In today's conditions, many products are on the market shelves. Food, cleaning and packaging products are at the top of these products. It is of great importance to determine the strength of these products under different lights that they are exposed to during and after their transportation from their production sites to their place on the market shelves. Determining the resistance of the product depending on the type of light source to which it will be exposed before it takes its place on the shelf is possible with "Shelf Life" and "Photostability" tests.

In TÜBİTAK BUTAL Material-Textile Laboratory, photostability test for the resistance of food, cleaning and packaging products under sunlight during their transportation from the production warehouse to the market at the point of sale and shelf life test for the resistance of these products against the light they are exposed to on the market shelves.
