Research Gauges Consumer Understanding of Packaging and Food Waste Reduction

American households are the largest contributor to food waste in the nation, representing 40% of the staggering 120 billion pounds of food wasted each year. New research from the Michigan State University (MSU) School of Packaging sheds light on how consumers’ understanding of packaging technology may help combat this growing problem.

Minding the Gap: Consumer Awareness of Packaging & Food Waste Reduction, a new white paper summarizing MSU’s research, offers key insights into types of wasted food, package design strategies, and opportunities to better educate consumers about the features and value of packaging to help them reduce food waste in the home.

The study was sponsored by AMERIPEN, the American Institute for Packaging and the Environment, and the Environmental Research and Education Foundation (EREF).

Types of Food Wasted & Packaging Considerations

The study, which gleaned and analyzed data from a questionnaire distributed nationwide to over 1,000 respondents of varying demographics, found that fruits and vegetables, prepared foods, and dairy are the most frequently wasted food categories in American households. Packaging, or a lack thereof, is a strong influencing factor on food freshness and waste in these categories.

More than half (56%) of fresh whole fruits and vegetables—the most wasted food group cited by participants—were not packaged and frequently spoiled before consumption. Based on those findings, the researchers assert that some fresh food products, especially produce, could benefit from packaging to extend their shelf life and thereby reduce food waste.

Researchers also found that consumers prefer packaging that more clearly states the shelf life of food products and that active and intelligent packaging technologies, which help consumers identify freshness, could further reduce household food waste.

What Consumers Know—and What They Don’t

When researchers polled consumers about their packaging preferences about in-home food waste reduction, respondents prioritized food freshness, package resilience, and product dating as most important. Researchers also found when study participants were better informed about specific packaging technologies, they often stated a willingness to––and in some cases a preference for––purchasing food contained in packaging that helps reduce food waste. Some would even spend more money on such products.

While this data gives industry leaders an incentive to develop even more sophisticated food protection technologies, the study also found that many U.S. consumers don’t fully understand how different types of packaging can preserve food and stretch household food budgets.

“While participants showed some understanding of how packaging protects against physical damage, they were not adept at identifying the best structural packaging designs for keeping different types of food fresh,” said Dr. Eva Almenar, the study’s lead researcher. “Specifically, the impact of only three out of 15 structural packaging designs on maintaining food freshness was known by more than 50% of respondents.”

Korey Fennell, a student who performed the study, said, “Only 30% or less of respondents understood advanced packaging technologies for freshness, including intelligent packaging, modified atmosphere packaging, active packaging, aseptic packaging, and retort packaging.”

How Industry Can Help

The study concludes with several recommendations for industry. In terms of design, consumer packaged goods (CPG) brand owners can develop packaging that extends shelf life upon opening. They should also continue to develop packaging designs that indicate the shelf life of the food product. When thinking about consumer education, the researchers suggest launching consumer awareness and education initiatives that teach people about the various packaging technologies, formats, and features that keep food fresh.

“Extending shelf life is just one of many strategies food packaging designers must consider, and this study reinforces that. While we have made great strides with innovations to reduce food waste, they are underutilized if consumers don’t recognize their value,” said Dan Felton, Executive Director of AMERIPEN. “There is great opportunity here, and industry and government can together take a proactive stance in addressing this critical issue.”

“While MSU’s study is an important first step, there is more work to be done,” said Bryan Staley, President and CEO of EREF. “Specifically, the report suggests additional study into how consumers use advanced packaging technologies—a worthy cause in the name of innovating for waste reduction and the circular economy.”
