I need to do some 8' long seams on painters dust sheet. Any advice on technique and equipment welcome.
Jun 2, 2009 at 2:52 pm #1505318Cheap way – careful use of hot knife (quickly, do not linger at a spot) will work if you have a hot knife.
Spinnaker or kite double sided tape will also work but is much more expensive. Less fancy double sided tape would probably also work.
You could try a sewing machine if the plastic is not too flimsy. I tried this recently with polychro and was very pleased with result on test material
Jun 3, 2009 at 4:45 am #1505475I recall seeing a battery-powered bag sealer in my local 99p Store. It had a heated element, and you ran the bag through this element. It's quite a common technique; the element is usually a wire over what appears to be a woven glass fibre strip, with a mating strip above.
I'd look in kitchenware departments…
