A perfect pairing with our pre-punched paper and hot knife velo binding machines, these pre-punched clear gloss covers create a protective and presentable front page for your documents. They are made of either a lightweight 5 mil or a heavyweight 10 mil. These clear binding covers, sometimes called clear acetate covers, have a high gloss finish that enhances the colors and contrast of your first page. Using velo punched covers means you don't have to spend time punching your sheets. Instead, just place them onto your punched pages and bind, eliminating that step and speeding up the binding process. Velo plastic cover stock sheets are letter size 8 ½" x 11" with square corners, and they are made of an ecid-free plastic material that resists moisture and can easily be wiped clean. They are packaged with 100 per pack, and they are available with either 11 holes punched along the 11" edge or 9 holes punched along the short 8 ½" edge.
