Two peer-reviewed studies commissioned by TIPA seem to suggest that compostable packaging may be as effective as, or even outperform, conventional plastic in terms of shelf life of fresh produce. The compostable packaging specialist said, scientists from the Agricultural Research Organization (ARO), The Volcani Institute (Israel), found that compostable packaging allows bell peppers to last up to 21 days and cucumbers up to 15 days. These are better numbers than with conventional plastic.
Researcher used cucumbers and peppers to test the differences between compostable packaging and traditional plastic packaging. Both types of packaging made it possible to keep peppers for four weeks and cucumbers for two weeks in the cold store. In addition, properly designed micro-perforated compostable packaging extended the uncooled shelf life of cucumbers to up to 15 days, compared to no more than 10 days in conventional plastic packaging.
Another advantage of the compostable packaging was the avoidance of water condensation, which encourages the rotting of vegetables wrapped in conventional plastic. The compostable packaging used in the studies was provided by TIPA Corp.
