GPI Teflon Heat Sheet works well with any style heat press. Withstands temperatures to 550 degrees Fahrenheit. Can be used over and over again. For best results, wipe it down occasionally to avoid the transfer of residual inks or pretreatments to other surfaces. Be aware that creases in the Teflon fabric can translate to your garment. Having an extra sheet on hand is a good idea. Dimensions are 16" X 20". If you find that inks are sticking to your Teflon Sheet, you may be using too much pressure on your heat press. Clean Teflon sheet with soap and water.
