Using vacuum sealer rolls in a minipack mvs-31 chamber sealer

Chamber Vacuum sealers can use the foodsaver type or bags and rolls.  Sometimes you need a large bag, and don't want to order a box of 500 of them.  90% of the time I use 8x12 bags, but sometimes you just need a larger bag.
Using foodsaver type rolls is the answer:')

P.S. Chamber sealers can also use foodsaver bags, but they are more expensive then vacuum pouches.
