PACKAGING UNPACKED Table-grape packaging is a system in which all the components must work together to maintain quality and prevent decay.

BY ANNA MOUTON

From inside to outside, table-grape packaging can include a bunch carrier, a SO 2 sheet, a moisture-absorbing sheet, a shock-absorbing sheet, a liner, and a carton. The performance of each component will affect the overall success of the system. The influence of packaging on ventilation is critical. Too little ventilation increases the risk of SO 2 damage and excessive humidity. The latter contributes to berry split and decay, especially if cold-chain breaks cause condensation. Too much ventilation increases dehydration, leading to mass loss, berry drop, and stem browning, and lowers SO 2 levels, reducing decay control.
