Method for forming a band seal on a capsule

摘要

A method of producing a capsule including forming a band seal between a cap and a body of the filled capsule when the cap has been fitted onto the body, by one or more applications of gelatin-based sealant in the form of a band spanning the cap surface and body surface across the edge of the cap, to form one or more corresponding band seal layers securing between the cap and body; characterised in that for said application of sealant, or for at least the first application where there are more than one, the gelatin-based sealant is one whose viscosity at 50 DEG C is from 50 to 200 mPa.s (centipoise)..
