Capping And Lamination Of Tablets

The term tablet capping is used when either the upper or lower part of the tablet separates horizontally either partially away from the main body or completely to form a cap when ejected from the press or during the handling process.

Capping and lamination of tablets.

First lamination is caused by air being trapped in the tablet especially among the granules or particles. Lamination is separation that occurs at any other part of the tablet except the top or bottom. Capping and lamination are common defects that occur during tablet manufacturing. Although the method is widely used there are still significant challenges with achieving a high quality compact.

Tablet capping and lamination powder compaction is widely used to produce pharmaceutical tablets and is referred to as a tabletting process. Lamination is also caused by the presence of a large amount of fines in the granulations. Capping happens when the upper or lower part of a tablet separates horizontally photo as the press ejects the tablet. Ejection issues could lead to lamination.

This challenge can be overcome by doing a pre compression as well as reducing the compression and minimizing the tableting rate.
