Abstract:
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.
