Claim:
1. A method for banding a hydroxypropylmethyl cellulose (HPMC) hard capsule having a body and a cap with the inner circumference of said cap at its edge being greater than the outer circumference of the capsule body, said method comprising: providing said HPMC hard capsule; and contacting the juncture of the cap and body edge of said HPMC hard capsule with a banding composition, the banding composition comprising: (1) low viscosity HPMC present in the banding composition in an amount of more than 15% by weight based on the entire weight of the banding composition, the low viscosity HPMC having a viscosity in the form of a 2% aqueous solution of not more than 15 centipoise at 20° C.; (2) a component selected from the group consisting of methanol, ethanol, isopropanol, 1-propanol, and/or acetone and mixtures of two or more of the foregoing, (3) a surfactant selected from the group consisting of sorbitan fatty acid esters, sucrose fatty acid esters, polyoxyethylene fatty acid esters, and sodium lauryl sulfate; (4) water, wherein the proportion of component (2) and water (4) is in a range of from 40:60 to 60:40% by weight; forming a continuous band locally at the juncture of the cap and body edge of the capsule with the banding composition; and drying the sealed capsule.
