Driving toward a goal of using more sustainable materials in packaging, two Alexia Organic Potatoes brand products from potato producer Lamb Weston will use corn and potato starch in their packaging beginning in April 2021.
UPDATE: The package, reported on here in 2021, has more recently won a 2022 Flexible Packaging Award for Sustainability. Read about all of 2022 FPA Award Winning technologies by clicking here.
The packaging is partially made of potato starches, a byproduct of producing French fries. Research by GlobalData (March 2021) indicates more than 3 in 10 U.S. consumers believe environmentally friendly packaging material is a key driver of a purchase.
Alexia’s Organic Sweet Potato Fries and Organic Yukon Select Puffs will feature a special seal, identifying the plant-based packaging. Lamb Weston’s packaging team spent two years collaborating to create a sustainable packaging alternative and continue working to expand their sustainable packing efforts.
“Sustainability is a pillar of our packaging innovation strategy. By combining efforts with teams across the business we were able to create something innovative that will not only help reduce our carbon footprint, but also continue to deliver to our customers,” says Deb Dihel, Vice President of Innovation.

The new bag material lamination replaces a legacy oriented polypropylene (OPP) bag with LLDPE sealant layer.
“The bio-material is replacing LLDPE of our sealant layer,” says Casey Bettendorf, Senior Mgr Packaging Engineering on the Innovation Team. “OPP has proven to have many advantages that support our retail business, from its machineability to graphics. This effort is to reduce our footprint by utilizing more renewable resources at this point. Work is underway to expand this concept into a fully recyclable design.”
In the new lamination, 16% of the complete structure has been replaced with plant-based material. Annualized across both items equates to removing 8,928 lbs of PE and replacing it with bio-based material and a 6.5-ton reduction in CO2 emissions.
“Lamb Weston has a robust supply chain. We had to make sure that the structure could meet all of our quality and operational requirements,” Bettendorf says. “Packing French fries using v/f/f/s [vertical form/fill/seal] tends to put a lot of stress on our material so good seals, puncture, and tear resistance is critical to ensure we can provide a quality product to our customers.
Converter and flexible packaging supplier American Packaging Corporation (APC) provides the flexographically printed rollstock for this application. According to APC, the environmental impact annually* of using a packaging substitute for the Alexia Organic Potato equates to:
· 14,700 miles driven
· 252 trash bags in landfill
· 750,000 phones charged
· 98 trees over 10 years
· 14 barrels of oil
*Utilized 3.0 mil LLDPE (low density polyethylene) sealant film with 20% biomaterial by weight. 6.5 reduction in net CO2 emissions. PW
