Fig. 1. Effect of nested packaging on partial pressures of O2
and CO2 and concentration of ethanol vapor inside retail
packages of sweet corn during cold storage at 2°C and shelflife
at 20°C. The PVC-wrapped retail packages were stored
either in open cartons without liners, or in cartons with liners
of microperforated Xtend film (nested package). During the
shelf-life period, the liners were either left closed, or opened
and subsequently folded, or opened and rolled down the
carton. Bars indicate standard deviations of three atmosphere
samples taken from different nested packages.
Fig. 2. Effect of packaging material on partial pressures of O2
and CO2 inside retail packages of sweet corn during cold
storage at 2°C and the shelf-life period at 20°C. Each retail
package contained a cardboard tray with a pair of trimmed
corn cobs. Plastic films used for retail packaging: Xtend-microperforated
Xtend film; PVC-polyvinylchloride wrap;
SM60M-perforated polyolefin SM60M. The retail packages
were stored either within the liners of microperforated Xtend
film, or in open cartons without liners. During the shelf-life
period, the liners were opened.
