<P>PROBLEM TO BE SOLVED: To secure the freshness of farm products by moderately releasing a gas in a bag outside the bag and by preventing the bag from being damaged and epidermis or the like of the farm products from spilling over and scattering to the outside of the bag. <P>SOLUTION: An adjustment sheet 2 composed of polystyrene is stuck in a way that it may close a through hole 4 by forming the through hole 4 at the surface of one side of the bag 1 composed of polypropylene. An opening 3 is shut tightly by storing the farm products in the bag 1. The polystyrene has higher gas permeability than the polypropylene with respect to various kinds of gases and can release the gas in the bag 1 to the outside of the bag 1 promptly through the through hole 4 and the adjustment sheet 2. Thereby, the freshness of the farm products can be prevented from being impaired by the gas in the bag 1 and furthermore the bag 1 can be prevented from being broken with the through hole 4 as a starting point and the epidermis of the farm products from being peeled and scattered via the through hole 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
