Flexible packaging’s role in a sustainable world

April 30, 2018

 

 

The Flexible Packaging Association introduces a free 180+-page report that provides a holistic view of the current sustainability benefits of flexible packaging as well as future opportunities.

 

A new report from the Flexible Packaging Association, A Holistic View of the Role of Flexible Packaging in a Sustainable World, provides a holistic view on the sustainability benefits that flexible packaging offers, provides foresight into future sustainability implications for flexible packaging, and develops six LCA case studies comparing flexible packaging to other packaging formats across a range of products.

 

The report, prepared for FPA by PTIS, focuses on the segment of the industry that adds significant value to flexible materials, usually by performing multiple processes such as printing, laminating multiple layers, and adding coatings, all of which aid in performance of the material, improve the consumer/user experience, and/or extend the shelf life of the product. It focuses on the U.S. perspective, though global data and context are utilized to provide a broader picture, and looks at the current state for flexible packaging, while also providing foresight into potential future implications.

For the report, six different Life Cycle Assessment case studies were developed using the EcoImpact-COMPASS® LCA software, which allows for quick life-cycle comparisons between different package formats. The case studies include packaging for baby food, cat litter, ground coffee, laundry detergent pods, motor oil, and single-serve juice-flavored beverages. The results from the case studies show that flexible packaging has more preferable environmental attributes for carbon impact, fossil fuel usage, water usage, and product-to-package ratio, as well as material to landfill, when compared to other package formats.

 

The report also shows that flexible packaging offers a number of sustainability benefits throughout the entire life cycle of the package when compared to other package formats, including material/resource efficiency; lightweight/source reduction; transportation benefits due to inbound format and lightweight nature; shelf-life extension; reduced materials to landfill; high product-to-package ratio; and beneficial life-cycle metrics.

Despite the number of sustainability benefits, there are challenges facing the flexible packaging industry. The main challenges are post-consumer packaging material collection and recycling. There is currently a lack of recycling options for multi-material laminated films, such as snack bags and foil pouches, which are difficult to separate into their various material substrates.

 

The industry is responding to these challenges with new initiatives to improve the sustainability profile of flexible packaging. These include technologies to drive recycling and collection and auto-sortation at scale of flexible materials; new materials, including compostable or biobased structures; and enhanced processing technologies that extend and increase consumer participation.

 

 

There are several industry collaborations that are working to identify technologies to make collection and sortation of flexible packaging waste feasible and economically effective, as well as research into chemical recycling, which degrades the mixed plastics into monomers or basic chemicals to turn into new products. Other programs such as waste-to-energy (WTE), which use the combustible energy from difficult to recycle plastics, are widely used in Europe and Asia, and may provide additional recovery processes in the U.S.
