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.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Auditing Consulting Sourcing Training. This curve is called the seal curve. Formally confirming that your products and services meet all trusted external and internal standards.
Seal Strength ASTM F88
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. Seal strength is the tensile strength of the seal at ambient temperature.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently astn the other. 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.
Seal Strength ASTM F88
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
Combining values from the two systems may result in non-conformance with the standard. Validating the specifications, value and safety of your raw materials, products and assets. Examples of fixtures and techniques are illustrated in Fig. 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.

Historical Version s – view previous versions of standard. Need help or have a question? At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film. The maximum tensile force required to separate the two ends of the seal is recorded.

Send us a request Wilton UK: It is the maximum force required to separate the two layers of a seal under particular conditions. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force. Link to Active This link will always route to the current Active version of the standard. Assurance Testing Inspection Certification.
