PCR content film blends mechanically recycled post-consumer polyethylene into a structure alongside virgin resin, at a percentage driven by the customer's sustainability targets and the performance the application can tolerate. PCR percentages in commercial film commonly range from a modest 10 to 30 percent up to 100 percent for less demanding applications, with the right number depending on what the package needs to survive.
Reclaimed resin carries more variability than virgin resin: melt index, color, gel content, and odor can all shift between PCR lots depending on the source stream and the reclaimer's processing quality. This generally means a PCR structure runs with a wider acceptable tolerance band on optical and mechanical properties than an equivalent virgin structure, and it often benefits from a coextruded design that places PCR content in a core layer while virgin resin handles the seal and outer surfaces where consistency matters most. Buyers should set realistic expectations on clarity and color consistency when specifying higher PCR percentages, since these are the properties most visibly affected by reclaimed content.
