Patented Whirl-Pak bags, are made of low-density polyethylene plastic (LDPE), which gives the bags superior transparency and extraordinary strength containing liquid, semi-solid, and solid samples.

Features:

• Puncture-Proof Tabs: Eliminate sharp points which could puncture the bags, scratch a person’s hands, or puncture gloves. The “PUNCTURE-PROOF TABS” process is patented under No. 5,180,229.
• Guaranteed Sterile: 1 Sterilization® — process of sterilizing sealed cartons of Whirl-Pak® bags after manufacturing using ethylene oxide gas at an independent ISO-certified facility.
• Film: Exceptionally clear film and superior strength by using co-extrusion low-density and linear low-density, virgin polyethylene.
• Leak-Proof Closure: Whirling or folding the tabs over three times creates a leak-proof sampling container.
• Reduced Storage and Shipping: Whirl-Pak® bags save 90% more space than other sampling containers, which saves on shipping, storage, and waste costs.
