A method and apparatus for packing a box or other product is disclosed which involves wrapping a packing sheet about the product in an improved fashion. The method includes lapping the packing sheet around the product, folding opposed side edges of end portions of the packing sheet over ends of the product and folding upper and lower edges of the folded end portions of the sheet over the product ends. The upper edges of the sheet are folded upwardly at the same time that side edges are folded over at least one end of the product. Upper and lower edges of the end portions are then folded over the product ends and attached to each other. The apparatus for performing the method includes a packing sheet lapping section, a product transfer path located adjacent to a leading side of the lapping section, a pusher positioned adjacent to a trailing side of the lapping section and a plurality of folding elements. Separate folding structure is provided for folding opposed side edges of the packing sheet end portions over the ends of the product while also upwardly folding upper edges of the end portions, for folding lower edges of the end portions over the ends of the product and for folding the upwardly folded upper edges of the end portions over the ends of the product. The structure for folding the opposed side edges and upper edges of the packing sheet end portions can be stationary, moveable in a straight line, pivoted or swinging. The upper edges of the end portions can be upwardly folded by folding structure located at both sides of the packing sheet lapping section or folding structure located at only one side of the lapping section.
