The test was performed at 40 °C for 10 days in 95% (v/v) ethanol,
and at 20 °C for 2 days in isooctane to simulate roomtemperature
storage (more stricter storage conditions than in reality). Exposure was
by total immersion (both sides in contact), although in practice only one
side of the filmwill be in contact with food. Samples of film were cut to
produce specimens of 1 dm2 and immersed in a glass tube with 100 ml
of food simulants.
