High-barrier laser transfer paper

High-barrier laser transfer paper is provided. One or any of a back coating layer, a glue layer, a transfer paint layer and a varnish layer are replaced completely or partially with high-barrier paper and PVDC (polyvinyl dichloride) emulsion, the high-barrier paper is made via the PVDC emulsion from the following materials in percent by weight: 60-90% of PVDC emulsion, 2-10% of acrylate monomer, and 8-30% of polyurethane prepolymer. One or any of coating materials for existing laser transfer cards are replaced completely or partially with PVCD using safety environment-friendly paper, so that laser packaging paper has good moisture-proof and moistness-maintaining effects and can keep moisture in package constant. The high-barrier paper used herein uses PVDC emulsion and is modified via grafting and introduced polyurethane, film-forming property of PVDC emulsion and crystal completeness are greatly improved, and the PVDC is enabled to form in paper, a high-compactness high-crystal coating layer, thus improving barrier performance of the paper.
