A method for wrapping a load with a film, strip, band of extensible material comprises: unwinding a film of extensible material from a reel; making a pleat on the film by means of a pleating system; stretching the film by means of a pair of pre-stretching rollers; welding the pleat by means of at least one of the pre-stretching rollers; wrapping the load with the film provided with the pleat.

A method, apparatus and program product may utilize packaging material quality compensation to sense changes in certain characteristics of a packaging material that can be associated with increased risks of film breaks, and automatically make certain changes in machine settings to mitigate the impact of those enhanced risks.

A rotary translational strapping apparatus and strapping method thereof are provided including a support frame, a rotary module, and a translational strapping module, the rotary module includes a rotary guide, a rotary frame, and a first driving mechanism, the rotary guide is disposed on top of the support frame, the rotary frame is rotatably disposed on the rotary guide, the first driving mechanism is used for driving the rotary frame to rotate relative to the rotary guide. The translational strapping module includes a sliding mount, a strapping head, a strapping chute, and a second driving mechanism. The sliding mount is slidably disposed on the rotary frame.

Various embodiments of the present disclosure provide a stretch-wrapping machine with self-adjusting pinch rollers configured to reorient themselves to compensate for misalignment relative to their respective pre-stretch rollers. This ensures the pinch rollers press the entire width of the film against their respective pre-stretch rollers as the film is drawn through the rollers.

A plastic film bundle, and apparatus and methods for forming the plastic film bundle are disclosed herein.

Control of a load wrapping apparatus may be based at least in part on the relative stability of a load, such as based upon one or more load stability types that categorize the relative stability of the load. A graphical depiction of a wrap profile may also be used in some instances to facilitate operator set up of the wrap profile.
