Laminating pouch's main material is PET film, we coat PE,EVA on PET film. to make best quality laminating film, we insist on using best material. import PE from Japan, and import EVA from Korea. our film can be cutted from A2 to any smaller size. After laminating, the paper/photo looks shiny, it is anti scratch, waterproof, and dustproof. Because there is PE in the film, the film has very strong bonding adhesive, never seperate automatically. the paper/photo can be protected for very long time. it is the best choice to protect your valued file and photo.
