also achieved.

Description

technical field [0001] The invention relates to the field of see-through films, in particular to a novel see-through film with a special adhesive layer and a preparation method thereof. Background technique [0002] The existing see-through film is divided into single-transparent film and double-transparent film. The so-called single-transparent film is glued on the back of the release paper, then laminated with PVC black and white film, then punched, and then the release paper with holes is replaced. Covered with a new release paper, it is produced by a series of processes. When in use, spray-paint on the inkjet surface of the PVC black and white film, peel off the release paper and stick it on the glass plate. This see-through film has a front display screen. The back side is completely visible, so it is called a single-transparent film. This kind of see-through film needs to punch holes and replace the release paper. The process is long and complicated, the production eff...
