I got some Heat Sealable 70 Denier Oxford Nylon Fabric from Rockywoods just to mess around. I am wanting to make a liner for my pack with the stuff but I am really struggling trying to get it to seal up. I have a pretty good iron and have jacked it all the way up but the seem just don't see to want to hold vary well. I used a granite chess board as the base and a metal T-square to get an even seam and give the iron a guide to run down.
One thing I found out in my frustration is that my food vacuum sealer does an awesom job But I can't do a lont with a 7" long dry bag that has to be rolled at least three times.
Any pointers from anyone?
