As of this posting there has been 3 suggestions for welding the plastic together with a regular clothes iron. Bonding with an adhesive of various sorts gets 6 votes.
The clothes iron is free given you have one or have access to one, otherwise you are looking at spending 10 to 100 buck depending on the size of the poly.
I will give the iron a try first. On scrap.
I went with an iron and it worked really well for bonding.
