Dahle's A3-sized laminating pouch, 125 microns thick, sold in boxes of 100 units, is a transparent pouch used to protect documents, cards, and other papers through hot lamination, providing greater durability, water resistance, and protection against repeated handling. The 125-micron thickness is suitable for documents requiring more robust protection and a rigid finish, such as certificates, covers, and identification cards. The A3 size is compatible with most professional and home laminators on the market. It is an essential consumable for offices, schools, and reprographics shops that laminate documents regularly.
