Light protection is extremely important in health care, and UVLI-bags are designed to provide protection against the deteriorating effects of ultraviolet light. UVLI-bags are routinely tested for effectiveness as part of the Medipak Quality Assurance and Control Program. UVLI-bags are cost effective – no more than pennies need be spent to protect IVs that often cost $50 and up to administer. Easily accessible in stackable boxes.
