This manufacturing process by Zhongyu enables this China PP Paint Bucket Injection Molding IML Label to have excellent wear resistance, scratch resistance, and high-temperature resistance. The patterns remain intact and clear throughout the entire lifecycle of the paint bucket, achieving the integration of packaging decoration and structure.


1. Gravure printing on PET/PP film and Lamination
2. Cutting into standard label sheets
3. Automatic robot places labels into injection mold cavity
4. Plastic melt injection, film and plastic melt into one piece
5. Demold finished IML plastic products directly
The manufacturing process of this PP Paint Bucket Injection Molding IML Label mainly consists of three core stages, providing end-to-end precise services to global customers:
- High-precision printing stage: Using intaglio printing, it supports up to 10 color overprinting, enabling various visual effects such as gradients, logos, metals, and lasers, and a design team is available to provide free design assistance.
- Precise die-cutting and quality inspection stage: The printed rolls are precisely cut to the mold size in a 100,000-grade GMP cleanroom, with full machine inspection to ensure no dust or flaws on the labels.
- Injection fusion stage: The client's mechanical hand automatically inserts the label, and the molten PP is injected into the mold under high temperature, relying on heat pressing to achieve the molecular fusion of the label and the bucket body, completing the product molding in one step.
