I have a rather large hot wire sealing machine that I used to shrink wrap LP's (33 1/3rpm). Since I no longer use it for that purpose, I now use it to seal parts bags for shipping components. It gives a real professional appearance. I save and collect all kinds of bags now that companies ship equipment in. Some are pretty thick bags and it does do a good job sealing them. I suppose they still sell them for bag sealing. I got mine about 15 years ago for about US$350.00 Don't know what they go for now. Here's a sample of other commercial units: http://www.uline.com/Group_46.asp?pricode=wf426 Rick Russell McMahon wrote: > Summary: Looking for information on heat sealing polythene sheets together: > > > I'd welcome any comment from people who have had experience in this area. > > Russell McMahon > -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
