Light-sensitive substances are often filled into brown glass vials in order to protect them against UV irradiation and light. The disadvantage is that in this case the original color of the preparation is no longer discernible and the medicine cannot be checked for particles or color changes before dispensing it. While transparent glass containers permit the liquids they contain to be inspected, they allow light and UV rays to pass through the glass.
The specialty labels from Schreiner MediPharm for UV and light protection are designed for three safety levels: Level 1 labels have a transparent inspection window with UV protection. At level 2, the labels are equipped with a semi-transparent, colored window and a reclosable inspection window that protects against UV rays and blue light. Level 3 labels consist of an opaque label material for complete light protection; an additionally integrated, reclosable inspection window allows viewing the container content.
All three label concepts are adapted to the specific requirements of the respective substance, the individual containers as well as to UV and light requirements. Manufacturers of biologics and other sensitive products are thus able to effectively protect their highly sensitive substances against light and UV irradiation, avoiding potential health risks for patients due to medicines that have been damaged by light
