A stretch film supply roll used in stretch wrapping palletized loads includes a plurality of lengths of stretch film wound into a roll form and joined to one another using a plurality of lap seals that forms a continuous web of stretch film on the roll form. Such a stretch film supply roll may be useful, for example, in reuse applications where stretch film is reused multiple times to wrap different loads. In some instances, the lengths of stretch film may have been used to previously wrap different loads, and in some instances, the lengths of stretch film may have differing characteristics such as materials and/or thicknesses

A method and unwrapping apparatus collect stretch film spirally wrapped around a load by generating relative rotation between a take up device and the load over a plurality of relative rotations between the take up device and the load. In some instances, the collected stretch film may be recycled, while in other instances, the collected stretch film may be reused to wrap another load.

A stretch wrapping apparatus, unwrapping apparatus, system, and/or method suitable for use in recycling and/or reuse applications associated with palletized loads that are wrapped with stretch film. In recycling applications, various unwrapping apparatus designs may be utilized to collect stretch film spirally wrapped around a load, generally by unwrapping the stretch film over the course of multiple revolutions. In reuse applications, various stretch wrapping apparatus designs may be used to wrap stretch film around a load in a manner that conditions the stretch film for reusability, while various unwrapping apparatus designs may be utilized to collect the stretch film from a load into a roll form that is suitable for use in wrapping other loads.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. A test apparatus may be used to evaluate packaging material using a take up drum capable of sensing containment force imparted upon the drum by packaging material applied thereto, and in some instances, simulated flaws may be formed in a web of packaging material to evaluate a packaging materials response to such flaws when under tension.
