Working principle of in-mold labeling technology

In-mold labeling technology for blow molding machines places pre-printed labels in the mold cavity before blow molding begins. The label is made of special materials and coated with hot-melt adhesive on the back. When the plastic raw material is heated and injected into the mold, the adhesive melts under high temperature and high pressure, so that the label and the plastic bottle are tightly combined, and the product with the label and the bottle body integrated is obtained after the mold is opened.

Advantages compared to traditional labeling

Improve product appearance quality
In-mold labeling achieves seamless bonding between the label and the bottle body, avoiding the problems of bubbles, wrinkles, and warping that occur in traditional labeling. It can accurately present patterns, texts, and colors.
Improve production efficiency
Traditional labeling requires secondary operations after product molding, while in-mold labeling synchronizes labeling with blow molding, reducing production processes and cycles. Enterprises can increase production and improve economic benefits.
Provide better product protection
The label is integrated with the bottle body and has waterproof, oil-proof, and mildew-proof properties. In harsh environments such as humidity, greasy, and high temperature, the label is not easy to fall off and damage.

Wide range of application areas

In the daily chemical industry, such as shampoo, shower gel, detergent and other product packaging, the waterproof and anti-corrosion performance of in-mold labeling meets the needs; in the food and beverage industry, yogurt, juice, condiments and other packaging; in the medical and health care industry, drug packaging has high requirements for label clarity, stability and anti-counterfeiting, and in-mold labeling can meet and realize all functions.
