Abstract

The invention provides a surface touch pre-coated film and a preparation method thereof. The surface touch pre-coated film comprises a base material layer, a bonding layer and a touch layer, wherein the bonding layer and the touch layer are arranged on the surfaces of the two sides of the base material layer respectively, and the base material layer is a regenerated cellulose film subjected to polyethyleneimine anchoring treatment. The preparation method of the surface touch pre-coated film comprises a step of preparing the regenerated cellulose film subjected to polyethyleneimine anchoring treatment, namely a step of, in the preparation process of the regenerated cellulose film, adding polyethyleneimine into a softening bath to realize synchronous polyethyleneimine anchoring treatment inthe softening bath process to finally prepare the regenerated cellulose film subjected to polyethyleneimine anchoring treatment; a step of arranging the bonding layer, namely a step of arranging the bonding layer on any surface of the regenerated cellulose film subjected to polyethyleneimine anchoring treatment; and a step of arranging the touch layer, namely a step of arranging the touch layer onthe other surface of the regenerated cellulose film subjected to polyethyleneimine anchoring treatment. The pre-coated film can realize production flow optimization and guarantee coating adhesive force.

Description

technical field [0001] The invention belongs to the technical field of film coating of paper printed matter, and relates to a surface tactile pre-coating film and a preparation method thereof. Background technique [0002] In the field of paper printed matter lamination, there are instant coating film and pre-coating film. That is to say, the film coating is to directly coat the adhesive on the plastic film during lamination, and after drying online, it is bonded together with paper products by hot pressing to complete the lamination. The pre-coating film is a film-coating equipment that pre-coats the adhesive on the plastic film to make a pre-coating film base film, and then coats the functional coating off-line, and then dries and rolls it without an adhesive coating device. It is characterized in that it does not require an adhesive coating heating and drying system, which greatly simplifies the lamination process, is easy to operate, tasteless, has no solvent residue, a...
