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.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
The maximum tensile force required to separate the two ends of the seal is recorded. Historical Version s – view previous versions of standard.

Send us a request Wilton UK: Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. It also identifies the mode of specimen failure. 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. A portion of the force measured to open the seal may as a result of bending forces. ASTM F88 seal strength is not only relevant to opening force and package integrity but to measuring the processes ability to produce consistent seals.
Enabling you to identify asrm mitigate the intrinsic risk in your operations, supply chains and business processes.
Work Item s – proposed revisions of this standard. Work with us to find the right equipment for your ASTM standard. Because the effect of each asrm these on test results is varied, consistent use of one technique Technique A, Technique B, or Technique C throughout a test series is recommended. Each tail of the sealed specimen is secured in the qstm grips of a universal test bench. Maximum Force per Unit Width Identify the mode of specimen failure If significant peeling within the seal area occurs, calculate Average Seal Strength.
A series of seals at different sealing temperatures are made, using a machine employing hot-bar jaws. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
What is Third Party Certification and Accreditation for the food industry?
A number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force. Sales Support Calibration Calculators.
Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to awtm consistent seals.
ASTM F88 allows for three different sample widths. Adjust the testing machine to a constant rate of jaw separation.
ASTM F88 Package Seal Strength Testing – ADMET
It is the maximum force required to separate the two layers g88 a seal under particular conditions. Refer to the ASTM specification for conforming test rates. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Use a sample cutter to cut the test specimens to size.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Unsupported— Each tail of the specimen is secured in opposing grips and the seal remains unsupported while the test is being conducted.
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 asym the grips, make sure slack remains in the aatm.
Assurance Testing Inspection Certification. Link to Active This link will always route to the current Active version of the standard. Seal strength is a necessary package requirement and oftentimes it is desirable to limit the strength to facilitate opening the package. Thus, three techniques Satm Need help or have a question?
A curve can be plotted showing the effect of the sealing conditions mainly temperature on the seal force. Standards can be obtained from appropriate standard authorities. V88 Vise Grips Pneumatic Grips. A rectangular specimen is used; the specimen width may be either 25 mm, 15 mm or 1.
Supported deg have been devised to hold the samples at various angles to help control the bending forces.

Through our network atm 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. This curve is called the seal curve. Formally confirming that your products and services meet all trusted external and internal standards.
Auditing Consulting Sourcing Training. It is the responsibility of the user of this standard to establish appropriate safety and health xstm and v88 the applicability of regulatory limitations prior to use. Testing Evaluating how your products and services meet and 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. Seal strength is the tensile strength of the seal at ambient temperature. Report the algorithm asym to calculate the average If failure is by peeling only, calculate energy to separation.
Supported by Hand 90deg; C: 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.
