The packaging market in Brazil has shown steady growth, driven by factors such as increased consumption, technological innovations, and a focus on sustainability. In the food sector, the choice of specific packaging is crucial to preserving quality, protecting consumers' health, and meeting sustainability criteria. Among the available options, flexible plastic packaging, especially the Bag system, stands out for its high protection capacity, practicality, and efficiency in preserving food quality and safety. This study conducted a literature review on food packaging, focusing on flexible packaging and highlighting its efficiency as barriers against moisture and oxygen. Additionally, it emphasized the importance of bag technology, a solution that combines strength and efficiency in the storage and transportation of food. The study addressed the properties of the materials used, applicable regulations, and the relevance of flexible packaging in the current food industry landscape. However, compliance with food safety standards and challenges related to sustainability remain significant concerns. It is concluded that the continuous development of food packaging technologies, such as the bag system, is essential to meet market demands and environmental concerns, promoting practical and efficient solutions for the industry and consumers alike.

The construction industry in Brazil plays a significant role in economic growth and job creation in the country, contributing substantially to GDP while also promoting urban development and essential infrastructure. Additionally, the sector helps reduce the housing deficit. Given its importance, the aim of this study was to analyze the concentration of the national construction industry between 2012 and 2022. To assess market concentration in the sector, four indicators were used: market share, concentration ratio, concentration curve, and the Hirschman-Herfindahl index. In addition to these indicators, the Structure-Conduct-Performance model was also employed to provide theoretical support. Within the sector, the 50 largest companies. At the end of the analysis, the indicators showed that the sector is not highly concentrated, suggesting a lower likelihood of practices that could harm competition. However, the analysis indicated a certain stability in market shares, with few changes from year to year.
