A kind of three-dimensional coating in-mold labeling and in-mold labeling method

Abstract

The invention provides a three-dimensional covering in-mold labeling and an in-mold labeling method. The present invention includes a base film layer, an adhesive layer, and a decorative film layer. The adhesive layer is located between the base film layer and the decorative film layer. It is characterized in that: the decorative film layer includes a printed image ink layer, a decorative film layer The transparent base layer, the textured touch layer, the printed image ink layer, the transparent base layer of the decorative film, and the textured touch layer are sequentially arranged on the side of the adhesive layer away from the base film layer. Realize the three-dimensional coating of plastic containers or component surfaces by in-mold labeling or labels, breaking through the technical bottleneck of traditional in-mold labeling or labels that can only be two-dimensionally coated; by integrating multiple decoration technologies, various fine textures can be generated And the corresponding touch, such as imitation carbon fiber texture, brushed texture and various 3D stereoscopic images, improve product grades; use injection molds and integrated devices to realize one-stop labeling or in-mold three-dimensional coating of labels, improve market efficiency, reduce manufacturing cost.

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.

[0004] With the continuous improvement of product designers and users' requirements for appearance and experience, the two-dimensional plane surface with only pattern decoration has become monotonous, and it is difficult to bring added value to the product in the highly competitive market.
