Abstract

A system and method for long-term storage of a commodity in a weight range of 10-2000 kilograms includes hermetic sealing of an ultra-low permeability, easily transportable, flexible long-term storage container. The long-term storage container may also be treated using non-toxic insect repellents of botanical origin or using a synthetic pyrethroid. The long-term storage container includes a triple layer co-extruded film having an outer layer, an inner layer, and a middle layer. The middle layer is comprised of ultra-low permeability material or materials. After hermetic sealing, the long-term storage container having the commodity therein is placed into an outer container for protection during transport.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS

[0001] The present application claims priority from Provisional U.S. Patent Application Ser. No. 60 / 658,586 filed on Mar. 7, 2005 and titled “Flexible Transport Bags,” the entire subject matter and contents of which are incorporated by reference herein in its entirety.FIELD OF THE INVENTION

[0002] The present invention is directed to a system and method of hermetic storage and easy transport of commodities. More specifically, the present invention is directed to providing an insect- and mold-resistant method for use in storage and transportation of bagged dry commodities using a hermetic, portable container. The purpose of the present invention is to combine easy transport with safe storage for dry commodities such as seeds, pulses, oil seeds, nuts, and grains normally transported either in unprotected man-portable grain or seed bags or by mechanized handling using “Big Bags.” The present invention provides a storage system having low permeab...

Embodiment Construction

[0026] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be understood by those of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and structures may not have been described in detail so as not to obscure the present invention.

[0027] The present invention relates to flexible reusable portable storage containers which have very low permeability to air, CO2 and water vapor as described below, and which can be used for both short or long term storage and subsequent transportation of dry commodities. Such containers are referred to hereinbelow as “long-term storage containers” since they are capable of storing commodities for at least four months. However, it should be readily apparent that the “long-term storage containers” are not limited to long-term storage, an...
