The US-based Association of Plastic Recyclers (APR) is seeing the emergence of plastic cans with metal ends and is worried about recyclability.
PET recyclers are already facing tough market conditions due to depressed market conditions brought on by lower virgin resin prices, which drive down recycled resin prices. “We're seeing more and more of them and we've got to put a stop to it because they are contaminating the PET stream and it's just something we can't have,” said APR executive director Steve Alexander.
“This is just a way to let folks know and draw their attention to it in a little broader fashion,” he said.
And metal ends on the PET containers are a contaminant for plastics recyclers, making their job more difficult, Alexander added.
The position from APR does not cover either the TruVue plastic can developed by Sonoco Products or the Klear Can developed by Milacron Holdings. Both of those cans are aimed at the food market and use polypropylene with metal ends.
While Alexander said his comments are not directed at one particular company, Invento Americas of Sheboygan, Wisconsin, recently started production of PET beverage containers featuring an aluminum end.
The packaging technology was created by Invento of Poland.
