Sterilization is a major part of the medical device manufacturing industry. Therefore, manufacturers take care to produce properly sealed medical packaging. Our engineers are familiar with the ASTM F88 test procedure and can guide you through the process and help you choose the best equipment.
We also recommend that you purchase the ASTM F88 standard and follow it closely to achieve the best results. ASTM F88 is a testing standard for measurement of seal strength for flexible barrier materials in medical packaging. Seal strength is not only relevant to opening force and package integrity, but for measuring the packaging processes. It is common for confusion to arise regarding the difference between package seal strength and package integrity.
Seal strength relates to the force required to separate two flexible components of the package. This can be measured through a peel test using a Peel Tester. Alone, this does not prove the integrity of the entire package, only the integrity of the seal strength of two components. Although further testing of the entire package may be necessary, the main cause for failing package strength tends to be through the seal.
Cut a one inch wide strip of the seal from each of the 4 sides of the package with a TestResources sample cutter. Clamp each leg of the test specimen in a Peel Tester. Align the more rigid side of the sample to be clamped in the top grip. For each cycle, report the maximum force as the specimen is stressed to failure and identify the type of failure.
In ASTM F88 it is useful to know that Figure 1 describes three configurations for the test, but there are only two in reality. Also, our engineers recommend pneumatic grips for ASTM F88 because the specimen ends must be aligned such that the peel interface is accurately perpendicular to the load center of the peel test machine. This accurate alignment is easier to achieve with pneumatic grips than with mechanical grips because mechanical grips must be twisted to tighten. The P consists of a vertical load frame, an electromechanical actuator, load cell, a tocuhpad test controller, XY test software and peel grips.
We would configure a small capacity load cell 10 or 25 pound for this low force peel test. A 10 lb load cell can be calibrated to measure 0. The peel plot will be an important aspect of data retrieval and therefore we highly recommend our XyPlot software. If you would rather see the data in real-time and study the peel interface at the same time, we would provide you with our XyLive Software. In order to get the best results from your peel testing, grips are an essential part of your purchase.
These are a lower cost option and produce great results. You may also consider purchasing pneumatic grips. Pneumatic grips are helpful in getting the specimen well-aligned in the grips due to the foot activator giving you both hands free to hold the specimen. It is not easy to hold the specimen exactly perpendicular in the grips while you are cranking a manual vice grip. Give one of our engineers a call today and they can help guide you through the ASTM F88 test process with the best machine configuration for your requirements.

Seal Strength ASTM F88
Learn more. 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 material containing the seal. The mode of failure is also identified.

Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More F Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes' ability to produce consistent seals. 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 number of fixtures and techniques have been devised to hold samples at various angles to the pull direction to control this bending force. 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.
