Label and packaging materials supplier Avery Dennison Corporation has announced that it has won the Society of Plastic Engineers (SPE) 2013 Environmental Award in the Design for Sustainability category for its Bottle-to-Bottle Portfolio of labeling materials, which dramatically improves the recycling of polyethylene terephthalate (PET).

The Environmental Stewardship Awards, hosted by SPE, recognize corporations and other institutions that have demonstrated environmental leadership and excellence. The ceremony was held in New Orleans, LA, on March 21 at the Global Plastics Environmental Conference.

“We are excited that our Bottle-to-Bottle label has been honored by the SPE Environmental Stewardship Awards,” says Donald Nolan, president of Avery Dennison Materials Group. “As a manufacturer of pressure sensitive label materials, we are always looking for ways to make our products more sustainable. With the ever-increasing popularity of pressure sensitive labels, it’s critical that we make it easier to remove these materials from PET containers during the recycling process, and we are proud to be leading that charge.”

According to Avery Dennison, the Bottle-to-Bottle portfolio leverages unique technology to meet an industry need to increase the recyclability of PET containers. Direct printing, paper labels and standard pressure sensitive labels applied to PET bottles tend to lower the recycling efficiency and the quality of recycled PET. In 2010, 1.5 billion pounds of PET were collected for recycling in the United States, yet reclaimers reported yield losses ranging from 24.4 percent to 32.2 percent due to contamination by labels, adhesives and other components – amounting to a loss of over 40 million pounds of bottles.

The Bottle-to-Bottle Portfolio for PET Recyclability was designed to help brands adhere to Association of Post-consumer Plastic Recyclers’ (APR) Design for Recyclability Guidelines for Plastic Bottle Recycling so that their PET bottles can be easily collected and do not contribute to contamination of the PET supply.

The Bottle-to-Bottle portfolio is anchored by SR3010, a proprietary “switchable” adhesive that adheres to PET containers until its cohesive bond is broken by the caustic solution used in the recycling process. Thus, the label material releases from PET bottles during recycling process with no adhesive residue.
