In trials on bulk packs, 28 sweetcorn (cv. Super Sweet) ears were packed in StePac L.A. Xtend bags (types 100, 120 and 130), placed in cartons, and stored for 25 days at 1 deg C. Control ears were placed in cartons covered with ice. In trials on consumer packs, the highest quality ears from the first trial were packed (2/pack) in Xtend 100, 120 or 130 bags or in polyethylene (PE) or Cryovac PD 941 bags, and held for 7 days at 5 deg to simulate shelf life conditions. Excessive humidity promoted decay in the iced controls, the Xtend 120 bulk packs, and in the PE, and to a lesser extent the Cryovac, consumer packs. The Xtend 100 and 130 films were the most suitable for bulk packing. The lower RH in the consumer packages of Xtend 100 and 130 caused some denting of the kernels, and the Xtend 120 film, although less suitable for bulk packs, maintained fresh quality in the consumer packs.
