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 and biomedical research, as well as spinal fluid, amniotic fluid, seasonings, flavors, food supplements, vitamins, marine life, and many other liquid or solid products.
