Blind and Protect Light-Sensitive Medications

Medipak offers the widest variety of UV protective and blocking bags available. All UVLI® Covers and Bags exceed United States Pharmacopeia standards for UV light protection. State-of-the-art USP compliant testing equipment ensures the quality you depend on. Our blinding bags are available in black and dark brown, and our protective bags are available in UVLI® amber and UVLI® green. Amber and green bags are semi-transparent allowing labels and levels to be read without lifting the cover.

UVLI® Technical Data

United States Pharmacopeia states that no more than 10% of UV light transmission from 290nm to 450nm is acceptable. Brown and black bags block 98% or more of transmission in that range while UV Amber and UV Green exceed the minimum by allowing the transmission of less than 8% while remaining semi-transparent for ease of use. 

Single-layer film thickness: ~1.6 Mil
Flat cover film thickness: ~3.2 Mil

  • Packaged pre-cut tubing includes 10 strips in 6-foot lengths.
