Preparation technology of anti-counterfeit package material through cold transfer film method

一种冷转移膜法制备防伪包装材料工艺

Abstract

The invention discloses a preparation technology of an anti-counterfeit package material through a cold transfer film method. The preparation technology comprises the following steps: painting a laser transfer paint on a PET film, drying; mould-pressing the PET film coated by the laser transfer paint by a mould pressing machine to obtain a laser film; washing the smooth surface of an aluminum foil by a mixed solvent, which is composed of ethanol and acetone according to a volume ratio of 3-8:1, drying the aluminum foil in a baking oven, painting a glue layer on the aluminum foil, immediately adhering the laser film on the glue layer of the aluminum foil, transferring the aluminum foil to a cold press roller to carry out cold pressing combination; after cold pressing combination, allowing the aluminum foil to stand still at a room temperature, peeling off the PET film to obtain a primary product of laser material, and laminating an outer protective layer on the laser anti-counterfeit layer of the primary product to obtain the laser material product. Cold transfer film method is adopted, the laser anti-counterfeit layer and aluminum foil are combined together, before combination, the aluminum foil is clean to remove the impurities so as to guarantee the product quality, and the obtained product has the advantages of stable structure, high yield, high surface quality, and low damage rate.
本发明公开一种冷转移膜法制备防伪包装材料工艺,包括以下步骤:将镭射转移涂料在PET薄膜上,然后烘干;采用模压机对涂布镭射转移涂料的PET薄膜进行模压,得到镭射膜;采用体积比为3~8:1的乙醇和丙酮的混合溶剂对铝箔纸光面层进行清洗,经烘箱烘干后涂布胶层,并立即将镭射膜贴附于所述铝箔的涂胶面,送入冷压辊下进行冷压复合;冷压复合后在室温条件下静置,并同时将PET薄膜揭掉,得到镭射材料初产品;在镭射材料初产品的镭射防伪层上复合外防护层,得到镭射材料产品。本发明采用冷转移膜法,将镭射防伪层与铝箔纸层复合,并且在复合前对铝箔纸进行清洁,避免杂物影响产品质量,得到的产品结构稳定,成品率高,且产品表面质量高,受损率低。
