Specimen Transport Bags

Lab Bags

Lab Bags are made from durable, moisture and leak resistant co-extruded polyethylene. Choose from open-end or open-side constructed bags with a special leak-resistant and tamper-evident, self-seal adhesive closure system and burst resistant side pouch seals. Also known as pharmaceutical bags and specimen bags, these packages are designed as an overwrap or secondary packaging for any shipments that require containment from possible leakage of primary packaging, such as bodily fluids being transported for testing in centralized laboratories.

Environmentally Friendly

Lab Bags are 100% recyclable poly mailers made of #4 LDPE. Eliminate the need for corrugated boxes, air filled pillows, packaging peanuts or crumpled kraft paper and stop over packaging. Not only will you decrease DIM weight costs by downsizing to mailers, but you will decrease your total carbon footprint as well.
