Abstract

Hollow moulded polypropylene articles are produced by (a) extruding a molten polypropylene tube, (b) rapidly cooling the internal and external surfaces of this tube to a temp. below the crystallisation temp. thus producing rapid crystallisation of the cooled portion, (c) cutting the tube into at least two predetermined lengths, (d) heating the cut lengths of tube, (e) drawing each of the heated lengths in an axial direction at a temp. above the crystalline m.p. and below the thermal m.p. (f) placing each of the drawn lengths in a mould, and (g) injecting a pressurised fluid into each of the lengths, in order to expand the lengths against the inside of the mould. Articles are smooth with high transparency.
