Abstract

The invention discloses a BOPP matting transfer film for coating transfer. The BOPP matting transfer film for coating transfer sequentially comprises an upper surface layer, an upper core layer, a lower core layer and a lower surface layer, wherein the upper surface layer is an anti-adhesive layer; the upper core layer is a polypropylene layer; both the lower core layer and the lower surface layerare transfer layers; each transfer layer comprises the following components in percent by weight: 80-88% of matting transfer masterbatch, 4.0-8.0% of an antistatic agent, 4.0-6.0% of a slipping agentand 4.0-6.0% of an anti-adhesion agent. The BOPP matting transfer film is directly prepared by a four-layer coextrusion and biaxial stretching method. The BOPP matting film for coating transfer is uniform in matting layer surface roughness, stable in matting effect and good in transfer effect, and can be applied to transfer of leather textiles.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a BOPP matting transfer film for coating transfer and a preparation method thereof. technical background [0002] The transfer film is an intermediate carrier that exists on the transfer paper base or plastic base, carrying the printed or printed pattern, and is used to transfer to a layer of chemical elastic film on the printed article. Widely used in advertising, decoration, leather, textiles and other fields. [0003] At present, most of the BOPP transfer films on the market are glossy film transfer films, but in recent years, more and more products require a matte effect to reduce the gloss of the pattern. At present, the main process is to use a light film type transfer film to transfer and then apply a matting agent to achieve a matting effect. Contents of the invention [0004] Aiming at the deficiencies of the above-mentioned prior art, the object of the present inventi...
