<p>PURPOSE:To prevent water-rot of green vegetable having vigorous physiological activity and to keep the green vegetable in highly fresh state over a long period, by packaging the green vegetable in a packaging bag made of a specific multi- layered film. CONSTITUTION:The film-layered film used in the present process has water- vapor permeability, oxygen permeability and carbon dioxide gas permeability adjusted within respective specific ranges, is provided with an antifogging agent on at least one of the surfaces to enable continuous antifogging effect in the course of repeating the temperature change between 0 deg.C and 40 deg.C and gives a fusing seal strength of >=3.0kg-cm/15mm when subjecting the surface layer to fusing seal at 270 deg.C. The film is formed in the form of a bag having at least 3 closed sides facing the surface layer inward. One or more notched holes having a notch length of 4-100mm are applied to the bottom edge of the bag leaving >=50% of said bottom length in sealed state. Green vegetable having vigorous physiological activity is put into the above packaging bag.</p> |
