Hospital bags - often called hamper bags - are easily identified because they have flip top closures instead of draw cords. The JCHC usually requires this type of bag in hospitals to help with infection control.They are used in health care, where germs need to be as contained as possible. Hamper bags were originally made of 100% cotton, then poly/cotton blends. However, almost all hamper bags are made of 100% synthetic material, which does not absorb germs, odors, or moisture.
Many hamper bags are made of fluid resistant barriers, or even 100% fluid retardant fabrics. They are often printed with biohazard logos.
