Vacuum chamber pouches from UltraSource guarantee to extend the life of your product with exceptional optical quality (clarity, high gloss) and a consistent seal every time. Stronger, thicker seals eliminate product loss, freezer burn, and dehydration while providing extra protection during transport and handling. High-clarity transparent Poly/nylon material makes product easily identifiable through the seal. Compatible with small and large vacuum chamber machines. NOT INTENDED FOR FOOD SAVER SEALERS.
The thickness on these bags were stated as being 3 mils, but the Vacmaster bags in my pantry are also 3 mils and are much thicker feeling. What's up with that? A simple glance on the side of the box reveals these bags are made in China! The listing on Amazon made no mention of this! The genuine Vacmaster bags are made in USA. So now I'm stuck with 1000 inferior quality chamber seal bags. Do yourself a favor and spend a little extra money to get the Vacmaster bags and avoid the "made in China" imposters.
