Three-dimensional coating in-mold label and in-mold labeling method

Abstract

The invention provides a three-dimensional coating in-mold label and an in-mold labeling method. The in-mold label comprises a base film layer, an adhesive layer and a decorative film layer, wherein the adhesive layer is located between the base film layer and the decorative film layer, the decorative film layer comprises a printed image ink layer, a decorative film transparent base layer and a texture touch layer, and the printed image ink layer, the decorative film transparent base layer and the texture touch layer are sequentially arranged on one side, deviating from the base film layer, ofthe adhesive layer. The three-dimensional coating of the surface of the plastic container or component by the in-mold label or label is realized, and the technical bottleneck that the traditional in-mold label or label can only be subjected to two-dimensional coating is broken through; by integrating various decoration technologies, various fine textures and corresponding touch senses such as carbon fiber imitation textures, wiredrawing textures and various 3D images can be generated, and the product grade is improved; and by means of an injection mold and an integrated device, in-mold three-dimensional coating of one-stop labels or labels is achieved, the market efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to in-mold printing labels, in particular to a three-dimensional covering in-mold label and an in-mold labeling method. Background technique [0002] The traditional in-mold label or label is based on polypropylene (PP) film as the base film, and the BOPP film with composite printed images on the surface, generally with a total thickness of no more than 0.15. In the injection molding process, the pre-cut two-dimensional plane Labels or labels are attached to the surface of the mold cavity, and the labels are attached to the surface of the container by using the thermodynamic conditions of the injection molding process. At present, only two-dimensional (2D) planes, one-way arc surfaces, and rotating bodies (2.5D) can be achieved. , Surface cladding of regular polyhedron sides.

Problems solved by technology

[0003] Traditional in-mold labeling images are generally printed using gravure printing or flexo printing. Although the images are fine, they are not good in terms of layering, three-dimensional texture, and tactility.
