Protect your important papers with this 600-pack of thermal laminating pouches. Each pouch is designed to fit regular-sized printing paper (letter size), which is 8.5 x 11 inches. The pouch itself is slightly larger at 9 x 11.5 inches, giving enough space to fully seal and protect the edges. Made from strong, clear material, these pouches are waterproof, tear-resistant, and ideal for documents, certificates, photos, and artwork. Works with any brand of thermal laminating machine — great for home, school, or office use.
