Abstract (en)
The invention relates to a cardboard-made bag-like package and a method for the fabrication thereof. The package is fabricated of two separate cardboard sheets (1, 2) of which the longer and narrower cardboard sheet (1) is double-folded along a folding line (5) that forms the package bottom. The shorter and wider cardboard sheet (2) is adhered to one of the folded halves of longer cardboard sheet (1) in order to provide the package with a double wall. from whose top edge the end zone (4) of longer cardboard sheet (1) extends for forming a package closing flap. Side strips (3) of shorter cardboard sheet (2) are folded around the side edges of the other folded half of longer cardboard sheet (1) and adhered to its outer surface. The package can be fabricated at a high rate of production from cardboard webs delivered from supply rollers without cutting waste pieces.
