ABSTRACT:
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 .mu.m to 300 .mu.m and inner surfaces exhibiting affinity.
