When it is necessary to protect a sample from light, the Whirl-Pak® black bag is specially designed for this application. The polyethylene film is made from pigmented resins so the black color is an integral part of the bag and not a printed layer. The result is an opaque bag providing maximum protection for samples that are sensitive to light. It is ideal for pharmaceuticals, seasonings, flavors, food supplements, vitamins, marine life, and many other liquid or solid products. It is FDA approved for food contact.

Shelf life from sterilisation date found on the sterility documentation: 5 years from sterilised date found on your sterility confirmation.
