A brief analysis of injection molding in-mold labeling technology

A brief analysis of injection molding in-mold labeling technology. Injection molding labeling technology is widely used. In foreign countries, in-mold labeling technology has been used for a long time. The production and application of in-mold labeling and in-mold labeling machines have been very mature. In-mold labeling is a new form of label packaging that is different from traditional label packaging. Its emergence has brought great innovation to label packaging. In-mold labeling has been popular in many countries for a long time. Currently, products in many countries use in-mold labeling technology.

 In-mold labeling systems are mainly used for blow molded products. In-mold labeling technology uses an in-mold labeling machine to put a trademark (in-mold label) manufactured by a special process into the blow mold cavity while the plastic hollow product is being blown. The blowing of hollow products is completed simultaneously, which simplifies the production process compared with the traditional self-adhesive labeling method, thus greatly improving productivity.

The advantage of in-mold labels is that labels and plastic products are made of the same type of plastic resin, which can be fused into one body at high temperatures in the mold. It combines with nature and has properties such as waterproof, oil-proof, and mildew-proof. It is not easy to fall off in various harsh environments. And the logo is more beautiful. Furthermore, labels and products can be recycled at the same time, which simplifies the regeneration process and takes into account environmental protection. This is consistent with the environmental protection theme currently advocated at home and abroad. And because the in-mold labeling system (including the production of in-mold labels and the application of in-mold labeling machines) is relatively complex, it also reduces the possibility of counterfeiting, which creates challenges for plastic packaging that pursues quality, quality, and brand. Product user manufacturers provide a very reliable means of brand protection. Therefore, hollow packaging products produced using in-mold labeling technology are increasingly popular among users. After waiting and watching in the domestic market for the past one or two years, in-mold labels have finally begun to be applied on a large scale, attracting the attention of more and more industry insiders and users.

 In the past, blow molding machines equipped with imported in-mold labeling systems were 30 to 40% more expensive than ordinary blow molding machines. The price bottleneck has discouraged the majority of users, which to a certain extent has delayed the promotion of in-mold labeling technology. At present, after the hard work of engineering and technical personnel of relevant domestic equipment manufacturers, we finally have a self-developed in-mold labeling machine product. Its price is only about one-half to one-third of that of imported products, and its product performance has reached It surpasses similar imported equipment and has been successfully applied in production, generating economic and social benefits.
