ISO , Annex B. – Seal Strength. • ASTM F88 – Standard test method for seal strength of flexible barrier materials. • ASTM F – Standard test method. Seal Strength ASTM F Ultimate Seal Strength of Thermoplastics ASTM F Scope: Seal strength is the tensile strength of the seal at ambient temperature. ASTM F88 is the standard followed when performing Peel tests on Packaging. Peel Tests determine ‘Seal strength’ of the package, which is defined as the.

A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force.
ASTM F88 / F88M – 09 Standard Test Method for Seal Strength of Flexible Barrier Materials
It also identifies the mode of specimen failure. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film. Send us a request Need t88 or awtm a question? The maximum tensile force required to separate the two ends of the seal is recorded. Combining values from the two systems may result in non-conformance with the standard.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.
Seal Strength ASTM F88
Examples of fixtures and techniques are illustrated in Fig. A rectangular specimen is used; the specimen width may be either 25 f888, 15 mm or 1. Seal strength is the tensile strength of the seal at ambient temperature.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Each tail of the sealed specimen is secured in the ff88 grips of a universal test bench.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. It is the maximum force required to separate the two layers of a seal under particular conditions. Historical Version s – view previous versions of standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
This curve is called the seal curve. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. Work Item s – proposed revisions of this standard. 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.

A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. Need help or have a f888 Assurance Testing Inspection Certification.

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.
Standards can be obtained from appropriate standard authorities.
Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
