#10 "Plastic Bag Fiber Kit"

#10 "Plastic Bag Fiber Kit" I want to re-use my plastic bags (or gather them up from the ocean...) and I want to do it myself. I am not sure of the off-gassing temperatures of the bags, but I'd guess there's a safer point at which bags will melt a little bit but still not burn. I imagine a loom of sorts, where you have a bunch of plastic bags in a bag and the loom pulls each bag out, welds it to the bag before it, melts it a bit, and turns it into a long thin strand of plastic. This strand would wrap around a spindle for re-use as rope, or plastic yarn-string for weaving. Could be that simply pulling it hard would generate enough friction to make it pliable and then thinned for string-making.
