Make every bag and pouch resealable - whether the open chip bag, the opened chocolate lentils, but also the package of washing powder! simply clip it on. Already everything is hermetically sealed and has a practical lid!
In three practical sizes: for bags with small foodstuffs, e.g. sweets, peas and powders, such as coffee or ground nuts. Or for medium bags and contents that need a larger opening, like candies, breakfast cereals, pasta & co. And the wide opening fits all the rest: chips, frozen fries and even screws and other craft supplies in the garage.
