Compostable packs ‘may allow longer shelf-life’ of vegetables than plastic, studies find

Compostable packaging could be as effective as conventional plastic and may even outperform it for shelf-life of fresh produce, according to two peer reviewed studies commissioned by TIPA.

The compostable packaging specialist said scientists at the Agricultural Research Organization (ARO), The Volcani Institute (Israel), found compostable packaging enables shelf-life of bell peppers up to 21 days and cucumbers up to 15 days, even better than conventional plastic.

Researchers used cucumbers and bell peppers to test the differences between compostable packaging and conventional plastic packaging.

Both types of packaging allowed keeping bell peppers for four weeks, and cucumbers for two weeks in refrigerated home storage. In addition, properly designed micro-perforated compostable packages extended the non-refrigerated shelf life of cucumbers up to 15 days, compared to not more than 10 days in conventional plastic packs.

An additional advantage of the compostable packaging was the prevention of water condensation that encourages the rotting of vegetables wrapped in conventional plastics. The compostable packages used in the studies were purchased from TIPA Corp.
