ABSTRACT:
A hermetically sealed package wherein the inside of a container having shape retentive capability is formed from a gas barrier plastic material into which an agricultural product such as rice is filled and sealed together with an inert gas provides an efficient storage and transportation system. Once the product is sealed in this package, it is handled in an integral manner from the packaging area to storage through the distribution channels to the final consumption site. A container formed from a high nitrile resin is suitable for applying the system. Shape retention characteristics is achieved by using a container formed from a gas barrier plastic material packed with an excess of an inert gas, with the amount of the inert gas adsorbed by the agricultural product taken into consideration, or by using a container made of a gas-barrier plastic material, with a smaller part of the wall being made of a film portion which is thinner than the remaining larger portion of the wall.
