In this context, the present study aimed to analyze the importance of laboratory quality control in the production process of flexible packaging through a supervised internship experience conducted in a company within the packaging industry. Initially, a literature review was carried out addressing the main polymers used in the manufacture of flexible packaging, the stages of the production process, including extrusion, printing, lamination, and finishing, as well as concepts related to quality management and quality control. During the internship, activities involving visual and dimensional inspection, coefficient of friction (COF) determination, refrigeration resistance testing, ink solids analysis, thermal shrinkage testing, thickness measurement, and document management in the quality records archive were monitored. The results demonstrated the relevance of laboratory testing for identifying nonconformities, monitoring production processes, and ensuring the quality of the final products. Furthermore, the importance of traceability and standardized procedures was observed as essential tools for continuous improvement and compliance with market requirements. It was concluded that laboratory quality control is indispensable for ensuring the reliability of flexible packaging, contributing to food safety, customer satisfaction, and the competitiveness of the industry.

This work describes the activities developed during the supervised internship in a flexible packaging industry, analyzing the production process and the rigorous quality control system, which are indispensable for food safety. The experience provided a systemic view that begins in the Research and Development (R&D) sector, where participation in sample development was fundamental to validate structures and ensure compatibility among resins, adhesives, and printings before large-scale production. On the factory floor, the internship emphasized the control of critical variables in extrusion, such as thickness monitoring to ensure barrier properties and the film's machine performance. Subsequently, the flexographic printing and lamination processes were monitored, understanding the synergy between substrates such as Polyethylene Terephthalate and Polyethylene—a union necessary to provide gloss, resistance, and sealability to the complex. In the finishing phase, the practice focused on optimizing cutting-and-sealing parameters to guarantee hermetic seals through the interpenetration of molecular chains. The central component of the internship was quality control, where analytical methods were applied to determine the grammage of components using precision balances. This integrated approach allowed the technical classification of defects into critical, major, or minor, consolidating the importance of constant monitoring for operational excellence and compliance with market demands.

The process begins with the receipt of soybeans, followed by the stages of cleaning, drying, oil extraction, refining, and transesterification, until obtaining the final product. Throughout the process, critical control points were identified, at which essential analyses are performed to ensure quality. Among the analyses performed, notable ones include the determination of moisture, acidity index, soap content, phosphorus, chlorophyll, oxidative stability, flash point, kinematic viscosity and water content. The results obtained were compared with the limits established by regulatory agencies, such as ANP and MAPA, highlighting the compliance of the biodiesel produced with current specifications. The experience provided practical application of the knowledge acquired throughout the Food Engineering course, contributing to the development of technical skills and critical thinking in the area of quality control. As a result of the performance during the internship, there was confirmation in the position of laboratory analyst, emphasizing the importance of practical experience for entry into the job market.

Look for these correct foods for a portion of the population that seeks to reduce the consumption of calories, sugars or fats, or that have specific dietary needs. The research was carried out using an online questionnaire, which covered demographic data, frequency and motivation of consumption, in addition to knowledge about the terms light and diet. The results demonstrated that, although there is a growing interest in these products, a significant part of consumers do not clearly understand the differences between them. It should also be noted that the consumption of light and diet products is more associated with weight control and medical restrictions, however, many consumers use them in inconvenient ways, which can lead to health risks. Data analysis suggests the need for educational campaigns to inform the public about the properties and limitations of these products, in addition to pointing out that the high price is a factor that limits regular consumption. It is concluded that financial accessibility and broader nutritional education could Light and diet products have been gaining more and more prominence worldwide, with an exponential increase in consumption.
