A strategic partnership between Sulayr, BASF, OEM Bobst and Evertis has led to the development of a recycling process for multi-layer PET with water-based adhesives that allows the PET to be separated and reused as part of a closed-loop system by the companies involved.
The process involves a multi-layer film produced by Evertis comprised of PET and PE layers, which is laminated with BASF’s Epotal water-based adhesive and processed with a Bobst coater. Sulayr says that it separates the multi-layers and makes the PET available for re-use, with the recycled PET delivered to Evertis and other film producers to restart the film production cycle.
The process is reportedly applicable to both post-consumer and post-industrial multi-layer waste. According to the company, the speed and cost-effectiveness of the process depend on the debonding of the films.
Miguel Ángel Arena, CEO of Sulayr, explains: “Our technologies enable us to delaminate most types of PET-containing multilayers and bring the recycled PET back to the industry.
