Magnomer coatings prequalified by How2Recycle

Framingham, Massachusetts-based startup Magnomer, which specializes in magnetizable coatings for packaging in order to improve separation in existing recycling systems, has announced that its Magmark SS coatings for polyethylene terephthalate glycol (PETG) shrink sleeves have been prequalified by How2Recycle for use with an eligible bottle, sleeve and cap.

The coatings previously received Association of Plastics Recyclers (APR) recognition in 2023.

How2Recycle, a project of the Charlottesville, Virginia-based environmental nonprofit GreenBlue, is a standardized labeling system intended to communicate disposal instructions to the public. Brands seeking to use the How2Recycle labeling system must first become members.

“Because standard PETG shrink sleeves on PET bottles are considered detrimental to recycling, How2Recycle may designate a PET bottle with a PETG sleeve ‘Not Yet Recyclable,’ or instruct consumers to remove the sleeve prior to recycling if the sleeve has a full-length perforation," says Marina Solis, research and development (R&D) project manager at Call2Recycle.

Magmark SS coatings, together with a PETG shrink sleeve and an otherwise recyclable PET bottle and cap, allow the bottle to be considered “Optimally Recyclable,” without the removal of the sleeve, according to Magnomer.

"We believe that this is the first time that a PETG shrink sleeve technology has been prequalified in this way, and it is Magmark SS that makes the difference," Magnomer President and CEO Ravish Majithia says.
