Using Foodsaver or similar bags or rolls, I always double seal. But I’ve started to wonder about the factory seals on those and Ziploc-type bags. How often do they fail?

Would it make any sense to use an outer reusable bag, perhaps silicone, sealed by water displacement, as routine insurance?

Why not just use the silicon bag to cook in?
