Fresh produce packaging keeps evolving as growers, packers, and retailers strive to stay competitive amid changing market demands. Shifting consumer preferences, corporate sustainability goals, and tightening regulatory restrictions on single-use plastics are fueling a transition toward paperboard alternatives.
