Product review (3 stars): Nice but seal could be better
These bags are sturdy and hold the grease from a large roast beef cooked in my slow cooker.  The down side is the seal on the bags.  Its a simple pressure seal like those in a zip lock bag.  Personally, I'll never seal one of these bags and throw it in the trash.  I'm too affraid the seal might come loose and I'd end up with a puddle of grease under my trash bag.  To overcome this, I placed two of the bags in my freezer.  I took them out on trash day (the grease was frozen) and placed them in the trash bag.  Worked great!  I consider my grease problem solved and would rate this five stars if the bag seal were better.
