A container is described, which may be used as part of item sortation within a facility, as well as item deliveries to end locations. In an example, the container may be configured to transition between a collapsed state and an expanded state. The container may include a loading panel and an unloading panel. The loading panel may include a fastener such that an opening can be selectively created and closed in the expanded state. Accordingly, packaged items may be inserted and securely retained in the container through the loading panel. The unloading panel may also include a fastener such that an opening can be selectively created and closed in the expanded state. Accordingly, the packaged items may be unloaded from the container through this opening. The container may also be dimensioned to facilitate stowage of the container in the collapsed state and loading/unloading of packaged items in the expanded state.
