CONTROLE DE QUALIDADE NO PROCESSO PRODUTIVO DE EMBALAGENS FLEXÍVEIS: RELATO DE EXPERIÊNCIA DE ESTÁGIO SUPERVISIONADO

Abstract

Flexible packaging plays a fundamental role in the protection, preservation, and commercialization of food products, requiring high quality standards to ensure safety, performance, and compliance with technical specifications. 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.
