I would like to say something about the state of "rubber" net bags in flyfishing. Seven years ago we introduced the "ghost" net bag. It was clear, didn't spook fish and flies did not get caught in it. Great! Or is it? The downside is that these net bags were made in China and all of them contained polyvinyl chloride or PVC in short.
Besides the fact that PVC is softened by adding plasticizers (otherwise it would be as hard as your household plumbing) it also releases dioxin (nasty!) in its manufacture and disposal. Manufactured in China but disposed of in the USA. And after time PVC net bags release the plasticizer and harden and yellow with age.
Unfortunately Brodin Nets has unleashed a monster and even companies such as Fishpond are using PVC bags as well as other imitators.
So with the help of companies like Orvis and LL Bean (they don't even allow PVC plumbing in their stores) we have created a mold for a new net bag that is manufactured in the USA and contains no PVC. It is our eco-clear net bag and is made from the same stuff as baby bottle nipples and will not harden or yellow. Because of the extremely high cost of producing this mold we only have one size at the moment. With enough support by you we will make other sizes.
Granted that PVC net bags are a minuscule proportion of the PVC products in the world, but I think that as flyfishermen we can make a difference in raising the awareness of this nasty plastic.
We expect other companies to follow suit and that would be a good thing. Let's get the ball rolling.
If you want to learn more about PVC and its hazards, here is a link. But there are plenty more. Google it.
Thanks for listening.
