I have tried using a foodsaver with regular bags, but without any success. I dont think it could be possible anyways. Foodsaver bags are textured, and this texturing permits the air to flow in the bag during the vaccum proccess. If you try to suck the air out of a regular bag, the air cannot flow once the walls of the bags come in contact with eachother, especialy if some kind of light pressure is applied (sealing bar of the foodsaver). The texture in the foodsaver bags creates microchannels (ok maybe not so micro but evryone abuses micro and nano these days) that will prevent the creation of an airtight seal, even if moderate pressure is applied on the bag. These channels disapered when the bag is heat sealed. So unless you find the way of getting the air to flow in regular bags (which I doubt is feasable) you wont be able to use them in a foodsaver. Edit : You could actually seal other kind of bags (i did this) but you would not be able to VACUUM seal them.
