When a sticking defect is noticed on a tablet, one must first identify where the sticking is occurring (upper punch, lower punch or both). The location of the sticking/picking will help in identifying the root cause. There are as many causes of sticking and picking as there are formulations. A few of the most common are …

reducing the overall stroke depth of the embossing and will assist you in keeping a clear brand identity. 'Sticking' of course is another major issue in the design and manufacture of tablets. Sticking differs to picking in that it is gran ule adherence to the punch tip face, rather than in and around the embossing.

It is generally better to run minimal upper-punch penetration (to help prevent air entrapment) and to reduce tablet ejection travel in the die bore. This practice also reduces lower punch movement, which generates heat. Heat is the enemy, because it increases sticking and picking issues.

Deep cup profiles can cause a softer core in the tablet which can in turn lead to sticking. It will also reduce the available space for the embossing itself; the use of a profile that is shallower, with a reduced cup depth, will allow for a larger embossing area.

In this case, there are two possibilities to remedy the problem. The first remedy is to reduce the amount of binder used in the manufacturing process. Alternatively, the binder in question can also be changed so as to prevent the tablet sticking problem. Moreover, tablet sticking is also brought up by hygroscopic granular materials.

High bonding indices could also indicate sticking and picking problems during tableting 14, 32. A material with a higher BI forms stronger compacts, which survive the die wall and ejection forces, whereas a material with a low BI may produce friable tablets 37. In general, the values of BI range from 0 to 0.04.
