I have some very heavy duty plastic bags I use in my business that are one quart capacity, but are a different shape than the square Zip Lock/Glad bags. They are long and skinny, rectangular, but they are one quart. Will TSA accept these? Is the mil strength of the bag going to be checked? Are the screeners going to do the mathematical calculation to prove the capacity of the bag is one quart?

What happens if my husband and I put both of our plastic baggies of little bottles in the same plastic bin for screening? How would the screener know that one was mine and one was his, not that both were mine? What happens if you have 2 baggies of little bottles?
