Dynamic 10 ft. x 25 ft. 4 mil Plastic Sheeting, Clear

This sheet felt a little off. The weight of the product was fine but the gauge or thickness was light at about 13% off the stated 4 mil thickness. This is odd as the weight should coincide with thickness. The product should weight 13% less. I had a friend that works in plastics check the density and stated that density is 30% higher, meaning they are using fillers to add more weight but short-changing on true thickness of material. It's like adding a few rocks to a box to get the weight to a standard level

This wasn’t as thick as I would have liked but I should have noted that prior to purchase..
