Are HDPE cases waterproof?

HDPE (High-Density Polyethylene) cases can be waterproof, but it depends on the specific design and construction of the case. HDPE is a durable and rugged material that is commonly used to make hard-sided cases for transporting sensitive equipment and gear. However, not all HDPE cases are waterproof.

If you need a waterproof HDPE case, look for cases that are specifically designed to be waterproof. These cases usually have features like rubber gaskets, watertight seals, and pressure relief valves to keep water and moisture out. Some manufacturers also include an IP (Ingress Protection) rating on their cases to indicate the level of protection against water and dust.

It's important to note that even if a case is advertised as "waterproof," it may not be completely impervious to water. Factors like the duration and depth of exposure to water, as well as the specific design of the case, can affect its waterproof capabilities. It's always a good idea to test a case's waterproofness before trusting it with valuable equipment or gear.
