With the improvement of people's living standards and the acceleration of modern life and work rhythms, casual foods have become an essential part of daily life. From biscuits and chocolates to dried fruits, canned goods, and chewing gum, these snacks are everywhere. Some snack items like cookies and chocolates even serve as staple food in certain situations.
Due to their portability, casual foods often come in colorful and attractive packaging. In many of these products, you can find in-mold labeling. With the development of in-mold labeling technology, a new wave of innovation is transforming the packaging of snack foods.
**Biscuit Boxes Use In-Mold Labeling - Retaining the Color Richness of Soft Plastic Packages and Increasing the Strength of Packaging**
As we know, biscuit packaging has traditionally been done with plastic bags or metal boxes. However, soft plastic packaging lacks strength and can easily break during transportation. Metal boxes, while more durable, are heavier and increase transportation costs. In-mold labeling offers a better alternative by enhancing the strength of the packaging while reducing its weight. This not only lowers transportation costs but also improves the sealing performance of the package.
A well-known company, Guangzhou Kwai Food Co., Ltd., was among the first to apply in-mold labeling to hard plastic biscuit boxes. Compared to traditional soft plastic packaging, this method significantly increases the strength of the packaging. Compared to tin packaging, it reduces the weight and lowers transportation costs, while improving the seal. The use of fully enclosed injection molded in-mold labeling ensures the product's appearance. Because of this innovation, the product won the first China In-Mold Labeling Technology and Application Award.
**Chocolate Uses In-Mold Labeling - Enhances the Appearance of the Product and Ensures Product Safety**
Mars Foods (China) Co., Ltd. was the first to apply in-mold labeling to 100g M&Ms in its chocolate products. Compared to previous screen printing and bottle cap printing methods, in-mold labeling not only enhances the product's appearance but also ensures food safety. Due to the multi-surface nature of the packaging (R > 110), traditional labeling methods struggle to achieve good results. In-mold labeling, however, can perfectly label micro-curved surfaces with high accuracy. This innovation earned the product the second China In-Mold Labeling Technology and Application Award.
**The Packaging of Dried Fruit and Meat Products Adopt PET In-Mold Labeling, Which Greatly Facilitates Production and Improves Aesthetics**
Dried fruit and meat products are typically packaged in PET open cans and then labeled with regular labels. However, due to the thinness and low strength of the packaging containers, various issues may arise during the labeling process. In-mold labeling provides an effective solution to these problems, especially as PET containers become thinner. This method avoids labeling difficulties during the blowing process and allows the container to return to its original shape after being squeezed or deformed. The label also remains intact without falling off. It is expected that in-mold labeling will become a mainstream packaging method for PET bottles in the future.
**Application of In-Mold Labeling for Chewing Gum Products - A New Choice for Packaging**
At the recent CHINAPLAS 2015 exhibition, Jiangsu Weida Machinery Co., Ltd. and Guangzhou Xinbiao Electromechanical Technology Co., Ltd. combined PP/PE injection blow-molding equipment with in-mold labeling robots to realize in-mold labeling of PP/PE containers. At the exhibition, a container similar to a chewing gum product was displayed. These containers have an attractive appearance, good sealing performance, and effectively solve labeling problems. Additionally, the labeling speed is relatively fast, enabling high-speed production and avoiding labeling issues.
In summary, in-mold labeling, as one of the major packaging methods, is gaining increasing recognition from users. As supporting facilities continue to improve, it will leverage its advantages to provide practical packaging solutions for product packaging.
