Estimating the term…
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.
A storage and transportation method for agricultural products comprising the steps of:
A package for agricultural products comprising a container with a particular shape formed from a gas barrier plastic material, in which an agricultural product is tightly sealed, together with an excess of an inert gas, with the amount of said inert gas adsorbed by said agricultural product taken into consideration, in such a manner that said particular shape of said container is not substantially changed due to the decrease of the inner pressure of said container caused by the adsorption of said inert gas by said agricultural products, wherein said plastic material is a high nitrile resin comprising a copolymer of (i) an unsaturated nitrile component in an amount of 50 wt.% or more, and (ii) a monomer component which is capable of being copolymerized with said unsaturated nitrile component.
A package comprising a sealed container with the wall thereof made of a gas-barrier plastic material, having shape-retention characteristics, a smaller part of said wall made of a film portion which is thinner than the remaining larger portion of said wall, containing therein an agricultural product, together with an inert gas, said film portion being capable of being drawn towards the inside of said container when the inner pressure of said container is decreased as the said inert gas is adsorbed by said agricultural product, thereby preventing the overall external shape of said container from being distorted, and wherein said plastic material is a high nitrile resin comprising a copolymer of (i) an unsaturated nitrile component in an amount of 50 wt.% or more, and (ii) a monomer component which is capable of being copolymerized with said unsaturated nitrile component.
A storage and transportation method for agricultural products comprising the steps of:
