How does pouch lamination work?
Laminating pouches are pockets of laminating film into which the item to be laminated is placed. In most cases a hot laminator is used to seal the pouch and bind the layers together so that your document is laminated. Cold pouch laminators are available, although they are not as common as hot pouch laminators. Two layers: Hot laminating pouches consists of two layers, a polyester-base film layer and an adhesive resin layer that are bonded together. When you run the pouch through your hot laminator, the heat melts the adhesive resin layer, which then spreads over the document, hardening as it cools and creating a bond between the paper and the polyester-based layer of the pouch. Hot lamination material: The polyester and adhesive content in hot laminating pouches is defined as a ratio, sush as 3/2 or 1/4. The first number represents the polyester content, while the second represents the adhesive content. Ratios with larger polyester contents produce stiffer lamination. Ratios with more
