That’s just not true. I make flexible packaging and we use thousands of pounds of post industrial resin (made from scrap material produced in house) and post consumer resin (made from used packaging.) They’re all coextruded; frequently made up of 10+ different types of polyethylenes, polyamides, and ethylene-vinyl alcohol.
I don’t think “not true” is fair- I have a soure if you’d like to hear it from someone more authorative than some random internet person (unfortunately I think it might be behind a paywall)[0]
Either way, that’s cool! I’m surprised you can build flexible packaging from that, but I’d be really, really surprised if you can use something that crude to fit the other niches of plastic like building technology, clothing, etc.
