When it is necessary to protest 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 colour 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.
- Ideal for pharmaceuticals, seasonings, flavours, food supplements, vitamins, marine life, and many other liquid or solid products
- FDA approved for food contact
