I just picked up a brand new 56" Big Squeegee laminator with the new "satin" edge. The "satin" appears to be medical/surgical tape. Underneath it appears to be something like double sided foam tape with the liner still attached to one side. This seams to give the edge a little cushion. Is the surgical tape supposed to be the satin material or is this on the squeegee just to protect the edge for shipping purposes?
