I want to add two points---
1) Vacuum bags are expensive, but you can reuse them for a limited number of times. To take the meat out, cut closely along one end, flip bag inside out, wash/dry, flip back. The bag is now ready for vacuum sealing again, just an inch shorter than it used to be.
2) We've been using Mason jars more often now for freezing solids--- berries, meat chunks, etc. There's enough air space between pieces that the jars don't crack. The glass and lid are totally impermeable to moisture loss besides the initial frosting due to the air inside the jar. Zero plastic waste.
