I've gone thru two cheap "Heavy Duty" freezer/sealer bags now for the FoodSaver, trying to bag up some dried rice. They seem alright initially, but the seal is obviously failed the next day, due to small pinholes created by the rice, when sealing. Anyone ever bag rice with these and know of a decently priced bag that will get me there? Or should I just be sealing them without vacuum packing them? I'm lost.
