Seal Strength Testing Equipment

Seal strength is a useful measure to help predict the final integrity of a package. It ensures the package can provide and maintain a barrier for the product for sterility, freshness and overall quality performance. This testing also proves the packaging processes’ ability to produce consistent seals, especially those made from thin plastic sheets or similar flexible material.

The test is a combination of a tensile test and an adhesive test. Testing equipment for measuring seal strength measures the force required to separate or break the layers of a packaging seal when under tension. ASTM F88 is the most common test method used to measure and quantify the strength of the seal of flexible materials.

Applications that require evaluation of heated seals should be prepared using a suitable heat sealer with the provision to control the temperature, dwell time, and pressure of the sealing dies, as this can affect the ultimate strength of the heat seal.
