Capping And Lamination Definition

Lamination is the term used for a split in the tablet anywhere but at the top.

Capping and lamination definition.

The practice of selling large amounts of a commodity or security close to the options expiry date in order to prevent a rise in market price. Main reason for lamination is attributed to presence of bands cracks in tablet whereas presence of air in. Capping in tablets during the compression is a major problem in tablet manufacturing. Some causes and solutions of the capping of tablets are given here.

Ankur choudhary print question forum 3 comments when the top of a tablet separates from rest of its body it is called tablet capping. Capping happens when air is trapped within the tablet during the compression. Lamination laminating 1 5 definition. Air entrapment efficiency of the powders is one of the main factors leading to occurrence of capping or lamination tendency of tablets manufactured from the directly compressible powder blends.

Chipping is a defect related arising due to very dry granules. 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. J hooks are the distinctive wear patterns on punch tips that are a cause of such tablet defects as capping lamination and poor friability. Lamination is the separation of a tablet into two or more distinct horizontal layers.

This challenge can be overcome by doing a pre compression as well as reducing the compression and minimizing the tableting rate. Capping is usually easy to fix either by increasing the dwell time i e slowing down the production or by careful analysis of the formulation and production process. Lamination is also caused by the presence of a large amount of fines in the granulations. Lamination is essentially the same as capping and with similar causes.

Anyone who has experienced capping or lamination during tablet production knows the frustration that comes from trying to diagnose the issue. First lamination is caused by air being trapped in the tablet especially among the granules or particles. Usually capping and lamination occur during or after tablet manufacturing and may therefore influence follow up processes such as the coating. The purpose of the current research was to study this underlying cause leading to occurrence of capping or lamination of tablets through evaluation of powder rheological properties.

In this context there is an urgent need for approaches to overcome the occurrences of capping and lamination. In this article we discuss a possible cause and several solutions.
