Document Type and Number:
WIPO Patent Application WO/2020/080542
Kind Code:
A1
Abstract:
Provided is a freshness-retaining film capable of efficiently decomposing ethylene generated from foods (in particular, fresh foods, vegetables, fruits, and the like) and plants other than food plants into water and carbon dioxide molecules not only under light conditions but also in darkness. This freshness retaining film is provided with a first layer 1, a second layer 2, and a third layer 3. The second layer 2 is located between the first layer 1 and the third layer 3. The first layer 1 contains zinc oxide in a resin which tends not to transmit oxygen and water vapor, and the zinc oxide has a photocatalytic active site coated with a coating agent. The coverage of the zinc oxide with the coating agent is 0.3 to 1.2%. The second layer 2 contains an organic fungicide in a resin which tends not to transmit oxygen and water vapor. The third layer 3 is made of a resin which tends not to transmit oxygen and water vapor.
