Measuring The Hardness Of Blister Packs To Determine Effectiveness

The increasing use of blister packs for unit dose packaging of tablets, capsules or lozenges in the pharmaceutical industry demands for good quality packaging. Blister packs should provide some degree of tamper resistance avoiding accidental opening during transportation and by children. A quality blister pack should be consistent in the force required to extract the tablet and easily opened by weaker patients and the elderly. The degree of stiffness of a blister pack will however affect its effectiveness. Measuring the required force to push-through a blister pack is therefore necessary.
