Widetone Seamless Background Paper from Savage. To facilitate even lighting, the surface of the paper is non-reflective and has a fine-tooth finish. In addition to photography, the paper may be used for events, decorations, banners, and more.
The paper density is 100 pounds, or 145 gsm, an easy-to-handle resilient thickness of 7.6 mil, and comes wound on a core with a 2.125" interior diameter. A plastic sleeve protects the roll in transit and can be saved to provide continued protection when the paper is not in use. The paper should be stored vertically to reduce the possibility of warping and other damage. Photographers often use clamps to secure the paper to a backdrop stand as well as tape to secure the paper to the floor if rolled out for full-body shots. The paper is acid-free and 100% recyclable.
Due to the manufacturing process, it's not uncommon for sizes to fluctuate slightly. In most cases the amount of fluctuation won't matter.
