AlchemyBullies If you are intending to do patties then I would say that you are better off using the poly tubing as the bags have a gusset at the bottom that would make that a little oblong. We do sell the meat bags by the 100 if you wanted to buy some and check them out and see if they would work for you?
Another option would be the 4.8 in x 22 in Fibrous Boneless Ham Casings and stuffing, freezing and slicing them. You would get a lot more round portion out of this than I would think you would get with the meatbags? This would be fairly cost effective as well as you would get 25 of these casings with an order and each casing is 22" long so they would do a fair amount.
So, if you are going to use the full 2,000 feet then go with the poly tubing, if you don’t want to buy all of this at once then either the meat bags or the fibrous casings would be a decent option!
