Vacuum sealed meat does indeed keep much longer refrigerated. "Fresh" NZ lamb is sold with 6-8 week (?) expiry dates at Costco. There are two layers of plastic and it is heavier than with consumer grade sealers. Freezer zip bags are arguably as good as the latter and may be vacuumed by inhaling through a straw or even directly with clean lips. Easy peasy lemon squeezy, sans claptrap.
