Copperplate synthetic paper special for thermal transfer and preparation method thereof

Abstract

The invention discloses a copperplate synthetic paper special for thermal transfer. The synthetic paper is composed of a 5-layer co-extruded structure, a core layer is a polypropylene calcium carbonate foam layer, the upper and lower layers of the core layer are white polypropylene layers, and the outer layers of the white polypropylene layer are respectively a modified functional polypropylene layer and a common polypropylene layer. The invention further provides a preparation method of the copperplate synthetic paper. The invention has the beneficial effects that the synthetic paper providedby the invention can fully adapt to various application requirements of thermal transfer ribbon printing, and has the thermal transfer ribbon printing performance of traditional synthetic paper, hasgood printing undertaking performance for ink printing after online corona treatment, can adapt to UV letterpress printing needs. A biaxial stretching process and a multi-layer co-extrusion BOPP modification technology are used to modify BOPP original films to achieve the application performance of synthetic paper, and since coating treatment is not required, a processing process for coating treatment of traditional synthetic paper is omitted, and thus a more economical low-cost synthetic paper surface material can be obtained.

Description

technical field [0001] The invention relates to the technical field of printing coated paper production, in particular to a special coated synthetic paper for thermal transfer printing and a preparation method thereof. Background technique [0002] At present, the traditional self-adhesive synthetic paper surface materials are all coated with biaxially oriented pearlescent synthetic paper materials with a specific gravity above 0.75. Due to the need for coating technology, biaxially oriented polypropylene film BOPP cannot be coated on-line, and must The off-line secondary processing of the completed materials increases the production cost of the materials. Contents of the invention [0003] The object of the present invention is to aim at the defects in the above-mentioned prior art, to provide a new type of low-cost synthetic paper self-adhesive surface material, that is, special coated synthetic paper for thermal transfer printing and its preparation method. Paper surfa...
