Pouch Laminators use a lamination pouch that is usually sealed on one side. The inside of the lamination pouch is coated with a heat-activated film that adheres to the product being laminated as it runs through the laminator. The substrate side of the board contains a heat-activated adhesive that bonds the print to the substrate. This can be any of a number of board products or another sheet of laminate. The pouch containing the print, laminate and substrate is passed through a set of heated rollers under pressure, insuring that all adhesive layers bond to one another.
Pouch laminators are designed for moderate use in the office or home. These inexpensive machines are quite effective. However, for continuous, large-volume lamination projects, a roll laminator performs more efficiently.
