Abstract
A recyclable flexible package used for foods, non-foods, pharmaceuticals, and other products that would benefit from flexible packaging solutions is provided. The present invention also relates to the methods of forming recyclable flexible packaging using fewer production steps while using EB cured inks & EB laminates, among others.
Claims23
A recyclable flexible package comprising:
- an Electron Beam (EB) treated oriented, cross-linked polyethylene (OPE) film;
- at least one reverse printed EB ink layer;
- a laminating layer;
- and
- a sealant polyethylene film.
2 more elements
A method of forming a recyclable flexible package, the method comprising:
- applying at least one reverse printed Electron Beam (EB) ink layer to an EB treated oriented polyethylene (OPE) film;
- curing the at least one reverse printed EB ink layer and the EB treated OPE film by electron beam radiation, to cause the OPE film to become cross-linked;
- and laminating a sealant polyethylene film to the at least one reverse printed EB ink layer by use of a laminating layer between the reverse printed EB ink layer and the sealant polyethylene film, to form the recyclable flexible package.
A recyclable flexible package consisting of:
- an Electron Beam (EB) treated oriented, cross-linked polyethylene (OPE) film;
- a reverse printed EB ink layer disposed over the EB treated OPE film;
- a laminating layer disposed over the at least one reverse printed EB ink layer;
- and a sealant polyethylene film disposed over the laminating layer.
