The function of the four-layer structure of thermal transfer film

These four layers Heat transfer film What is its function? Thermal transfer film typically consists of four layers: a base layer, a release layer, a printing layer, and an adhesive layer.

Although a heat-transfer film generally consists of four simple layers, Heat transfer film Multi-layer coating and printing are required. This time, I’d like to share the details with everyone.

Base layer of thermal transfer film: also known as the thermal transfer substrate, it includes polyester film, OPP film, polyvinyl chloride film, and others. The appropriate substrate should be selected based on the material requirements.

Release layer of thermal transfer film: a coating of release agent that remains solid at room temperature, melts at a specific temperature, and blends with the substrate.

Heat transfer film Printing layer: Ink is printed onto the substrate to create an aesthetically pleasing pattern.

Heat-transfer film adhesive layer: A transparent white coating and adhesive are applied over the printed layer, enabling it to adhere to the fabric when ironed.

Heat transfer film After production is completed, thermal transfer products should undergo testing, including tensile strength, brightness, and washability tests. Special materials require additional, tailored tests to ensure product quality. Finished thermal transfer films must exhibit excellent tensile strength, resilience, weather resistance, and washability, while being simple, fast, and convenient to handle.

Different thermal transfer films have different thermal transfer requirements. Pay attention to factors such as transfer temperature, pressure, and speed. When purchasing thermal transfer film, be sure to ask the sales representative about these parameters to prevent transfer failures later on.
