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.
Claims9
A method for manufacturing a recyclable flexible packaging film, comprising:
- crosslinking a portion of a polyethylene film using electron beam (EB) radiation to obtain an EB crosslinked polyethylene film;
- stretching the EB crosslinked polyethylene film to obtain an oriented film, a stretched thickness of the portion being less than 10% of a thickness of the oriented film;
- and
- laminating the oriented film to a sealant polyethylene film using an adhesive,
- wherein the electron beam radiation is applied at 70-85 kV.
