Weatherproof paper is a type of paper designed to resist moisture, making it ideal for outdoor use. It is often made from synthetic materials or treated with special coatings that prevent water damage, tearing, and fading. This durability allows it to withstand various weather conditions, including rain and humidity. Commonly used for maps, outdoor signage, and labels, weatherproof paper ensures that important information remains legible and intact even in harsh environments. Its applications extend to camping gear, field notes, and any situation where traditional paper would deteriorate quickly due to exposure to the elements.
