There are international tests and standards that measure barrier and protection levels objectively. Key examples: OTR, Oxygen Transmission Rate, measures oxygen permeability. WVTR, Water Vapor Transmission Rate, measures moisture transmission, crucial for shelf life. Migration tests, according to EU 10/2011, check whether substances migrate from packaging into food. Shelf life tests simulate the shelf life of the final product, usually done by the customer with the product. Drop and compression tests, ASTM and ISTA, test physical strength during transport. Many tests follow standards like ISO, ASTM, DIN or EN. We ensure our packaging is tested for technical barrier properties. For product specific testing such as shelf life or drop and compression tests, we advise you to collaborate with your own lab or product developer.
