Embodiment Construction

[0034] refer to figure 1 with figure 2 , The invention is a method for making an in-mold label.

[0035] Laser holography technology uses the basic laws of scattering, reflection, transmission, diffraction, interference, absorption, etc. when light is irradiated by matter, and then forms different visual effects. A high-energy laser beam is generated by a laser generator, and the nickel plate is partially irradiated by engraving or vector contour cutting in a dot matrix to make the surface instantly melt or even gasify. At this time, the material on the surface of the nickel plate is chemically And physical changes show traces, and then form the required characters, symbols and patterns according to the pre-design requirements. After the laser beam is focused, the processing accuracy is at the millimeter to micron level, and the heat-affected area in the laser processing process is small, and the final processed surface is of high precision, which is why the laser is used t...

Abstract

The invention discloses a manufacturing method of in-mould labels. The main steps comprises the following steps of: manufacturing holographic laser embossment moulded board, manufacturing laser embossment film, vacuum spraying, positioning and cutting into rolled coil material, positioning and secondary printing, increasing adhesive layer, curing, applying cloth varnish, mould cutting and mouldingand final packaging. At present, the holographic laser anti-counterfeiting label products are limited to paper boxes, soft packaging, and the like, more visual label products are difficult to achievedue to the complexity of the process, and no label product is used in the in-mould label; through the long-term practice, this scheme creatively combines platinum embossment technology and in-mould label technology, changing the situation that there is no holographic anti-counterfeit label in the industry, and solving the current situation that the in-mould label with holographic anti-counterfeiting label in the industry can not be produced. This manufacturing method of in-mould labels is used in the field of high-end cigarette, wine, cosmetics and gift boxes.

Description

technical field [0001] The invention relates to the field of packaging boxes for high-end cigarettes, alcohol, cosmetics and gifts, in particular to a method for making in-mold labels. Background technique [0002] Glossary: [0003] Platinum laser embossing, which is an intuitive anti-counterfeiting technology, adopts laser embossing plate making technology combined with UV molding technology, and the finished products of laser embossing have the advantages of strong three-dimensional sense, good logo brightness, and high precision level. [0004] In-Mold Labeling: In-mold labeling is a one-time simultaneous molding process of the plastic container / part and the attached label, which is fused to the plastic container part for a visual "label-free" appearance. Typically, an in-mold label structure consists of a printing surface, an intermediate layer, and an adhesive layer. The role of the printing surface is to accept ink to form color graphics; the middle layer supports t...
