Pouch laminators generally use a stiff cardboard envelope called a 'carrier' used to hold a plastic pouch and photo or document to be sealed as it's run through the laminator. Our fiberglass "carrier" allows maximum heat & pressure to be delivered to foils and heavy paper stocks for perfect foil transfers.
These plastic pouches are too thin and flimsy to go though the laminator without some sort of semi-rigid carrier. The problem using this sort of carrier for foiling, is that it is too thick, insulating too much heat from getting to the foil & toner image, resulting in a poor transfers. Because of this, we developed our own carrier system that allows all of the roller heat and pressure to get to the foil and print, resulting in perfect transfers.
In order to get maximum heat delivered to the foil toner image, we use a rigid .020" thick fiberglass board to keep the work piece perpendicular to the pressure rollers. Attached to the board is a very thin sheet of Mylar film only 1/2mil (or .0005") thick, as the 'top cover' to the board, affixed by a strip of paper-type tape from the back of the board. The Mylar allows full roller heat to pass right through to the particular foil you're transferring to the toner printed image.
With our Carrier Board you can see where you've placed the selected foil (or multiple pieces of different color foil) over the print. You then lay the attached Mylar over everything which holds the foil pieces in place. After inserting into the laminator, you merely tug on the tail of the Mylar to prevent any foil from wrinkling as the board passes through the laminator. After many uses the Mylar may need to be replaced for a fresh piece. This kit comes with 10' of Mylar to make changing very easy to do. Also, the letter-size fiberglass board can be easily cut to smaller sizes using any paper-cutter when working with a lot of smaller pieces... faster to pass through the laminator instead of waiting for the entire 11" long board to completely pass through the unit. Many power-users get an extra board and have various sizes to quickly select for the task at hand.
Many times, toner prints have toner particles or 'dust' sitting on top of the toner image. A particle of loose or unfused toner dust can be lifted off from the toner image after the foil has been transferred and subsequently peeled off. If a dust particle is lifted off from the print, this will cause a black spec to show through the foil which looks pretty bad. For this reason we include a "tack rag" in the kit, used to wipe over the toner print, lifting off any such toner dust before the foil is transferred.
