Abstract
A stretch wrap applicator includes a member designed to engage the stretch wrap or stretch film as it is dispensed and to deform the stretch wrap by creating additional pockets of stretch on the stretch wrap transverse to its plane. The additional deformations caused by the member engaging the stretch wrap whether done in-line using the applicator or offline using equipment effects an additional stretch of the stretch film during application beyond the typical stretch caused by tension on stretch wrap when being applied to an object.
