Original post edited to add:
I should add that the reason I want to keep the original packaging is that the text describing package contents is legible. I write a lot of stuff on the outside of the s.v. bag in a fat black marker (including the date purchased, weight, the temp/time/date cooked). After vacuum sealing, the bag is usually badly wrinkled, so almost illegible. And I don't want to defrost it just to read it.
