Calico vs Non Woven bags. Which type are waterproof? The answer is non woven bags. These bags are essentially made from strands of plastic which are woven into a fabric like appearance. Calico bags on the other hand is essentially untreated cotton. Therefore like a shirt it would absorb water.
Non woven Bags are generally splash proof however we definitely do not recomend them to be soaked in water. So if you do have an outdoor conference and you are unsure if it may rain or not please consider non woven bags instead as it may protect your prescious pamphlets and contents for your event!
