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.

It also identifies the mode of specimen failure. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. 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.
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.

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 is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. Combining values from the two systems may result in non-conformance with the standard. The maximum tensile force required to separate the two ends of the seal is recorded. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A number of fixtures and techniques have been devised to d88 samples at various angles to the pull direction to control this bending force.
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
