A bulk material container is disclosed which includes an exterior body and an interior body having separation means associated with the exterior and interior bodies to provide protection from punctures and to provide for expansion of the products packaged within the interior body. The interior body comprises a first inner liner and a second outer liner laminated together in a predetermined manner to provide a stress reduction means in the interior body. The stress reduction means is formed by offsetting the inner and outer liner manufacturing joints from each other a predetermined distance to provide a triple thickness at the two manufacturing joints along a portion of one of the upstanding walls of the interior body. A topcap with water proofed corners and a retention area for a banding strap may be used with the container and when used the topcap also has means for being interlocked to the exterior body of the bulk material container.
