At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film.
ASTM F88 / F88M – 15 Standard Test Method for Seal Strength of Flexible Barrier Materials
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Formally confirming that your products and services meet all trusted external and internal standards. Send us a request Need help or have a question?
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. It also identifies the mode of specimen failure. awtm
A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force.

Seal Strength ASTM F88
It is the maximum force required to asgm the two layers of a seal under particular conditions. Each tail of the sealed specimen is secured in the opposing grips of a universal test bench. Send us a request Wilton Aztm Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.

ASTM-F88 – Medical Package Testing
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. The maximum tensile force required to separate the two ends of the seal is recorded. Examples of fixtures and techniques are illustrated in Fig. Work Item s – proposed revisions of this standard.

Validating the specifications, value and safety of your raw materials, products and assets. 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.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability ff88 for virtually any market around the world.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1.
Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. Historical Version s – view previous versions of standard. This curve is called the seal curve. Link to Active This link will always route to the current Active version of the standard. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Combining values from the two systems may result in non-conformance with the standard.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. Standards can be obtained from appropriate standard authorities.
