If punctures were a concern, you could seal the inner tamper-evident, vacuum-sealed bag in a second, outer bag (with more rice and beans or perhaps colored styrofoam peanuts if you wanted). This process could be repeated as many times as you wanted, adding extra layers until the desired level of protection was achieved. Another approach would be to encase the tamper-evident packaging in wood or metal before putting it in a shipping container.
