I use these currently. They’re a tad thin but work fine. Also the 12oz size just fits 8 oz of whole bean with a little headspace so I’d go for 16oz bags if you want to do 12 oz of beans. Of course preground would probably fit just fine since it takes up a lot less space.

Please note you do need a heat sealer for bags like this!
