Peel Strength Test
ASTM F88 Standard Test Method for Seal Strength of Flexible Barrier Material This ASTM peel strength test is a common method used to measure the strength of adhesive bonds. This test is worthwhile not only in validating package integrity and seal strength but also in quantifying the amount of opening force required for packaging.
Peel testing is performed by cutting a 1-inch strip on the seal of a sterile packaging system. This test is used throughout the life cycle of a packaging system. First, it establishes a baseline value of your sealing characteristics. Second, as you are completing validations, it serves as a checkpoint of how a seal will perform after sterilization, transit or aging. Finally, the peel test serves as a quantifiable monitoring tool for in-process testing that demonstrates your manufacturing performance over time.
