Food waste is a barrier to the development of sustainable food systems, and a large portion of it occurs at the household level. Household food waste can be decreased by using appropriate packaging. Despite the high rate of food waste in US households, little is known about how packaging affects this. This study assessed US consumers’ awareness of how structural packaging designs and technologies affect food freshness and their willingness to purchase and to pay extra for packaging designed to reduce household food waste. To gather data, 1000 US consumers were surveyed online. Responses were analyzed overall and by population segments. The impacts of only 3 out of 15 structural packaging designs on maintaining food freshness were known by >50% of consumers. Regarding packaging technologies, while 78% of consumers knew about the impact of vacuum packaging on maintaining food freshness, just 27.6, 23, and 16% knew how modified atmosphere packaging, active packaging, and aseptic packaging affected food freshness. Only 32% of consumers knew that intelligent packaging provides information on food freshness. Just 9% of consumers recognized that foods in plastic pouches and cans possess the same food freshness. Approximately 91% of consumers will always/sometimes buy food in most of the above packaging technologies after learning about them. Half were willing to pay more for food in packages that reduce household food waste, and 40% may. Differences (p ≤ 0.05) and two-way interactions were observed between population segments. This study’s findings can help develop new packaging, education campaigns, and policies to reduce household food waste in the US.
