Vacuum bag thickness is measured in mils or THOUSANDTHS of an inch. the bags I use are 5 mil or .005 inch thick

The fact that you say you weigh everything in your pack and "discovered" that thick plastic boxes are lighter than exponentially thinner bags just shows that not only have you never weighed anything in your life, but that you also probably don't even HAVE a pack and also lack the basic understanding of a 9 year old.
Admit it, the sum total of your outdoor experience consists of walking through the sporting goods section of K-Mart and watching 2 seasons of Bear Grylls.
