Is it totally safe to use 100 percent PCR plastics for packaging food or drink products?

It's really great to recycle plastic, since it has significant environmental (and economic) benefits, but it won't do if it won't be safe for the consumers, right?

And, lastly, I hope you would work out in sharing this technology to others, since many still don't know that plastics can be, and should be, recycled. Thanks.
