Why is there so much air in a bag of crisps ?

    Question.

    Adds to the volume, shelving and shipping cost. Do they need air for longevity - if anything I would have guessed the less air the longer the shelf life.

    So why are Tayto et al giving us bags of air ?

    Cushioning to protect the crisps during transport.

    It's to justify the otherwise unnecessary super-trucks that are too tall for the port tunnel, even if though they can't use the M50 toll bridge when it's windy. :rolleyes:

    "some settling of contents may have occurred during transport"


    Crisp bags can be filled with nitrogen. You can get machines with molecular sieves that remove the oxygen from air.


    Super glue must have oxygen !
    So always leave an air void when closing it or it will go hard.

    I thought it was supposed to be a preservation thing. Nitrogen would be inert and prevent rotting wouldn't it?

    yeah it would stop oxidation, ie. fats going rancid
    and it would stop oxygen breathing organisms (though some bacteria / fungi don't need oxygen)
