Poly Bags
Water Tight
Leak-resistant poly bags built to contain liquids and keep contents dry under pressure.
What are water tight seal bags?
Water tight seal bags are built to stay strong and leak-resistant, even under pressure — where a standard bag would fail when exposed to moisture, these don’t. They are among the most durable bags Rutan manufactures, capable of containing liquids and keeping sensitive materials dry.
Designed to protect contents from spills, rain, and environmental moisture, they are a reliable option wherever packaging integrity is critical and product loss from leakage is unacceptable.
