Review on 50-Pack 8” X 12” Mylar Bags With 300Cc Oxygen Absorbers And Heat Sealable Rounded Corners - Free Long-Term Food Storage Guide Included. by Jared Gopalan

I research on mylar has been that they are not translucent. When these are held up to the light, you can see through them. The point of mylar is to keep light out, as well as oxygen. They are not very thick, which is what was advertised, so I am not surprised, but I have ordered 3.5 and 5 mil from other carriers and they were not see through. Was disappointed in these for long term use. Will have to use them for short term as I do not have confidence in them.
