Description

Free coating laser water transfer film

The invention relates to an anti-coating laser water transfer film, which is a water-transfer film with metallic luster and can be transferred onto a curved surface or an irregular surface.

According to the general manufacturing process of water transfer film, most of the polyethylene terephthalate film (PET) with a three-dimensional reflective ink layer technology is coated with a layer of adhesive, and is unrolled in one direction. At the other end, a polyvinyl alcohol film (PVA) is unwound toward the polyethylene terephthalate film, and then the polyethylene terephthalate film and the polyvinyl alcohol film are attached to each other to heat each other. The stereoscopic reflective ink layer on the polyethylene terephthalate film can be transferred onto the polyvinyl alcohol film, but the stereoscopic reflective ink layer of this manufacturing process may not be successfully transferred to the temperature, adhesive or bonding factor. On the polyvinyl alcohol film, the ink layer is broken and damaged. If the finished product is processed, the gold oil must be applied again on the ink layer, which may cause dust to adhere to the gold oil layer. The granules, in the end, result in a decrease in the yield of the finished product, and the polyethylene terephthalate film may be discarded or burned after being transferred, thereby causing the disadvantages of being environmentally friendly and wasting manufacturing costs. A considerable improvement in space.

In view of the above-mentioned shortcomings, the inventor believes that it has the urgent need to make corrections, and that it has been engaged in the design and manufacture of related products for many years, and has always adhered to the excellent design concept, and researched and created the above disadvantages.

Product structure enhances the efficacy of the product.

The main object of the present invention is to improve the manufacturing process of the water transfer film of the prior art. The disadvantage is that the stereoscopic reflective ink layer for this manufacturing process may not be successfully transferred to polyethylene due to temperature, adhesive or bonding factors. On the alcohol film, the ink layer is broken and damaged. If the transfer is successful, the gold oil must be applied to the ink layer again, which may cause dust to adhere to the gold oil layer and cause bumps. However, the yield of the finished product is lowered, and the polyethylene terephthalate film may be discarded or burned after being transferred, thereby causing the disadvantages of being environmentally friendly and wasting manufacturing costs, and the utility is quite large. Improve the space.

For the purpose of the foregoing disclosure, the present invention is an anti-coating laser water transfer film, the main steps of which include a substrate, a coated release layer, a double-layered gold oil, a printing, an implanted message layer, and an embossing. , coated with a metal material, coated with polyvinyl alcohol and a release coil, the substrate is prepared with a rollable continuous polyethylene terephthalate (PET) film, and polyethylene terephthalate The release layer can be coated on one side of the formate film, and the release layer is coated on the side of the polyethylene terephthalate film by a coating device, and the release layer is coated.
