Document Summary

Cereal companies switch from box to bags to reduce cost/waste and help the environment. Basic function of packaging: convenience, containment, communication, protection. ** how is the switch in the packaging how does the affect the product. Oxygen will eventually seep into the package. Communication: if you are new to the product you may pick the box over the bah, a regular customer wouldn"t mind since they are familiar with the product. Convenience: bag cannot stand straight, not stackable. Molded paper (made on 3d mold instead of sheet) Aseptic packaging food and packing are both sterilized and put together in a sterile environment to have an aseptic product. Not common for liquid product: ie: beans in tetra pack packaging but recart line. Packaging is made to be able to with stand heat (go through retort steps) Retort- food and packaging are combined without sterilization and then thermal processing is applied.
