1. A method of manufacturing a golf ball having a moisture vapor barrier layer, comprising the steps of:
a) forming a core;
b) forming a moisture vapor barrier layer that encapsulates the inner core by depositing non-ionomeric polyolefin powder particulate onto the core, the powder particulate having a particle size less than about 100 microns, heating the deposited particles to form a continuous coating, and cooling the coating; and
c) forming a cover layer over the moisture vapor barrier layer by powder coating the composition for the cover layer directly onto the moisture vapor barrier layer.
