The process of realizing the second transfer of opp transfer film

Abstract

The invention in particular relates to a technology for realizing secondary transferring of an OPP (oriented polypropylene) transfer membrane. The technology for realizing the secondary transferring of the OPP transfer membrane is characterized by comprising the following steps: 1) preparing a release layer liquid, namely diluting esterquats with ethyl alcohol to obtain the release layer liquid with the concentration of 0.2-1.5%, wherein the free acid alkalinity of the release layer is less than or equal to 5mgKOH / g, and the volatile component is 50+ / -3%; 2) coating, namely coating the surface of a used OPP transfer membrane with the release layer liquid by utilizing a coating machine and a roller; 3) drying, namely drying the OPP transfer membrane coated with the release layer liquid in a drying oven, so as to form a release layer on the surface of the OPP transfer membrane, wherein temperatures of the drying oven in 1-5 stage are 50 DEG C, 50 DEG C, 50 DEG C, 50 DEG C and 50 DEG C respectively; and 4) curing, namely standing and curing for 5 hours at room temperature. The technology for realizing the secondary transferring of the OPP transfer membrane has the advantages of simplicity and quick and convenient operation; and by adopting the technology for realizing the secondary transferring of the OPP transfer membrane, the used OPP transfer membrane can be transferred again, and product cost is greatly reduced for an enterprise.

Description

technical field

[0001] The invention specifically relates to a process for realizing the secondary transfer of an OPP transfer film. Background technique

[0002] The OPP transfer film is mainly used as a carrier for vacuum aluminum plating, that is, after the OPP transfer film is placed in a vacuum aluminum plating machine, it is coated with glue and combined with paper, and then the OPP transfer film is peeled off, and the aluminum molecular layer is transferred to the On the cardboard surface, the so-called aluminized cardboard is formed. The OPP transfer film achieves the above functions mainly because there is a release layer on its surface. The traditional OPP transfer film is a disposable product. After the OPP transfer film is used, the release layer is transferred to the paper together with the aluminum layer. The OPP transfer film cannot Recycling, the production cost of enterprises is very high. Contents of the invention
