Seal strength at some minimum level is a necessary package requirement, and at times it is desirable to limit the strength of the seal to facilitate opening. A portion of the force measured to open the seal may as a result of bending forces. ASTM F88 seal strength is not only relevant to opening force and package integrity but to measuring the processes ability to produce consistent seals.

A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force. Sales Support Calibration Calculators.

Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to awtm consistent seals.

ASTM F88 allows for three different sample widths. Adjust the testing machine to a constant rate of jaw separation.

It is the maximum force required to separate the two layers g88 a seal under particular conditions. Refer to the ASTM specification for conforming test rates. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Use a sample cutter to cut the test specimens to size.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
