Seal Strength

Seal Strength of medical packages is measured using a strain gauge test instrument such as an Instron testing system or Chatillon gauge or testing instrument 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
