Heat Transfer Film for Plastic Buckets

Heat transfer film is the technology behind millions of decorated plastic containers worldwide — from paint buckets and engine oil drums to cosmetic jars. This guide covers the complete process, applications, and how to choose the right film for your packaging line, based on real production knowledge from ULIKE, a 30-year Chinese manufacturer.

What Is Heat Transfer Film?

Heat transfer film is a PET-based carrier film pre-printed with a design, which is then bonded onto a plastic container surface using heat and pressure. The ink transfers from the film onto the container, leaving a durable, high-resolution pattern. It is the dominant decoration method for PP and PE plastic buckets, bottles, and containers across the chemical, food, and household product industries.

How the Transfer Process Works

✔ Design & printing: Pattern is printed onto the film using specialised inks
✔ Preheating: Film and container surface heated to a set temperature
✔ Transfer: Film is pressed onto the container, transferring the ink
✔ Cooling: Pattern bonds permanently as the surface cools
