StePac L.A. Ltd. has developed customized, proprietary, polyamide-based packaging technology for ensuring long-lasting freshness in bulk deliveries of blueberries to distant destinations. The new multi-layered packaging, which is the outcome of several years R&D ensures this high value fruit arrives in wholesome condition, with its natural protective bloom intact.
StePac's breathable, multilayered polyamide-based Xtend packaging is designed to not only regulate headspace gas composition, but also relative humidity. This significantly reduces the risk of condensation build-up and ensures that any condensation that might form within the packaging diffuses out. “The preservation of natural bloom is a far more important parameter than slightly lower weight loss,” notes Ward. “It is the outward indicator of freshness and translates into higher prices for blueberries in the Chinese market.” Sources from within the industry disclosed that at the time of the visit, Peruvian fruit with high bloom arriving in Xtend packaging were typically sold for prices reaching RMB160-200 per carton of 12 clamshells, in comparison to RMB100-120 per carton of 12 clamshells for fruit with less bloom arriving in polyethylene packaging. StePac uses a wide range of polymers with varying WVTR values, including polyethylene, for the delivery of fresh produce in different packaging formats. “Custom-designed packaging that provides optimal modified atmosphere and moisture control and ensures that the produce arrives in prime condition requires a thorough understanding of the interaction between the physiology and pathology of fresh produce and its packaging environment,” adds Ward. “. Polyethylene-based packaging solutions are suitable for certain produce items and applications, but are an inferior solution for bulk shipment of blueberries.” Come to meet us and to our products at the upcoming Fruit Logistica 2019 in Berlin, February 6-8, Hall 26, Booth F-12. |
