Seal Strength Tester
Seal strength testing evaluates the mechanical strength of the seal, assuring proper bonding to maintain package integrity throughout the life of the package. Here we address two basic typle of seal strength testing: tensile strength testing (ASTM F88) and burst or crepp testing (ASTM F1140 & ASTM F2054)
Tensile Seal Strength Testing - Tensile Strength Testers
One-inch wide samples are cut perpendicular to the seal and pulled apart at a constant speed (usually 12 inches/minute) when mounted in the grippers of the instrument. The force required to separate the two sealed substrates is measured and reported as x lbs/inch width.
- ASTM F88 -- Standard Test Method for Seal Strength of Flexible Barrier Materials
Burst and Creep Testing - LSSD-01 Leak and Seal Strength Detector
- Burst Test: Fill the package with air until it bursts and measuring the terminal pressure.The method can be used with the package unrestrained or within restraining plastes to simulate packages stressed in various situations.
- Creep Test: Inflate the package to a constant pressure and then check if the pressure in the package can hold a specific time. the suggested pressure in
ASTM F1140 is about 80% of burst pressure.
ASTM F1140 -- Standard Test Methods for Internal Pressurization Failure Resistance of Unrestrained Packages for Medical Applications
ASTM F2054 -- Standard Test Method for Burst Testing of Flexible Package Seals Using Internal Air Pressurization within Restraining Plates
