The Pina Zangaro Polypropylene EXPRESS Sheet Protector are welded protectors and represent one of the highest standards the industry has to offer. The weld parallel to the binding edge acts as a hinge, allowing the sheets to lie perfectly flat, making these sheets ideal for use in screwpost books. They are great for presentation of art and print work.
Note: These Express protectors differ from regular Pina polypropylene protectors - no liner sheet and are punched only for use in screwpost books and 3-ring binders
