Potato chips are a favorite snack food Earth side. It seems that currently they are not allowed in the ISS (anything with significant crumbs -- such as potato chips ... can't go.) and that chips bags will expand as the surrounding pressure decreases (you notice that your bag of potato chips seems to be about to explode). We also know that if a package is designed to hold moderate pressure it will not explode for the same reason the Space Shuttle tires don't explode. At the same time a bag of potato chips needs to be sealed so it can be opened by hand.
At some point there is going to be more than one place in space, and there will need to be shuttles moving all those chips around Google images 'potato chip delivery truck' Most of us are familiar with the trucks delivering chips, essentially they are big boxes that keep the chips contained, the driver stops at a store grabs some chips and takes them in.
What I am really wondering is if the potato chip delivery space truck will be pressurized. Does the driver need to dock at a truck sized air lock, or is he wearing a space suit and takes the chips in through a man sized air lock? He might be making deliveries on the Moon or micro gravity, but in any case where there is enough traffic he is probably going to be making deliveries like his Earth bound counter part, the goods go in the front door of the building.
Note: In this question, I am assuming multiple populated habitats without interconnecting pressure areas.
