In-mold labeling is a new technology for decorating the surface of plastic products. It is different from the traditional direct silk screen printing, heat shrink label, self-adhesive label and other new label packaging forms. It is mainly used for blow molding and injection molding products of materials such as PP, PE, and PET.
Before blow molding and injection molding, put the printed in-mold label into the blow and injection mold cavity. When the mold is closed for blowing and injection, the special adhesive on the in-mold label is melted by the high temperature and high pressure in the mold, and it is integrated with the surface of the bottle or injection molded part. When the mold is opened, a beautifully printed bottle or injection part is completed at one time.
With the continuous development of in-mold labeling technology, the market share will become larger and larger. What are the advantages of in-mold labeling?
In-mold labeling can well deal with the problem of self-adhesive labels warping and falling off on some product packaging. Compared with self-adhesive labels, its anti-counterfeiting function is more advantageous.
The in-mold label is naturally integrated with the plastic bottle body, and the inlay is firm. The label changes with the shape of the bottle body. The corners of the label cannot be seen on the plastic bottle body, and the appearance looks very beautiful. There will be no bubbling, wrinkling and other phenomena. It can resist the bumps, scratches and pollution during production and transportation, so that the label can remain intact and beautiful for a long time. In a humid environment, the in-mold label will not bulge or mold. It feels smooth, especially for daily chemical products with labels as the primary outer packaging. The benefits are self-evident.
At the same time, the in-mold label can print detailed and delicate design pictures, with strong visual expression, which can reflect the exquisite pictures and small texts of the self-adhesive label, and has the overall effect of direct silk screen printing.
In addition, if a transparent in-mold label is used, the transparent material can better express the clean and safe characteristics of the product. In addition to being able to clearly convey the effect of no label, combined with a transparent packaging container, it can allow consumers to see the actual contents, which will attract consumers more.
The double-layer composite in-mold label material can not only effectively deal with the problem of static electricity, but also "seal" the printing ink between the two layers of film, which can eliminate the possibility of human contact with the ink. In addition, the double-layer composite not only increases the effect of brightness, but also the printing effect is not damaged even if there is friction during transportation. It has the functions of waterproof, oil-proof, acid and alkali resistant, friction-resistant, freezeable, and soakable. It has excellent chemical stability, which can not only keep the label intact and beautiful for a long time, but also is more beneficial to the environment.
The in-mold labeling and container molding are completed at one time, eliminating the process of manual labeling secondary processing. Labels can be added and replaced without stopping production, making packaging production faster and product efficiency higher.
