Abstract

The invention discloses a heat transfer film for a soft infusion bag and a preparation method thereof. The heat transfer film for the soft infusion bag orderly comprises a tape base, a release layer and an ink layer, wherein the release layer is prepared from raw materials in percentage by mass: 5 to 30 percent of binder, and 70 to 95 percent of wax; and the ink layer is prepared from raw materials in percentage by mass: 5 to 50 percent of binder, 10 to 50 percent of pigment, 0 to 50 percent of filler, and 0 to 5 percent of additive. The application of the heat transfer film for the soft infusion bag has the characteristics of quick transfer, no adhesion of the tape base, clear print, firm attachment, cooking sterilization resistance, alcohol resistance, no toxicity, no harm and the like,and can meet the need of the printing of surface marks of medical PVC film bags and non-PVC co-extruded films.

Description

technical field [0001] The invention relates to a hot stamping printing material for a transfusion soft bag. It is suitable for printing on the surface of PVC film bags for medicine and non-PVC co-extruded films, and it can also be used for hot stamping on the surface of similar materials. Background technique [0002] At present, the large-scale infusion packaging is rapidly developing from the first-generation glass bottle and the second-generation plastic bottle to the third-generation PVC and non-PVC packaging. The heat transfer film for infusion soft bags is the key component of the third-generation large-scale infusion packaging. part one. Under the action of heat and pressure, it transfers the lettering and other patterns of the hot stamping letterpress to the medical infusion bag and other printing materials through the heat transfer film of the infusion soft bag, forming a clear imprint, firm adhesion, retort sterilization, Non-toxic and harmless packaging logo. ...
