Polypropylene Express Sheet Protectors are made of unplasticized, heat resistant and chemically stable archival quality .0045 polypropylene. The sheets pass the PAT test and feature a non-stick and non-reflective finish to prevent adhesion to artwork and minimize glare. They also feature a superior scratch resistance that allows artwork to look better longer.
The sheets have a “weld" that runs parallel to the binding edge and acts as a hinge, allowing the sheets to lie perfectly flat.
They are top-loading and available in packs of 10 in protective metallic resealable bags.
