Why are pickles still put in glass jars instead of plastic jars??

they changed ketchup from glass to plastic over 20 years ago.

  • Pickles are vacuum packed. Can’t do that in a plastic jar.

  • Several manufacturing processes use live steam to pasteurize the product and/or displace the air in the pickle package. It’s possible to package in plastic, I’ve seen pickles in plastic pouches. I probably adds another step to the manufacturing process (such as irradiation to kill bacteria).

  • Perhaps because the high proportion of vinegar would degrade the plastic too quickly.
