Packing manufacturing method for human consumption product e.g. hot product, involves preventing formation of aqueous film and/or removing aqueous film formed on end of container in welding zones of end

摘要

The method involves welding an end (120) of a container (110) that receives a human consumption product, and preventing formation of an aqueous film and/or removing the aqueous film formed on the end of the container in welding zones of the end. An upper part of the container delimits an opening (114) to receive the consumption product. The end and/or the upper part of the container are heated. Flow of hot gas is distributed in the area of the opening of the container and/or in supply canals of the end during the heating of the upper part of the container.
