Abstract
Packaging/storage shaped articles, for example, opaque bottles suited for storing and shielding such products as milk away from the adverse effects of visible and UV radiation, are manufactured by first providing/formulating precursor compositions which include a polyester or polylactone thermoplastic matrix having at least one mineral filler distributed therethrough, the mineral filler containing a titanium oxide and/or zinc sulfide and also having from 2% to 40% by weight of the composition, and thence converting the composition into such packaging/storage shaped article, notably by injection-blow molding.
