Can you use any size vacuum sealer bags?

Some vacuum sealers may have a max size of sealer bag they are able to seal.

However, you should usually be able to seal any size of bag which is smaller than the max size your machine is able to handle. If you’re not certain, double-check with your sealer’s specifications before you try. Otherwise, you could end up overheating your sealer, which can shorten its lifespan.
