Whirl-Pak® Light Sensitive Bags

The Whirl-Pak® black bag is specially designed to keep light-sensitive materials safe. The polyethylene film is made from pigmented resins, so the black color is an integrated part of the bag and not just a printed layer. The result is an opaque bag providing maximum protection for samples that are sensitive to light. It is ideal for pharmaceuticals, forensics, genetics, biomedical research, spinal fluid, amniotic fluid, seasonings, flavors, food supplements, vitamins, marine life, and many other liquids or solid products.
