FIELD: equipment for making paper articles.

SUBSTANCE: package is produced of laminated packing material formed of cellulose pulp and having three-dimensional layer which gives a three-dimensional configuration to the package, and at least one side layer formed on one side of three-dimensional layer. Side and three-dimensional layers are directly or indirectly connected one to another over the full surfaces thereof facing each other. Method for package production by creasing and folding laminated packing material involves pressing creasing device in one side of laminated packing material to form crease lines and holding the packing material by supporting tool from opposite side thereof, wherein the supporting tool is substantially flat in area corresponding to area of creasing device application; folding the packing material about crease line. Above three-dimensional layer has latticed structure formed of cellulose fibers.

EFFECT: decreased thickness of obtained package, possibility to fold packing material through 180° in which total thickness of folded material is approximately equal to double unfolded material thickness.
