Research on interactive food packaging design based on user experience under the background of dual carbon

Abstract

In recent years, the environmental degradation caused by carbon emissions has become more and more serious. It is particularly important to achieve the dual carbon goals of "carbon peaking" and "carbon neutral". The food packaging process accounts for a large portion of carbon emissions in the food industry and is an important concern for carbon reduction. While the task of carbon reduction is particularly important, it is also important to design food packaging with the user's experience in mind. This is the reason why interactive packaging design, which focuses on two-way communication and user experience, is used in the design of this paper. To corroborate the design scheme, the carbon footprint analysis of three packaging methods for 200g cooked peanuts was conducted in this paper. The final carbon footprints of vacuum, air, and modified atmosphere packaging methods were 36.18, 54.78, and 218.86 gCO2eq respectively. Subsequently, the sensitivity of different packaging methods is analyzed. It is found that vacuum packaging is more sensitive to changes in emission factors. The final carbon footprint value is changed by 16.31% under the direct influence of emission factors, while the final carbon footprint values in air and modified atmosphere packaging are 4.88% and 0.78% respectively, which are less affected by the change of factors.
