Container seals guarantee a certain quality of the product inside. Weather the container is a foil bag holding delicious potato chips or a sterile medical device critical to a surgery, the seal on the container must hold strong to preserve the integrity of the item inside. With respects to quality control efforts, barrier properties such as seal strength, and peel strength are indicators of how well a container is sealed, which is a revelation to the leak prevention and shelf life properties of that packaging. The specific manner in which the peel test is done to determine the sealant properties of your product package is dependent of standards that must be met. These standards might be internally based, industry based, or requirement based. ASTM F88 is a commonly followed test method for determining the seal strength of packaging materials. ASTM F88 describes a 90 degree, 180 degree, and T peel testing for flexible barrier materials. This standard test practice is used to determine maximum or average seal strength. If you are looking for more information on 90 degree or 180 degree peel test, then ASTM D903 would be a good fit. Finally, if you are looking for more information on T peel test, see ASTM D1876. TestResources universal material testing machines are effectively used for determining the peel strength, bonding strength, and sheer properties of adhesives. TestResources test machines meet the requirements specified in many standard test procedures for constant-rate-of-extension and constant-rate-of-load machines. This allows the machines to be programmed to perform many unique testing procedures. Load cells are fitted to specific load applications to ensure the highest resolution of tests.
