A paper backed sheet of solid heat activated adhesive, unlike other webs on the market. It has a low temperature/ short pressing time so it allows for a wider range of materials that can be bonded. There is no steam or pressing cloth needed and no lifting or pucker after washing. The Ultrabond is a very strong adhesive and is designed to be used on its own and not need securing by sewing down after fusing. One pack contains a piece 17″ wide by 36″ long.
