ABSTRACT:
A process for lining container caps, which comprises applying a dispersion in an aqueous medium of an olefin resin to the inner bottom surface of a cap shell, subjecting the aqueous dispersion applied to a first-step heat treatment at a temperature below the thermo-forming temperature of the olefin resin, and then subjecting it to a second-step heat treatment at a temperature not lower than the thermo-forming temperature of the resin but below the heat decomposition temperature of the resin.
