Curious what brand of vacum bag rolls yall are using? I've noticed with my vacmaster bags im loosing my top seal a decent amount where the bag is folding some when I have meat in it and perhaps I'm getting a slight crease in bag? Or they could be just less tough in the freezer but seal is breaking after freezing within a couple weeks. I have a vacmaster sealer.....not a chamber and its a decent machine. Just curious if there was any brands of vac bags yall thought were tough or outperformed another brand......seems I had less problems with a seal using food saver brand bags.
