Abstract
Disclosed herein is a novel, sustainable and recyclable flexible packaging film used for the purpose of food and non-food packaging. The invention also relates to improved method of manufacturing the recyclable flexible packaging film which results in enhanced recyclability of the film.
Claims19
A method for manufacturing a recyclable flexible packaging film, the method characterized by:
- a) crosslinking at least a portion of a polyethylene film using electron beam (EB) radiation to obtain an EB crosslinked polyethylene film having a thickness comprising a crosslinked layer;
- b) stretching the EB crosslinked polyethylene film to obtain an oriented film, a stretched thickness of the oriented film having the crosslinked layer being less than 10% of the stretched thickness;
- and
- c) laminating the oriented film to a sealant polyethylene film using an adhesive.
1 more element
A recyclable flexible package (100) comprising:
- a) a substrate layer (102) comprising a polyethylene (PE) film;
- and
- b) a sealant layer (106) comprising a sealant polyethylene film,
- wherein the sealant polyethylene film is disposed over the substrate layer using an adhesive (104),
- wherein at least a portion of the substrate layer (102) is EB crosslinked to obtain an EB crosslinked substrate layer having a thickness comprising a crosslinked layer and the substrate layer (102) is stretched, a stretched thickness of the crosslinked layer being less than 10% of a thickness of the stretched substrate layer.
