The effect of ICI "Lifespan" carton liners on the quality of Navel and Valencia oranges, Imperial and Ellendale mandarins and lemons was determined and compared with packing and storing fruits in conventional cartons. A protocol involving careful harvest, prompt fungicide treatment and optimal storage temperatures was developed to minimize mould wastage and development of rind blemishes. A trial shipment to Singapore of Navel oranges packed in carton liners showed that fruits retained their shape and fresh appearance due to control of weight loss without significantly increased mould wastage, but importers still preferred overfilled packages of fruits without carton liners. Valencia oranges and lemons packed in carton liners were of fresh appearance after 12 weeks of storage, losing <1% weight compared with 9% from non-lined packages. Imperial mandarins packed in plastic liners and held at 5 deg C had a storage life of only 4 weeks due to loss of flavour. Lemons and mandarins packed in plastic l

iners were held at 20 deg to determine if freshness could be maintained during local marketing conditions. The storage life of Imperial mandarins was less than 2 weeks and that of lemons less than 4 weeks due to an increased incidence of mould wastage.
