If all laminating pouches were the same, you would simply make your purchase decision based upon price alone. Unfortunately, purchasing bargain laminating pouches can often cost you more due to poor adhesion, excessive waste and the cost to re-print and re-laminate your project. The major differences in laminating pouches are the quality of the EVA resin, polyester, and the quality and consistency of the manufacturing process. Lamination Depot thermal pouches are manufactured using only DuPont Elvax ethylene-vinyl acetate (EVA) copolymer resins which produce maximum clarity and superior adhesion to photos and inkjet prints. In addition, our pouches are produced under strict ISO 9001 quality procedures which document 21 quality inspections that each laminating pouch must pass before it can be sold.
