Lifestyle factors play a significant role in food decision-making, and food choices are often linked to the perception of packaging as a powerful tool for providing information. The goal of the research is to analyse the impact of packaging on the preferences of generations Y and Z and to identify differences in their behaviour and attitudes. For this, primary data obtained through survey research were used, where respondents answered questions about demographics, packaging preferences and lifestyle. The results were analysed using the statistical package SPSS Statistics. The results of the research indicated differences between generations Y and Z in terms of food product packaging preferences. Generation Z shows a greater preference for more modern and innovative packaging designs, while Generation Y may prefer more classic or traditional designs. Both generations show a high sensitivity to environmentally friendly materials, emphasizing the importance of sustainability in packaging production. The practicality of the packaging is also highly rated by both generations, while the information on the packaging is valued equally. In terms of food preferences, Generation Y emphasizes healthy eating habits such as eating fresh fruits and vegetables, while Generation Z shows more interest in an active lifestyle and a balanced diet. The social aspect of eating also differs, with Generation Y preferring socialization through shared meals, while Generation Z prefers a more individual approach. In conclusion, although there are differences, both generations are sensitive to quality, sustainability and information, which can help manufacturers and marketers to better adapt their products and strategies. The professional contribution of this research lies in a deeper understanding of the preferences of generations Y and Z and their influence on the purchase of food products, and the obtained results can serve as a basis for adapting marketing strategies and products according to their needs.
