1. Barrier

It refers to the barrier properties of water vapor and oxygen in the environment. The poor barrier properties caused by the defects of aluminum foil itself will cause the medicine’s quality problem during the shelf life.

2. Heat sealing performance

It is verified by the heat sealing strength test. If the heat sealing strength of the blister package is poor, the sealing effect of the medicine will be poor, causing gas to easily enter the blister from the poor heat sealing place, which cause the deliquescence and oxidation of the medicine.
