The sample is then put into a tensile testing machine designed to apply a controlled force to the edge of the peelable lid in a pulling motion. This process simulates the peeling action, or steady-state peel force, a consumer would use to open the package. Our technicians document the force required to initiate the peel, or peak peel force, as well as the force needed to continue peeling the lid from the container. These measurements show the exact amount of force required to properly operate the lid and remove the seal. ASTM 2824 testing then analyzes the potential for seal failure caused by unintentional forces, including adhesive failure, cohesive failure, and substrate failure. Various forces are applied to the sample to replicate the conditions commonly experienced in transit as well. ATS’ experts use the yielded data to show clients any potential weaknesses in their packaging design or materials, allowing for product redesign and improvements.
