The Flexible Packaging Assn. partnered with PTIS LLC to provide a holistic view of the sustainability benefits that flexible packaging offers in e-commerce and to quantify the environmental and economic shipping impacts comparing flexible packaging to other formats across a range of products.
For the report, five different LCA case studies were developed using the EcoImpact-COMPASS® LCA software, which allows for quick life cycle comparisons between different package formats and included a wide range of products including shoes, cereal, peanut butter, laundry detergent, and flat mailers. All primary, secondary, and tertiary packaging, including dunnage from the packages, were used for the assessment. Dunnage is a filler that is used to prevent a product from shifting during shipping, resulting in product damage. Dunnage may be either paper or plastic based, and includes crumpled paper, corrugated inserts, air pillows, and bubble wrap.
Additionally, the product-to-package ratio, as well as the amount of packaging that is landfilled for 1,000 kg of each product, was determined. The amount of packaging landfilled was based on the recycling rates for each material while assuming none of the flexible packages were recycled. However, most flexible packaging used in e-commerce applications, including bubble dunnage or poly mailers, are made of LDPE, which can be recycled with grocery bags and other films as part of the grocery store drop-off program. These materials can qualify for the How2Recycle® store drop-off designation if they go through the certification process.
The results from many of the case studies show that flexible packaging has more preferable environmental attributes for carbon impact, fossil fuel usage, water usage, as well as material disposed of when compared to other package formats. This is due to the efficient use of resources enabled by flexible packaging.
An additional benefit of flexible packaging includes the robust nature of the material, which can help reduce leaks or package breaks, thus significantly improving consumer enjoyment of a product (and brand). This is important in an e-commerce environment where a product is handled at least three times as often as is done within a traditional retail channel.
