We don't use a vacuum sealer, but we do heat seal Kapak bags with tissue in formalin, and store them for 15 years with no leaks. I've retrieved samples that were 14 years old, and they were as good as the day they went in the bag. I am not sure the vacuum would work without sucking out the formalin. Kapak bags can be ordered through various vendors in a multitude of sizes, and the heat sealers are not too expensive. Jackie O'
