Band. The area between opposing tablet cup profiles that is formed by the wall of a tablet die; also a liquid seal that is applied around the joint of filled two-piece capsules. Banding. The process of applying a band around the joint of two-piece capsules filled with powders or liquids to provide tamper evidence and to prevent leakage. Bar code. A way of labeling a product with a description and batch information using a series of lines of varying thicknesses that is read by a scanner. It comes in multiple formats, including 2-D matrix codes. Barrier. Used to describe packaging material properties that prevent moisture and/or oxygen from coming into contact with products. Batch operation. A method by which one lot of a formulation is processed at a time, in contrast to continuous operation. Bi-layer tablet. A tablet comprising two distinct layers. Binder. An excipient used to increase powder cohesiveness, which increases the bonding strength of the final product. In wet granulation, they help form agglomerates. Bioavailability. A measure of the uptake of an API by the body, including the rate at which and extent to which it is absorbed or is available at the treatment site. Bioequivalence. The absence of a significant difference in the rate and extent to which an API becomes available at the site of action when two different drug products are adminis- tered at the same dose under similar conditions. The basis by which generic drug products are approved by comparing them to the brand-name product. Biopharmaceutics Classification System (BCS). A four-quadrant system of classifying the solubility and absorption rate characteristics of a drug substance. Bisect/score. A groove or debossed line in the tablet surface that controls stress fracturing. It also allows the tablet to be split into pieces for partial dosages. Blister. A cavity formed in film or foil by heat and/or mechanical means. Blister pack. A package that comprises one or more blisters filled with tablets or capsules and sealed with film or foil lidstock.

Adhesion. A molecular attraction between different materi- als, such as a metal surface and powder. Agglomerate. Noun. The product of size enlargement, such as a granule. A group of particles held together at their points of contact by solid bridges. Verb. The process of forming fine particles into permanent larger shapes in which individual particles can still be distinguished. Aggregate. A group of particles held together by weak elec- trostatic and Van der Waals forces. Agitation. A type of particle size enlargement without the use of pressure, either by tumbling, coalescence, or particle growth. Air vents. Channels located at the cut-edge of a capsule body that allow air to escape during capsule closing. Assay. A laboratory test that identifies or measures the amount of a substance in a sample and helps determine its characteristics, such as potency and/or purity. Atomization. The process of creating a fine, controlled mist by passing air and a solution through a nozzle; used for film coating, wet granulation, and spray drying. Attrition. The process of tumbling an agglomerate to deter- mine its resistance to surface abrasion. B Balcony-style design. A cantilever configuration of machines, such as blister packaging equipment, that facili- tates access for changeover, cleaning, and maintenance. glossary of formulation, production, and packaging terms g l o s s a r y o f t e r m s Tablets & Capsules November 2018 47
