A packaging apparatus for wrapping a carton around a packaged product comprises a box mandrel conveyor including a plurality of mandrels which support the packaged product thereon. Packages are precisely fed to the mandrels of the box mandrel conveyor by a conditioning conveyor. Carton blanks are delivered to a conveying system from a carton magazine and are conveyed in vertical confronting relation to a mandrel. Each mandrel moves the carton blank against a plow device thereby causing the carton blank to be folded around a mandrel containing a package. Folding and compression devices are provided for folding and compressing an end panel against a manufacturer's flap. Suitable flap closing means close the end flaps and upper and lower flaps after the mandrel is withdrawn from the carton.
