A recyclable, laminated polyolefin-based film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin-based films. The film structure has an energy-cured coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin-based polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin-based film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin-based film structure.

Recyclable laminated polyolefin-based film structures

A recyclable, laminated polyolefin film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin films. The film structure has an energy cured coating layer or a two-part coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 150 or 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin film structure.

In one aspect, a pouch includes a first panel, a second panel, and a bottom gusset, wherein the first panel, second panel, and bottom gusset are formed of a polyester-based film structure and wherein the bending stiffness of the bottom gusset panel is less than or equal to 0.05 N/mm. Each of the polyester-based film structures may be formed of a polyester-based polymeric composition comprising polybutylene terephthalate (PBT), polyethylene terephthalate (PET), or a blend from 0-100% by weight of PBT in PET. It is contemplated that each polyester-based film structure may comprise two or more film plies laminated to each other.

Recycle-ready retortable laminated polyester-based gusseted pouches

A recyclable packaging film comprising a coextruded web having a high degree of optical clarity and a high level of moisture barrier. The coextruded web comprises a skin layer comprising polyethylene having a high degree of optical clarity and a heat sealant layer which forms an innermost layer of the packaging film, the heat sealant layer comprising a polyolefin polymer. The coextruded web also includes a moisture barrier layer which is disposed intermediate the skin layer and the heat sealant layer. An energy-cured coating is disposed on the skin layer of the coextruded web, wherein the energy-cured coating has a coating weight which is effective to impart a property in the packaging film selected from reduced susceptibility to melting, reduced susceptibility to stretching, or both.
