Re:Use of a Check Valve for sealing

[Ron Pratt]

how do you intend to seal the hole in the bag to make it airtight so that it can be left in? My experience is once you have a good seal and tight contact between the Drybag and the meat surface the bag bonds with the meat in just a material of days so no additional vacuuming is needed. By the time the aging is over and you are peeling off the bag I find it is similar to peeling the back off contact paper.
