I put a pool in my backyard 3 years ago and had to put a chainlink fence up because as we have cedars completely encircling the property I did not want a big solid wood fence blocking the cedars completely.
Once the fence was in we realized that the cedars were not thick enough to stop passerbys on the sidewalk from peering into the backyard so I ordered 5' x 20' or 30' foot sections of 13 oz froest green banners and used nylon ties to fasten them to the fence.
The first year I was amazed at the power of the wind and one big gust you could hear every nylon tie snap and the banner fell to the ground. I reinforced all the ties and used 2 and 3 in spots and the banner has held on for over 2.5 years with very little maintenance...... I also did not put wind slits into the banners..so they are pretty tough.
+1Frankly I doubt the Chainlink fence posts will have a chance.
480 sq ft of solid banner would make for over 10,000 lbs of force in a moderate wind.
At the very least it has to be mesh.
8ft x 60ft banner - Will be hung on a chainlink fence....
Standard 13 oz material or Mesh material?
I dont think zip ties stand a chance w/o the mesh...
Insight anyone?
For extreme situations (like yours), use STAINLESS STEEL TIE WRAPS, and you will not have to replace them like the Nylon plastic ones. They are much stronger, hold up better, and the sun does not break them down like the plastic ties.

Use mesh Zip Tie at the top and bungee balls at the bottom the bungee will allow the banner to flex a bit in the wind at the bottom as well as the mesh. I have had great luck with this method and we do a lot of large field mesh banners. But it all depends on the fence of course. Most chain link fences we attach to are the large 12' plus high fences that are seen around sports stadiums and complexes i doubt you're standard chain link will like this big of a banner much....
another mounting method.... not sure how it will work with banner material however

IMHO, ya'll are making this too complicated, get a roll or two of heavy duty steel tie wire,
you can tie through the grommets and through the mesh where needed.
Also, we always tell customers that all banners are sold as a temporary signage only,
they may last 5 years or 5 days depending on a lot of variables, the only guarantee we offer,
is it will be free of imperfections or mistakes when we install or they pick up.
