After assembling a greenhouse frame from PVC and expecting the plastic covering to be no ploblem using tape to secure it I've found tape wont stick to the plastic(clear plastic tape, 3M plastic tape & duct tape).
Can someone give me some ideas of what will help secure the plastic sheet to the frame?

Try cutting some of the PVC into maybe 1" lengths and then cutting the length down the middle. Wrap the plastic around the frame and then force the "clip" over both the plastic and the frame - I don't think you'll find a tighter joining system although you may need to go one diameter larger for the clip pieces depending on how accurately machined the originals are.
You might even be able to use poly-pipe (irrigation tubing) to make the "clips" if you have some of an appropriate size "laying around".
On the outside of the base bolt the frame to a baseboard. Then add wiggle wire and there is no need to tape anything. It's the best thing I've ever used.

You may need special clips to fit around the pvc pipe. I have used bulldog clips to hold windbreak (or plastic) to round pipes but they do go rusty. They work OK Someone else used split pipes, eg: C +[ O , to go over the top of the pipes and plastic, I haven't tried that. I'd imagine the clip would have to be quite springy, tight enough to require force to remove, but not sharp enough to cut the plastic (altho tape applied under make spread the load). At the moment I'm using No. 8 wire hoops with plastic held on by plastic clothes pegs. Anything to avoid paying a fortune for specialised clips...
Nothing sticks to plastic that's in the open elements. If I was flush with money I'd consider a double row of wire hoops, with the plastic held between. I mean you could even consider rope tied over the top if wind is a problem. When it comes to high winds I would even fling a huge sunscreen cloth I'd been given, over the whole shebang to cut down the wind. It worked fine too.
Perhaps a look at commercial setups of similar greenhouses will give you ideas for fasteners.

Don't you find that the plastic tears? How about using those plastic packing strips as well as a kind of load distributer under the staple itself? How does pvc handle being stapled?

Well, that was (nearly) the ultimate test of the "clips" :) - if the plastic ripped rather than coming off of the frame then you've definitely done something right!
I can't think of anything different to chicken wire to fix the ripping problem though :(
