Peel Testing / Seal Strength

Guidance Documents –

ISO 11607

ASTM F88 –Standard Test Method for Seal Strength of Flexible Barrier Materials

What is it?

Peel Testing, also known as Seal Strength Testing, measures the strength of seals within flexible barrier materials. This measurement can then be used to determine consistency within the seal, as well as evaluation of the opening force of the package system.

One-inch wide test specimens are cut from a sealed package and placed in a tensile test machine. The specimen is pulled in tension and the force required to separate the specimen is recorded.

Why do it?

Peel testing is used to measure and quantify the strength of Medical Device Package Sterile Barrier Systems as well as other sealed flexible packages.
The seal peel tensile test determines the strength of the seal at a specific place on the package which can be helpful in setting the sealing parameters.
Assures you that your medical device packaging is sterile an easy to open and helps avoid costly recalls due to seal failures.
Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals.
