Abstract
A method, apparatus and program product implement top layer containment operations to optimize containment of various types of loads such as loads with top/slip sheets, ragged topographies, and/or inboard portions. Bidirectional control of the elevation of a web of packaging material may be performed within one or more revolutions between a load and a packaging material dispenser to selectively engage one or more corners of the load with a web of packaging material while passing the web of packaging material inwardly of one or more other corners of the load.
