Short answer---- cut bags into strips and braid them.

loh_kah_hoe,
When you cut plastic bags in narrow strips you can use those to make string like all other string.
If you are patient you cut one long spiral out of each bag, if you do not like cutting that much you can roll the bags so that with each cut you have a circle of plastic. Cut those and use them to spin or braid.
More info on spining (plastic bags) you can find in these 2 threads:

For anyone who's interested and likes to make plastic bag slings, I've developed a method of melting strips of plastic together for braiding. (I 'spose you could just tie them, but when I do this I get bits sticking out of the braid.) All that's needed is some card, some normal aluminium foil used in cooking and a desk lamp with flat glass in front of the bulb.  
 
1: Get a strip of card, long and about 5cm wide. Cut a flap the width of the plastic strips you want to melt together into one end of the card (green lines). Leave a narrow gap and cut the rest of the card to the width of the lift-up flap.
 
2: Cut a piece of foil to a bit wider than the plastic strips. Wrap this around the end of the card, below the lift-up piece.
 
3: Put the ends of each strip of plastic below the lift-up bit of card, resting on the foil and coming in from either side. They should overlap by however much you want to melt together.  
 
4: Fold the long left part of the card over the foil, plastic and card, back and forth. (brown-red lines)
 
5: Turn the lamp on, wait for the glass to heat up, and press the foil underside of the thingo against the glass. Your fingers should be on the other side, pressing all the layers of card together. The strips of plsatic dangle downwards.
 
6: Wait ten or so seconds then take the whole lot down. The plastic should be fused together well enough to braid it as a single piece. If your fingers get hot, the plastic has probably melted by then.
 
WARNINGS (and stuff): Obviously, the lamp is hot. Don't burn yourself. It's probably best to work near an open window and keep your face away from the melting plastic. I'm not sure if it gives off fumes. Their's also a possibility the paper will catch fire, but I think it's unlikely.
Just be careful if you try it.    

Sorry about that.

Basically it is a long piece of card with a flap at one end behind which the ends of the plastic strips rest on a piece of aluminium foil which heats up and melts the plastic together. The ret of the card is folded over it back and forth for insulation against the heat, and that's where you hold it.

? about the sling after fused together is it stonger or weaker than if just braided

If the fusing is done exactly right the fuse braid would be a tiny bit stronger, but if the melting is a little overdone the braid would not be stronger, it would be weaker instead.
When the overlap is long enough to overcome the stretch of the braid, say 2,5 cm (one inch) on a tight braid to 5 cm (two inch) on a rather loose braid, there is no loss of strength for the connections.
