A film or hollow shaped article prepared from a low PETN copolymer resin wherein the resin has at least one of (a) an oxygen permeability of less than 2000 cc- mu m/m<2>-day-atmos at 30 DEG C; (b) a density of greater than 1.3400 g/cm<3>; or an area of the peak in tan delta centred at T beta of less than 75 % of that for PET. Such articles have improved gas barrier performance, particularly impermeability to oxygen. |
