A composite packaging is a packaging consisting of an outer packaging and an inner receptacle constructed so that the inner receptacle and the outer packaging form one integral packaging. Once assembled, a composite packaging remains an integrated, single unit – it is filled, stored, shipped, and emptied as a single unit. By contrast, a combination packaging consists of one or more inner packagings secured in a non-bulk outer packaging. The inner packaging of a combination packaging is intended to be removed from the outer packaging for emptying. The inner receptacle for the packaging described in the question above can be used as either an integral component of the packaging or a separate inner packaging of a combination packaging. We consider such a packaging to be a combination packaging because the inner packaging may be removed for emptying. A composite packaging must be filled and emptied as a single unit.
