Abstract (en)
[origin: EP0380269A2] A method of treating a food container having a plastics body portion and a lid sealed thereto for the purpose of ensuring that micro-organisms cannot penetrate into the interior of the container through any faults or imperfections in the seal between the lid and the body portion, which method comprises forming a polymeric coating layer over the external surface of the container in such a manner as to encompass completely the join between the lid and the body of the container, the resultant polymeric coating layer being a retortable polymer. The method of the invention provides a substantial reduction in the number of failures of the seal between the lid and body portion of plastics containers for foodstuffs.
