Manufacturing method of thermoplastic transfer printing bag

Abstract

The invention discloses a thermoplastic transfer printing bag, a manufacturing method thereof and a heat transfer printing method using the thermoplastic transfer printing bag. The thermoplastic transfer printing bag comprises a bag main body and a plurality of transfer printing lines distributed on the surface of the bag main body, wherein the bag main body is internally provided with a hollow covering space, at least one end of the hollow covering space is provided with a penetrating opening for communicating the covering space to the outside; the invention further provides a more comprehensive and convenient transfer printing method based on the thermoplastic transfer printing bag. The thermoplastic transfer printing bag provided by the invention can cover the surface of a workpiece totally to complete heat transfer printing in a wider range, thereby increasing the heat transfer printing efficiency and increasing the aesthetic feeling of the lines subjected to transfer printing, in addition, steps required by the transfer printing can be simultaneously reduced by utilizing the thermoplastic transfer printing bag provided by the invention, which is favorable for considerable transfer printing operation, saves operating time and increasing transfer printing yield.

Description

technical field [0001] The invention relates to the field of thermal transfer printing, and more specifically relates to a thermoplastic transfer printing bag, a manufacturing method thereof and a thermal transfer printing method using the thermal plastic transfer printing bag. Background technique [0002] At present, the existing general heat transfer method is mainly to apply glue on the surface of the workpiece to be transferred, and then manually paste the transfer paper or film on it, and then heat and bake, so that The texture on the transfer paper is transferred to the surface of the coated workpiece. [0003] However, this kind of operation of manually pasting the transfer paper is quite time-consuming and labor-intensive. Moreover, due to the manual pasting of the transfer paper, the adhesion between the transfer paper and the surface of the workpiece is not good, and often occurs Problems with defective products or unclear transfers occur. [0004] Therefore, th...
