ASTM F 88 covers the measurement of the strength of seals in flexible barrier materials. The test measures the force needed to separate a test strip of the. Seal Strength ASTM F Ultimate Seal Strength of Thermoplastics ASTM F Scope: Seal strength is the tensile strength of the seal at ambient temperature. ISO , Annex B. – Seal Strength. • ASTM F88 – Standard test method for seal strength of flexible barrier materials. • ASTM F – Standard test method.

Historical Version s – view previous versions of standard. Seal strength at some minimum level is a necessary package requirement, and at v88 it is desirable to limit the strength of the seal to facilitate opening. Supported by Hand 90deg; C: Refer to the ASTM specification for conforming test rates.

Manual Vise Grips Pneumatic Grips. We’re happy to help!
Because each technique will produce different results, it is important that the same technique is used for all tests in the same batch and noted in the report. A portion of the force measured to open the seal may as a result of bending forces.
ASTM F88 Package Seal Strength Testing
Each tail of the sealed specimen is secured in the opposing adtm of a universal test bench. Work with us to find the right equipment for your ASTM standard. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Adjust the testing machine to a constant rate of jaw separation.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Work Item s – proposed revisions of this standard. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Pull the sample until separation occurs. ASTM F88 allows for three different sample widths. Thus, three techniques A: Formally confirming that your products and services meet all trusted external and internal standards. Align the specimen in the grips so that the seal line is perpendicular to the f888 of pull.
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Inspection Validating the specifications, value and safety of your raw materials, products and assets. At a certain temperatures a seal force level is reached which is related to the maximum tensile force of the film.

zstm Standards can be obtained from appropriate standard authorities. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
Need help or have a question? 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.
Evaluating how your products and services meet ashm exceed quality, safety, sustainability and performance standards. Properties of interest are the maximum seal force and in some cases the average force to open the seal. 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. When the sample is loaded in the grips, make sure slack remains in the specimen.
ASTM F88 seal strength is not only relevant to opening force and package aetm but to measuring the processes ability to produce consistent seals. The maximum tensile force required to separate the two ends of the seal is recorded. Seal strength is a necessary asstm requirement and oftentimes it is desirable to limit the strength to facilitate opening the package. Sales Support Calibration Calculators.
Send us a request Need help or have a question? Report the algorithm used to calculate the average If failure is by peeling only, calculate energy to separation. Link to Active This link will always route to the current Active version of the standard. 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.
What is Third Party Certification and Accreditation for the food industry? Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals. A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force.
