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 responsibility of asstm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws.
Seal Strength ASTM F88
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Seal strength is the tensile strength of the seal at ambient temperature. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1. Validating the specifications, value and safety of your raw materials, products and assets.
A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. Work Item s – proposed revisions of this standard. Need help or have a question? It is the maximum force required to separate the two layers of a seal under particular conditions.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted. A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
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. Historical Version s – view previous versions of standard.
