Advantages of in-mold labeling for packaging containers

In-mold labeling has many advantages in bringing aesthetics to packaging and improving economic benefits. Europe developed this technology many years ago and has now entered a mature stage. In recent years, in-mold labeling technology has also been widely used in our country, and has attracted more and more people in the packaging industry to pay attention. The advantages of in-mold labels are mainly reflected in the following aspects:

In-mold labeling

From the perspective of the production process, since the container and labeling are completed at one time, there is no need for subsequent processing, which allows the manufacturer to deliver goods in time, reduce inventory, and improve production efficiency; from the perspective of the materials used, including label materials and container materials . In-mold labeling uses labels that do not require liner material, thus reducing costs. As for the container material, since the label is embedded in the container body, the strength of the container can be improved, thereby reducing the amount of material used in the container. This is a very important aspect today as the cost of materials is increasing.

 Aesthetics. In-mold labels are firmly inlaid, waterproof and moisture-proof, and smooth to the touch. They not only have the overall effect of direct screen printing, but also can perfectly reflect delicate patterns and small text like self-adhesive labels. Since the in-mold label is closely integrated with the body of the packaging container, it can resist collisions, scratches and contamination during production and transportation, unlike self-adhesive and heat shrink labels that are as easy to break and fall off. At the same time, the label can also deform as the packaging container deforms, without bubbles or wrinkles.

Environmental friendly. Although there are many materials for in-mold labeling, common plastic containers are matched with materials of the same composition. Since the label is integrated with the container body, it is easy to recycle the container. Anti-counterfeiting. Enhancing the anti-counterfeiting capabilities of products is one of the important starting points for manufacturers who pursue product quality and brand to choose in-mold labeling. The high technical content of in-mold labeling increases the difficulty of counterfeiting. Its high technology is mainly reflected in material selection, label production, mold structure design, production equipment and technology, etc., requiring all links to be interlocked and closely coordinated.

In-mold labeling is to first print, wear-proof, and die-cut the synthetic film into a special and exquisite label, and then use a robot to send it to the inside of the mold. During the molding process of the plastic product, the waste heat of the plastic is used to melt the special bottom layer of the label. , thus integrating the label with the plastic product. When the mold is opened, a beautifully printed injection molded part is completed in one go.

In-mold labeling is a new form of label packaging that is different from traditional direct screen printing, heat shrink labels, and self-adhesive labels. After 3 to 4 years of lingering in the country, this technology has begun to enter a stage of rapid development on a large scale. , is gradually attracting more and more people’s attention.
