You can thank the U.S. Army's Natick labs, for the invention of retort pouch technology.
Developed as a way to create a lighter method of conserving food, as an alternative to the traditional steel or aluminum can, the "flexible can" pouch was developed so as to not only lighten the load a soldier needed to carry their rations into combat, but to also prevent the enemy from using the waste produced from the previous MCI rations (c-rats) against the soldier, i.e. the cans (perfect for grenade booby traps)
The long shelf life was an added bonus, stemming from the high pressure pasteurization process.
