Plastic sheets are thin, flexible materials made from various types of plastic, such as polyethylene or polyvinyl chloride (PVC). They come in different sizes, colors, and thicknesses, making them suitable for a wide range of applications, including packaging, construction, and crafts. These sheets are often waterproof and resistant to chemicals, which makes them ideal for protecting surfaces or creating barriers. They can be easily cut, shaped, and joined, allowing for versatile use in both industrial and household projects.
