ASTM F88 / F88M – 09 Standard Test Method for Seal Strength of Flexible Barrier Materials

Sales Support Calibration Calculators. At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film. Work Item s – proposed revisions of this standard. Seal strength is not only relevant to opening force and package integrity, but to aastm the packaging processes’ ability to produce consistent seals.

Seal strength is a necessary package requirement and oftentimes it is asfm to limit the strength to facilitate opening the package. ASTM F88 seal strength is not only relevant to opening force and package integrity but to measuring the processes ability to produce consistent seals.

Because each technique will produce different results, it is important that the same technique is used for all tests in the same batch and noted in the report. A number of fixtures and techniques have been devised to hold samples at various angles to qstm pull direction to control this bending force. It is the maximum force required to separate the two layers of a seal under particular conditions. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are c88 provided as part of the standard.

Thus, three techniques A: Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.

Examples of fixtures and techniques are illustrated in Fig. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. Report the algorithm used to calculate the average If failure is by peeling only, calculate energy to separation.

Maximum Force per Unit Width Identify the mode of specimen failure If significant peeling within the seal area occurs, calculate Average Seal Strength.

It also identifies the mode of specimen failure. Supported deg have been devised to hold the samples at various angles to help control the bending forces. Send us a request Need help or have a question?


Because the effect of each of these on test results is varied, consistent use of one technique Technique A, Technique B, or Technique C throughout a test series is recommended.

Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. ASTM F88 allows for three different sample widths.

A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
