Our 55mil white sand poly covers are the thickest binding covers that we carry, and they offer the ultimate in rigidity and protection for your documents. In fact, these covers are so thick that they are a popular choice for notebooks as well as various industrial applications. Our sand covers are made from a premium grade 55 gauge white polyethylene plastic. The white covers have a soft matte finish that looks elegant and can be foil printed or silk screened. As you can imagine, these 55 gauge sand poly covers are waterproof, tear-proof, and heat resistant. Since we carry over 500 sand poly covers, you'll want to be sure and select the correct one! Our window covers have a 1.75" x 4" window that is centered on the front cover 3" from the top edge. Please note that these covers are extremely thick. Unless you own a heavy duty modular electric binding punch, we highly recommended that you purchase your 55mil covers pre-punched for the binding style you are using (see list below for available punching patterns). *
