Waterproof paper is a type of paper designed to resist water and moisture. It is often made from synthetic materials or treated with special coatings that prevent water from soaking in. This makes it ideal for outdoor use, such as maps, field notes, and labels that need to withstand wet conditions. In addition to its water resistance, waterproof paper is durable and can be used in various applications, including crafts, packaging, and printing. It is available in different weights and finishes, allowing users to choose the best option for their specific needs, whether for personal or professional use.
