A new generation of plastic film, who’s the permeability increases drastically with a slight rise in temperature, were used to bulk the modified atmosphere packages of mushrooms (Agaricus bisporus cv. U3 sylvan 381) in order to prevent the lack of O2 and the excessive accumulation of CO2 caused by temperature fluctuations during transportation and storage. The use of thermal plastic film allowed the level of CO2 in the modified atmosphere packages of the mushrooms (8-10%) during fluctuating period. According to the level of oxygen, this dropped from 5% to 2.6% during fluctuation from 4°C to 14°C. Final quality of mushrooms was improved by the use of a temperature sensitive film. This new film showed efficacy in preventing the accumulation of CO2 and in compensating for the drop in O2 in the modified atmosphere packages of mushrooms under temperature abuse conditions.
