Agricultural films are typically thin - often between 8 andd 40 microns - and means brittle after UV exposure. Thi make them prone to tearing during mechanical collection. The degraded polymer chain lengths reducte mechanical comperties, so recycled material from traditional methods often performs poorly compared to to virgin resin.

Furthermore, recykling infrastructure is typically optimized for rigid plastics (bottles, conteers) rather than explible, requiring retrofiting or entirecirely new processings.
