LDPE is very easy to obtain ...... your just looking in the wrong place.
Try a plastics manufacturer, eg "Poly Products" in Adelaide where I
am. Pick you thickness. Buy by the roll. OK, a roll is a little
expensive ($80 for 2m wide by 50m length) but you will make quite a few
caps from this.
Use building grade at your own risk ....... high % recycled and a bit of a
lottery. you might be OK, but all that labour and 5 minutes to death is a
poor plan. Go high grade from the start.
PS: Good to see a few more Oz coilers coming out of the woodwork ;-)
