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.

Examples of fixtures and techniques are illustrated in Fig. Send us a request Need help or have a question? 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.
This curve is called the seal curve.
Seal Strength ASTM F88
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film. Seal strength is the tensile strength of the seal at ambient temperature. F888 is the maximum force required to separate the two layers of a aatm under particular conditions. Standards can be obtained from appropriate standard authorities.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It also identifies the mode of specimen failure. Certification Formally confirming that your products and services meet all trusted external and internal standards.
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. 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.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Need help or have a question? A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. A number of fixtures and techniques have been asgm to hold samples at various angles to the pull direction to control this bending force.
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. Link to Active This link will always route to the current Active version of sstm standard. Validating the specifications, value and safety of your raw materials, products and assets.
Combining values from the two systems may result in non-conformance with the standard. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Send us a request Wilton UK: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Work Item s – proposed revisions of this standard. Each tail of the sealed specimen is secured in the opposing grips of a universal test bench.
A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. The maximum tensile force required to separate the two ends of the seal is recorded. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
