Abstract

The invention discloses a method for preparing a TPU optical grating composite film with a 2D anti-counterfeiting pattern. The method comprises the steps of PP / TPU optical grating film preparing, optical grating pattern design, optical grating film covering imaging and application process operation. The prepared optical grating film keeps the excellent wear resisting, aging resisting, waterproof and moisture permeable and other properties of TPU, the film can be applied to fabrics of shoe materials, clothes and the like directly through a seamless hot pressing process, knitting is not needed,and a finished product is simple and attractive. Meanwhile, the dynamic pattern improves the decoration fashion, and the commodity characteristics and anti-counterfeiting protection functions are added; a reverse optical grating plate roller is used, the PP / TPU optical grating composite film is produced through curtain coating, and through the composite PP paper, optical grating film printing hand-on and seamless hot pressing process application needs are met.

Description

technical field [0001] The invention relates to a preparation method of a TPU grating composite film with a 2D anti-counterfeiting pattern, belonging to the technical field of TPU film printing. Background technique [0002] Lenticular soft glue not only has good dynamic stereoscopic effect, improves the creativity of commodity images, but also has certain anti-counterfeiting functions, which increases the multiple added value of packaging products, and has a wide range of applications. In recent years, the domestic grating film market has been greatly developed. A group of well-known three-dimensional printing companies, such as Shenzhen Chaoying Image Technology Co., Ltd. and Guangzhou Liankai 3D Image Design Co., Ltd., have developed the application of grating soft rubber, from the handbag and packaging industries to luggage, shoes and hats, and clothing. industry. [0003] In three-dimensional printing technology, the application of lenticular soft glue is considered t...
