Which bag size would be best for 2 chicken breasts?

First, I purchase my vac bags from 'Lemon Tree Foods' www.VacandPac.com. The bags are sturdy and a quality product. I have an assortment of sizes that fills my needs. I have roll - width 11 inches. I have a roll - width 8 inches. I have pre-cut bags sized 12 inches by 8 inches. And finally, I have pre-cut bags sized 12 inches by 6 inches. I use the pre-cut 12 by 8 the most. This is a good size for double count chicken breasts. Use 12 by 6 for single count chicken breast. I find the roll's necessary for vac'ing food in cook ware ready for oven. When using roll cut-your-own size bags be sure to double seal each end. I make two meat loafs at-a-time: cook one and vac the other in its pan using the large width roll. Mac and cheese: make two - cook one - vac the other using a meat loaf pan. I vac foods that I'm not going to freeze just to give the food longer shelf life in the frig. Give those left-overs (think stews) an extra 5 days freshness. YOU CAN VAC JARS FOR THE SOUPS! BTW, I'm still using my KitchenBoss Vac machine with no problems.
