Zusammenfassung:	PURPOSE:To remarkably prolong freshness-keeping period, prevent the lowering of commercial value caused by clouding and maintain the freshness of vegetables and fruits, by using a laminated film having specific steam, oxygen and carbon dioxide gas permeabilities and having antifogging characteristics. CONSTITUTION:Freshness of vegetables or fruits can be maintained by packaging the vegetables, etc., with a laminated film having a moisture-premeability of 15-200g/m .24hr.40 deg.C, an oxygen permeability of 3,000-35,000cc/m .24 hr.atm.20 deg.C.90%RH and a carbon dioxide gas permeability of 12,000-130,000cc/ m .24hr.atm.20 deg.C.90%RH, containing an antifogging agent on at least one surface layer exhibiting weld sealability, facing said surface layer inward. Preferably, the film exhibits a weld seal strength of >=3.0kg.cm/15mm when weld sealed at 270 deg.C and at least one surface of the film exhibits antifogging property within a period repeating the temperature change between 20 deg.C and 40 deg.C.
