Good bags
I seal air filter media with these vacuum bags. Some of it consists of small, sharp rocks. They were puncturing thinner bags. This thicker material seems to do the job much better.
Built to last, the VacMaster® 4-Mil Vacuum Packaging Chamber Pouches are designed for high puncture and abrasion resistance, giving an added layer of protection. Upgrade to the 4-Mil Chamber Pouches, and worry no more about bones poking through bags or tears and leaks ruining the seal. Great at handling spiny, sharp, or boney items, the 4-mil material is thick enough to prevent tearing or leaks. Protect food from freezer burn and dehydration with our high barrier Nylon/Polyethylene construction that provides optimum freshness and a positive reliable seal, keeping food fresh up to 5x longer. BPA-free and FDA approved pouches are true to dimension and can be frozen, refrigerated, microwaved, boiled, or cooked sous vide. VacMaster® pouches are transparent, allowing for easy identification of the product.

Opted for heavier 4 mil bags. Used 3 mil bags in past and have loved them but they occasionally got hole in them from accidentally dropping on floor after item is frozen. Haven't dropped any of these but they are definitely heavier. Will be ordering these in future.
