ABSTRACT:
A moulded plastics article, such as a container, having a blank of a plastics film material, as a label or diffusion barrier, at a surface thereof is manufactured by a method including the steps of cutting blanks individually from a strip of the plastics film material for each moulding operation, and feeding each cut blank to and introducing it into the mould ready for the respective moulding operation to be performed in which the blank becomes incorporated in the moulded article. The blank may be located in the mould by suction and/or blown air applied at the mould, or by electrostatically charging the blank to cause it to be attracted to a surface in the mould. The cut blanks are taken individually to the mould by a transfer arm which holds them by suction.
