Fiber-based containerboard is an excellent material for designing dependable, renewable, and fully circular berry packaging. Corrugated containerboard packaging is fit for not just berry trays, but for individually packaged portions where plastic punnets are commonly used. On top of this, the packaging can be easily designed to showcase the visual appeal of berries without needing a fully see-through concept.
To help berry packagers and retailers understand key differences in the sustainability performance of consumer berry packaging, we recently conducted a Life Cycle Assessment (LCA) comparing packages made from fresh fiber-based corrugated containerboard to packages made from recycled PET.
Fiber-based or PET: assessing the impactThe packages studied featured a 500g capacity and rigid lid containing strawberries, tomatoes, or similar produce transported within Germany. The corrugated package is the EcoFresh box by Stora Enso with a lid, produced from AvantForte Brown kraftliner and AvantForte SC+ fluting. The plastic alternative is a comparable package made of recycled PET.
The findings revealed:
Overall, when a corrugated punnet is compared with a recycled PET punnet, the corrugated system shows environmental benefits in 11 out of 13 environmental impact categories, and the climate change benefits were consistent throughout the sensitivity analysis.
