Laminating film is a thin, transparent plastic sheet used to protect and enhance documents, photos, and other printed materials. It is typically made from materials like polyester or polypropylene, which provide durability and resistance to moisture, dirt, and fading. Laminating film comes in various thicknesses and finishes, such as glossy or matte, allowing users to choose the best option for their needs. When a document is laminated, the film is sealed around it using heat or pressure, creating a protective barrier. This process not only preserves the item but also gives it a polished appearance, making it ideal for items like business cards, menus, and educational materials.
