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 is the maximum force required to separate the two layers of a seal under particular conditions.
Seal Strength ASTM F88
Send us a request Wilton UK: Because the effect of each of these on test results is varied, f888 use of one technique Technique A, Technique B, or Technique C throughout a test series is recommended. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Auditing Consulting Sourcing Training.
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 astmm 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. 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. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Combining values from the two systems may result in non-conformance with the standard. Assurance Testing Inspection Certification.
Each tail of the sealed specimen is secured in the opposing grips of a universal test bench. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Validating the specifications, value and safety of your raw materials, products and assets. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. Send us a request Need help or have a question?

Need help or have a question? A number of fixtures and techniques have adtm devised to hold samples at various angles to the pull direction to control this bending force. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals.

Formally confirming that your products and services meet all trusted external and internal standards. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
At a certain temperatures a seal force qstm is reached which is related to the maximum tensile force of the film. This curve is called the seal curve. Examples of fixtures and techniques are illustrated in Fig.
The maximum tensile force required to separate the two ends of the seal is recorded. Work Item s – proposed revisions of this standard.
