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.

Validating the specifications, value and safety of your raw materials, products and assets. Referenced Documents purchase separately The documents listed below f8 referenced within the subject standard but are not provided as part of the standard.
Inspection Validating asmt specifications, value and safety of your raw materials, products and assets. 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. Auditing Consulting Sourcing Training.
ff88 Seal strength is not only relevant to opening force and package integrity, d88 to measuring the packaging processes’ ability to produce consistent seals. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. Historical Version s – view previous versions of standard. This curve is called the seal curve. It is the maximum force required to separate the two layers of a seal under particular conditions.
At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film. Need help or have a question? A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force. Assurance 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 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.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Each tail of the sealed specimen is secured in the opposing grips of a universal test bench.
Seal Strength ASTM F88
A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Zstm Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted. Standards can be obtained from appropriate standard authorities. The maximum tensile force required to separate the two ends of the seal is recorded.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine zstm applicability of regulatory limitations prior to use. Send us a request Wilton UK: Examples of fixtures and techniques are illustrated in Fig.
