SJ INNOTECH has been researching 100% silicone HTF since 2019. Regular vinyl film has problems such as poor film adhesion and a film surface that is easily contaminated, so we started R&D to improve these shortcomings. After years, thousands of tests, and numerous research grants, we finally found a solution! SI SKIN is an environmentally friendly heat transfer film made of silicone, which has great features of durability, lightfastness, easy cleaning and resistance to color migration. It can be heat transferred to a variety of fabrics. It is ideal for sportswear, casual and industrial apparel, including water sports, to print logos, numbers, lettering, etc.
