Abstract

The invention relates to the technical field of high molecular materials, in particular to a PP precoating film. The PP precoating film is formed through co-extrusion molding of three layers, including a first layer, a second layer and a core layer, and has the thickness of 10-30 microns; the first layer comprises the following raw material components in percent by weight: 85-92% of PP, 2-5% of ananti-adhesive agent and the balance of polycarbonate functional masterbatch; the first layer comprises the following raw material components in percent by weight: 85-92% of PP and 8-15% of an anti-adhesive agent; the core layer comprises the following raw material components in percent by weight: 95-97% of PP, 1-2% of an antistatic agent and the balance of a slip agent. Through reasonable designof the component of the anti-adhesive agent, the effect of strong adhesion between a product and a paper product is achieved; through reasonable design of processing technological parameters as well as the raw material components and the proportions of each layer, the product achieves waterproof, anti-fouling and wear-resistant protective effects on a printed product and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PP precoating film. Background technique [0002] Pre-coated film refers to the process of gluing and rewinding plastic film in advance, and then compounding it with paper prints. First, the pre-coating film processing factory applies the glue solution on the film according to the use specifications and format, and then rewinds it for the manufacturer to choose, and then compound it with the printed matter. [0003] The pre-coating film in the prior art mainly has poor adhesion, and cannot protect printed matter from waterproof, antifouling and wear resistance. Contents of the invention [0004] In order to solve the technical problems existing in the prior art, the present invention proposes a PP precoat film, which has good binding force with paper products. [0005] The technical solution of the present invention is: a PP pre-coating film, formed by three-layer...
