Semi-transparent IML thin film with textures and processing technology of semi-transparent IML thin film

Abstract

The semi-transparent IML thin film with the textures is provided with a transparent PET thin film and a semi-transparent PET thin film, one side of the transparent PET thin film is provided with a UV transfer printing texture layer, the other side of the transparent PET thin film is provided with a first easy-to-bond layer, one side of the semi-transparent PET thin film is provided with a second easy-to-bond layer, and the first easy-to-bond layer and the second easy-to-bond layer are compounded together through a UV composite glue layer. Compared with the prior art, the semi-transparent effect of the IML film is achieved through the non-full-light-transmitting effect of the colored PET film, no particulate matter exists in manufacturing of the colored PET film, printing is not needed, and therefore no particulate matter is presented when the whole IML film achieves the dual effects of semi-transparent and texture, and the optical display effect is extremely high; the optical display requirements of high use occasions can be met, the light transmittance of the whole IML film can be adjusted, and the application is flexible. The invention further discloses a production process of the semi-transparent IML thin film with the textures.

Description

technical field [0001] The invention relates to a film for in-mold injection molding, in particular to a semi-permeable textured IML film and its processing technology. Background technique [0002] Now on the market there are electrical panels made of IML injection molding. The Chinese name of IML is Injection Molding. Its advantage is that the plastic parts produced are beautiful in appearance and can have various colors and patterns. Compared with spraying process The outer shell is wear-resistant, high brightness, strong three-dimensional effect, and can transfer more complex patterns. Their process is generally to put the printed patterned diaphragm into the metal mold, inject the forming resin into the metal mold and join the diaphragm, so that the printed patterned diaphragm and the resin are integrated and then cured into a product. The notable feature of its process is: the surface is a hardened transparent film, the middle is a printing pattern layer, and the back...
