Foodsaver - poly bags

Has anyone tried to seal (not vacuum) non-foodsaver style plain poly bags/ tubes? Like what grain comes in from a brew shop. I'd like to order some but not sure what thickness the foodsaver will do without just melting them? Also any suppliers?

Thanks

I havent tried sealing non vacuum bags in my vacuum packer. I do however have an impulse sealer that I use for poly bags. I got it free from work, they were going to throw it out so I snagged it. I have seen them on ebay for between 10 and 100 dollars, they work great and once dialed in they work perfectly every time.

Thanks, Ill keep my eye on them.

My foodsaver (the black one at BB&B...I think V3460) will heatseal the poly bags that my LHBS uses for grain. The LHBS heatseals them at the store with a two-foot wide heatsealer thing (doesn't vacuum either).

I think the idea is to actually melt them though...it's melting the two sides of the bag together to seal it.

I've heatsealed a lot of non-foodsaver bags...Tostitos, potato chips, etc. The only bag that hasn't worked so far is a pretzel stick bag. It's made of really loud crinkly plastic.
