Description

When it is necessary to protect a sample from light, the Whirl-Pak® Black Bag is specially designed for this application. Ideal for pharmaceuticals, seasonings, flavors, food supplements, vitamins, marine life, and many other liquid or solid products.

• ​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.
• A convenient white Write-On Strip will accept virtually any writing instruments (ballpoint pen, pencil, or felt-tip marker) for easy sample identification
• High-quality blended polyethylene bag for maximum strength
• Puncture proof tabs by extending the tape on the tab past the aluminum wire ends eliminating the sharp points which could puncture the bags or gloves
• Leakproof closure (whirling or tightly folding the tab over 3 times) prevents impurities from entering the bag and contaminating the sample
• Sterile with +1 Sterilization, a process of sterilizing sealed cartons of Whirl-Pak® bags after manufacturing using ethylene oxide gas at an independent ISO-certified facility
• Not autoclavable
• Bags should not be used at temperatures above 180°F (82°C)
• Bags can be frozen to any temperature, even liquid nitrogen temperatures down to -346°F (-210°C); careful handling required after freezing
• ISO9001 certified
• FDA approved for food contact
