LuminousFlex™
Make a bright statement with a LuminousFlex™!
LuminousFlex™ is a glow-in-the-dark heat transfer vinyl, laminated with a heat sealing adhesive. This HTV is soft and thin, taking on finer details with grace. It feels and acts similar to ThermoFlex® Plus! Our LuminousFlex™ gives your design an unexpected bright green glow when the lights go out.
LuminousFlex™ is suitable for sportswear, leisurewear, and many other applications. Glow-in-the-dark designs are very popular and will make your decoration stand out from the crowd!
There are two types of LuminousFlex™-
- LF-4790 is thicker, has a non-sticky carrier, and no stretch.
- LF-4791 has a blue, sticky carrier and has a little stretch.
Once pressed, both have a gorgeous green glow and a similar look!
