Acetate sheets are thin, transparent plastic sheets made from a type of polymer called cellulose acetate. They are commonly used in various applications, including art projects, overhead projectors, and packaging. Their clarity and flexibility make them ideal for creating overlays and protective covers. These sheets can be easily printed on or drawn upon, making them popular among artists and educators. Additionally, acetate sheets are resistant to moisture and chemicals, which enhances their durability. They are available in different thicknesses and sizes, catering to a wide range of creative and practical uses.
