My food saver has always worked for the older packaging. I not not in the basement right now, the gold bags reseal fine.
My LHBS has been stocking a new hop supplier's line that comes in stiffer white bags that my food saver cannot seal. Based on that, oh so detailed description, will a hair straightener work on these new bags.
I may need to raid my 3 daughter's rooms. One of then has to have one.
