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.

Formally confirming that your products and services meet all trusted external and internal standards. Need help or have a question? Link to Active This link will always route to the current Active version of the standard. Because the effect of each v88 these on test results is varied, astk use of one technique Technique A, Technique B, or Technique C throughout a test series is recommended.
It is the maximum force required to separate the two layers of a seal under particular conditions.
Combining values from the c88 systems may result in non-conformance with the standard. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Examples of fixtures and techniques are illustrated in Fig.
The maximum tensile force required to separate the two ends of the seal is recorded. This curve is called the seal curve. It also identifies the mode of specimen failure. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to satm consistent seals. Work Item s – proposed revisions of this standard.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force.
Standards can xstm obtained from appropriate standard authorities.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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. Seal strength is the tensile strength of the seal at ambient temperature.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Each tail of the sealed specimen is secured in the opposing grips of a universal test bench.
Seal Strength ASTM F88
At a certain temperatures a seal astk level is reached which is related to the maximum tensile force of the film. 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.
Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted. Inspection Validating the specifications, value and safety of your raw materials, products and assets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Auditing Consulting Sourcing Training. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. Validating the specifications, value and safety of your raw materials, products and assets. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. 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.
