preparation example Construction

[0058] see image 3 , the preparation method of the in-mold label film of one embodiment, comprises the steps:

[0059] S110, providing a polymer substrate film.

[0060]By providing the polymer substrate film, it can be used as the substrate for the subsequent preparation of the in-mold label film. It can be understood that the polymer substrate film, as the supporting structure of the in-mold label film, needs to have good physical and mechanical properties and chemical properties, and can meet the In the process of plastic blowing, injection molding or thermoforming to integrate the in-mold label film with the plastic container, it has a certain support function to avoid problems such as curling or wrinkling during the molding process, and at the same time can be integrated with other layers The material is firmly bonded to prevent delamination, and it can have a good fusion effect with the plastic container. For example, the polymer base film is a polyolefin film or a pol...

Embodiment 1

[0091] Provide high-density polyethylene resin base film;

[0092] At a temperature of 150°C, add the first adhesive to the reaction kettle, mix and stir for 30 minutes until it is completely melted, and then coat it on the outer surface of the high-density polyethylene resin substrate film while it is hot. A layer of steel pressure roller laminates the polymer substrate of the silver-plated laser film on the first adhesive, and after the first adhesive is cured, a first adhesive layer is obtained, wherein the first adhesive includes Each component of following mass parts: epoxy resin 10g, polyurethane 6g, methyl methacrylate 4g, hydroxyethyl cellulose 3g;

[0093] 3D true color holographic technology is used to perform laser laser operation on silver-coated polyester film to obtain a laser-laser silver layer. The distance between the laser laser machine head and the silver-coated polyester film is 20cm, the laser energy is 200W, and the laser temperature is 150 ℃, laser time...

Embodiment 2

[0098] Provide high-density polypropylene resin substrate;

[0099] At a temperature of 180°C, add the first adhesive to the reaction kettle, mix and stir for 30 minutes until it is completely melted, and then coat it on the outer surface of the high-density polypropylene resin substrate while it is still hot. Then, use a double layer The steel pressure roller laminates the polymer base layer of the silver-plated laser film on the first adhesive, and after the first adhesive is cured, the first adhesive layer is obtained, wherein the first adhesive includes the following: Each component of mass parts: epoxy resin 12g, polyurethane 7g, methyl methacrylate 5g, sodium dodecylsulfonate 4g;

[0100] 3D true color holographic technology is used to perform laser laser operation on silver-coated polyester film to obtain a laser-laser silver layer. Among them, the distance between the laser laser machine head and the silver-coated polyester film is 25cm, the laser energy is 250W, and t...

Abstract

The invention relates to an intramode label film and a preparation method thereof. The intraomde label film comprises a macromolecular base material film, a silver plating printing film and an ethylene-vinyl acetate copolymer intramode thermoplastic film; the silver plating printing film comprises a first bonding layer, a silver plating laser film, a second bonding layer and a transparent protection layer, the silver plating laser film comprises a macromolecular base layer and a laser silver layer, and the silver plating laser film makes the intramode label film have excellent gloss value; inaddition, information of the transparent protection layer on the intramode label film is complete and is clearly displayed to consumers, and meanwhile the external damage preventing effect is achievedfor the intramode label film. In addition, the invention provides the preparation method of the preparation method.

Description

technical field [0001] The invention relates to a label material, in particular to an in-mold label film and a preparation method thereof. Background technique [0002] In order to make the plastic container achieve the purpose of labeling the contents or decoration, in the traditional craft, manufacturers add patterns or characters on the surface of the plastic container. The usual method is to perform secondary processing on the surface of the plastic container by transfer printing or screen printing after the plastic container is formed. However, the surface pattern or text printed in this way lacks aesthetic feeling, cannot attract the attention of consumers, and even easily falls off, losing the decorative function, and the cost of secondary processing is relatively high. [0003] At present, most of them use paper labels and plastic labels. Due to the simple production process of these two labels, they are widely used on various containers, such as motor oil bottles, ...
