So every time we get bread it comes in a stretchy bag. However, once we pull it out of the freezer later the bag is noticeably more crinkly and brittle. Anyone know why this is? I can’t seem to find an answer to this phenomenon anywhere.

    I’d say this is probably thermal cycling. Some polymers can degrade with repeated thermal cycling (ie tires ‘cycling out’). Google scholar has a few papers on it.
