Transfer printing film capable of printing

Abstract

The invention discloses a printable transfer film which comprises a transfer carrier film (1), a release layer (2) and a thermal welding layer (5). The printable transfer film also comprises a printable layer (6). The transfer carrier film (1) is totally covered with the release layer (2) which is totally covered with the thermal welding layer (5). The thermal welding layer (5) is totally covered with the printable layer (6). A background layer (4) is clipped between the printable layer (6) and the thermal welding layer (5) and is characterized in that the printable layer (6) and the background layer (4) can be integrated into one through changing the resin polarity of the background layer (4) and adding printable auxiliary agent.

Description

technical field [0001] The invention relates to a printable transfer film. Background technique [0002] The transfer printing of textiles and leather is to print the graphics and texts on the textiles or leather by hot pressing the pre-printed transfer film with graphics and hot-melt adhesive layer. This transfer film is composed of a transfer carrier film, a release layer, a color layer and a hot-melt adhesive layer. The transfer carrier film can be PET, OPP or paper, and the color layer can be screen printing, offset printing or gravure printing. To be done. There is generally a background layer between the hot-melt adhesive layer and the color layer. This layer is generally used for silk screen printing, and a small part for leather transfer printing is completed by gravure printing. Because offset printing is very thin, the ink is transparent and has poor covering power, so there must be a background layer; silk screen printing and gravure printing also need white or ...

AI Technical Summary

Problems solved by technology

The above-mentioned production method has many procedures, and it is difficult for workers to control the operation. The most important thing is to make a plate when printing the color layer. Silk screen printing needs to use a silk screen printing plate, gravure printing needs to make a gravure printing plate, offset printing needs to make a PS plate, and it also involves negatives. In this way, it is difficult to bear the small order quantity, and the personalized production cannot be realized, and the technical requirements and equipment requirements for the transfer film manufacturers are high.
