. Place the bag in a paperback book so that you have a nice seal. If what you have in the bag is too bulky to fit in a book, use two pieces of lath or similar to "pinch" the end of the bag. Burn the excess off with a Bic lighter. This will melt a seam along the edge of the book/lath. With very little practice, you can get a dust-proof seal.

I've tried it...good seal but can be done only with solids or powder fills.Moreover the seal itself sometimes turns blakish due to soot formation.With liquid as filling it becomes messy to carry out this method of sealing.Thanks NachoMahma

I agree with purduecer and iron could work well, or any hot piece of metal. You would be advised to place something under and on top of the bag to which it will not stick - I'm a bit short of easy ideas, but some kind of foil or paper perhaps. Getting the temperature right will be the tricky part I should think.

Thanks.....Got a good instructable and here it is........1.Place the polythelene sheet on top a flat wood or clipboard or some plate which is heat resistant.2.Place a ruler on top of the sheet.3.Run a heated soldering iron along the edge of the ruler on the polythelene sheet.This should neatly seal and cut the seal both at the same time.The job is done.

Yes that's a good one - only drawbac is that you get plastic on the soldering iron. Publish it (here)! L

I attempted the soldering iron method just today and believe me it wrks just fine.But must say ...this is good only for bags with heavy density....the thinner ones just melts and does not seal well too.

It may be possible to run an iron over the seal...

This will not work.....the polythelene sticks all over the iron and messes up.Thanks anyway
