If you’re looking to make the packaging process more eco-friendly, the obvious place to start is with the box itself. And that’s exactly what Salt Lake City-based Packsize did when it made its initial foray into sustainable packaging back in 2002. That year, the company launched its first product, an innovative on-demand packaging system designed to reduce cardboard waste (and the need for filler material) by creating a right-sized box for each shipment.
Now the company is ready for the next step: greening up the glue.
According to Packsize, 300 billion boxes around the globe are sealed using 500,000 tons of hot-melt adhesive every year, contributing significantly to global emissions generated by the paper-based packaging industry. In a bid to cut those emissions, Packsize recently teamed up with Henkel Adhesive Technologies, a unit of the German chemical and consumer goods company Henkel, to launch Eco-Pax, a bio-based hot-melt adhesive designed to lower carbon footprints without sacrificing performance.
Eco-Pax is made from bio-based raw materials, forgoing traditional fossil-based ingredients. The adhesive will soon be used on more than 340 million boxes produced annually using Packsize’s right-sized packaging machines. That single change is expected to reduce Science Based Targets Initiative (SBTi)-relevant greenhouse gas (GHG) emissions up to 32%, which is equivalent to the burning of 1.75 million pounds of coal, the partners said.
“Partnering with an innovative leader like Packsize to launch a bio-based adhesive solution is a big step toward building a more sustainable packaging value chain,” Kevin Heffernan, head of business development, North America, consumer goods adhesives, Henkel Adhesives Technologies, said in a release. “Together, we’re setting a new standard for sustainability in packaging while delivering the high-performance brands and consumers trust.”
