If you’re in the market for a tarpaulin made from polyethylene, there’s a good chance that you’ve heard about their flexibility, waterproofing and durability. These bad boys are no joke. Especially when compared to other plastic tarpaulins which may be made out of PVC or other materials. Poly tarpaulins reign supreme with better resistance against tearing and UV radiation. High density polyethylene, also referred to HDPE, is another type of tarpaulin that falls under this category, providing a stronger and longer lasting material overall.
