This silicone foam sheets is used by placing the material over the exposed textile and around the product you wish to heat seal. Any imprint coming from the platen or carrier is transferred to Impressio rather than to the garment.
Impressio is supplied in 4 sheets (16.5″ x 19.68″)
Some pneumatic large platen heat seal presses cannot generate enough pressure to seal as instructed above. For machines such as these it is advisable to put a piece of Impressio underneath the garment on the spot where the heat seal product is planned. Then place the garment on the lower sealing platen as shown in the sketches and heat seal.
Ensure the strips are laid against each other, not on top of each other, for even pressure.
