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 Dube Jansen

I have purchased 4 different brands of Mylar bags in the pastand this is the only one that I have serious concerns about the thickness. The seller claims that thickness isn’t an indicator of its ability to prevent oxygen from getting in and I was intrigued by this claim. Now that I’ve had a chance to assess for myself, I’m rejecting this claim as just a way to sell a product using cheaper materials. This, of course, is only my opinion. My evidence is this: I filled one of these bags with freeze dried pulled pork. There are absolutely no bones or bone fragments in the meat. However, the meat is crisp and brittle enough to create small pinhead size dimples in this thin material which to me looks almost like there could be a pinhole. My other Mylar bags do not do this, and I don’t feel like I want to take a risk only to discover 10 years down the road that my suspicions were confirmed. The seller claims it can withstand pressures equivalent to 2.5 cinder blocks per square inch but that does not mean it can withstand punctures, even with blunt and fragile materials. No thanks. I’m not risking it so I will return them.
