This invention provides a porous film useful as a fresh fruit and vegetable wrapping material which is obtained by forming a large number of small recesses in an organic film and which does not allow permeation of water, bacteria, and viruses, but allows permeation of a gas, e.g., the oxygen gas or the carbon dioxide gas, and water vapor. The porous film includes the organic film and the large number of recesses formed in the organic film and having an average opening width of 0.5 µm to 300 µm and inner surfaces exhibiting affinity.
L'invention porte sur un film poreux utile en tant que matériau pour envelopper les fruits et les légumes frais. Le film poreux est obtenu en formant un grand nombre de petites rainures dans un film organique; il ne laisse pas passer l'eau, les bactéries et les virus, mais est perméable au gaz (gaz oxygène ou gaz carbonique) et à la vapeur d'eau. Le film poreux comporte le film organique et le grand nombre de petites dépressions formées dans le film organique, dont la largeur de l'ouverture mesure en moyenne entre 0,5 µm et 300 µm et dont les surfaces internes démontrent une affinité.
