1. Heat transfer film material
There are many types of heat-transfer films, including TPU lettering film, PVC lettering film, and fabric lettering film. Here’s a brief overview of the material used in TPU heat-transfer film: The Q1‑1 series lettering film is made from polyurethane elastomer, features a 100‑micron‑thick high‑temperature‑resistant polyester release liner, and has obtained SGS environmental certification (Level 7) as well as OEKO‑TEX Standard 100 certification.
2. Appearance of the thermal transfer film
Various colors, with vibrant hues; the surface shall meet product specifications (except for special grades and requirements). Special thermal transfer films must comply with their respective specific requirements.
3. Characteristics of Thermal Transfer Film
Heat-transfer films should feature a soft hand feel, excellent stretchability, high opacity, a matte surface, dimensional stability after high-temperature heat transfer, superior weather and water resistance, and ease of engraving, cutting, and waste disposal.
4. Applications of Thermal Transfer Film
Choose the appropriate material based on its characteristics. Heat-transfer film is resistant to stretching, so it’s not recommended for swimwear, as swimwear requires elasticity. Therefore, when selecting heat-transfer film for wholesale, it’s essential to determine the material best suited to your application.
After production is completed, thermal transfer prints 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 apply.
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.
