Purple Cows Laminating Pouches, designed for use with the Purple Cows Laminators, are premium laminating pouches that provide a crystal clear protection. Also known as Hot and Kool Pockets, Purple Cows lamination pouches provide an easy solution to the laminating process. The Kool Pockets feature a strong, adhesive back that allows the material to be laminated without the use of heat. Using the Kool laminating pouches ensures a layer of heavy-duty protection and hassle-free application with no need to wait for a machine. The Hot Pockets (not to be confused with the delicious microwavable treats) offer a variety of laminating sizes including 2 x 3", 2 x 4", 3 x 5", 4 x 6", 5 x 7", 6 x 6", 8 x 8", 8.5 x 11", 11 x 17", and 12 x 12". In effect, Purple Cows has created a one-stop solution for all your laminating needs. For the best results, we recommend lamination with a Pouch Carrier. This will prevent any pouches from wrapping around the rollers or jamming the laminator with adhesive.
