Laser-cuttable polyolefin shrink wrap

Last updated:

Abstract:

Polyolefin shrink-wrap films may include a light-absorption additive to make them laser-cuttable by commonly-available lasers. This can make them more amenable to alteration by laser after being shrink-wrapped around a product package, such as alteration to remove sections of the polyolefin shrink-wrap film or to create tabs or perforations to facilitate removal of the polyolefin shrink-wrap film.
