Pouch laminators are the most popular and least expensive method of laminating. They are used to laminate applications as small as identification cards and as large as poster prints and large signs. Pouch laminating machines apply heat and pressure to the laminating pouch fully encapsulating the document. These laminators are generally available in compact tabletop units designed for laminating applications up to 14" wide. Binding101.com also offers a rare wide format pouch laminator for larger applications.
