A Comparative Assessment of the Shelf-Life of Tomatoes in Paperboard and Plastic Punnet Trays
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.
However alternative packaging materials and formats must still be fit for purpose. For applications like fresh produce, packaging must protect the delicate items and offer a shelf life that’s at least equivalent to plastic.
So, do paperboard punnet trays for fresh produce applications deliver an equivalent shelf-life to traditional plastic punnet trays? This study conducted by Washington State University set out to determine just that.

** Directional cradle to gate carbon footprint. For the paperboard punnet tray, it includes: board type and weight with emission factors based on supplier primary data following CEPI 10 toes methodology (valid until 2028-10-13), data for conversion based on average scope 1 and 2 emissions from all Graphic Packaging converting sites in the region (as calculated by limited independent third‑party assurance in accordance with ISAE 3000 and 3410), data for ink and varnish from industry averages. Sheet waste generated during conversion is included. It would be later recycled leading to credits in a cradle to grave analysis. Inbound and outbound transport is symmetrically assumed to be 500 km by truck for the two compared cases. In the case of the PET tray, Gabi LCA Packaging Calculator (2024 Sphera database) was used and excludes, any converting waste and any additional materials used in the PET packaging, e.g. labels, sealing layer etc. The model uses industry average data and is consistent with international standards ISO 14040 and ISO 14044.
