Abstract
The invention is directed to novel packages and to a method and device for producing packing coverings for composite cardboard/plastic packages. Specifically, beverage packages that include an opening for pouring and/or removing the product contained therein. The method incorporates a reliable solution to prevent contact between the contained product and the raw cardboard material in an area proximate to the opening during storage, after the package is opened for the first time, and after resealing of the opening. In variations of the package and its method of making, the cardboard is punched with an opening defined by a circular edge. The edge and the raw cardboard are coated with a plastic material, and a smaller pour opening is centrally punched inside the punched opening leaving the circular edge sealed by the plastic coating. The package is then creased, seamed, folded, and than later sterilized, filled, and sealed.
