Are Big Bags waterproof?

Not all Big Bags are leakproof. Some models are specially designed with a laminated fabric and leakproof seams to limit ingress and product loss. Here, "leakproof" is understood as preventing flows from outside to inside. A bulk bag is not leakproof in the sense of being able to contain liquids

Check the product sheet to verify the level of leakproofing for each item.
