I find that wide mouth quart canning jars are far better for preventing freezer burn and freezer smell than Ziplock bags.
Another thing I’ve had great success with is after wrapping something in plastic wrap, wrap foil around it and seal it well.
Both the glass and metal are better for longevity in the freezer than plastic alone.
I suffer from a lack of room. My freezer spaces aren’t large enough to easily put quart jars. I do stuff ziplocs of seeds into a couple large jars to store in my freezer though. Keeps all the fiddly bits of bags confined to one spot. I have to make do with nested ziplocs for everything else, sadly.
My goal at some point is to get a big new stand up freezer. I’d love love love one of those. Mine has ‘issues’...And I don’t really trust it with stuff that really has to be cold all the time.
