Welding plastic bags

Step 4 Done!

When you have finished the seam, inspect it and test it by tearing it apart.
After some practising you will know the right speed and presure for different materials.

Use your new skill for making kites or inflatable stuff or something!

Just now finished an attempt at making some tubing, and its a good first try! I only used a cut section of one bag wrapped around a paper stick with a layer of parchment inbetween the plastic. So far, its like a fragile drinking straw with a bunch of small holes in it.

next time, im making it thicker and not applying as much heat. In this case for flexible tubing, possibly, too much heat will make it too stiff and hard.

Hey Aleksi, thanks for this. I was able to teach an inflatables Class in Haiti where every student got their own soldering iron + sandpaper kit, it worked like a charm.

i'm also an artist, this is a useful brainstorm page. you might also be interested in learning about the invention of the standard balloon for your own invention process.

i am wondering if a wood burning tool will work as well as the iron mentioned above. if it melts plastic...i don't see why not.

Hi this technique sounds perfect for what i am trying to create! for my degree show i was wanting to use inflatable black birds. Do you think i could achieve the bird shape using this method? how to fill the shapes with helium do you need to add some sort of device to the balloon? cheers Dawn x
