GESTÃO DO PROCESSO DE IMPRESSÃO FLEXOGRÁFICA DE EMBALAGENS PLÁSTICAS FLEXÍVEIS

Abstract

This paper presents an account of the activities carried out during a curricular internship at a flexible plastic packaging manufacturing plant, focusing on supporting the flexographic printing process and ink room operations. The objective was to describe and discuss the controls implemented for ink receipt and usage, the monitoring of variables such as color, viscosity, and drying time, sample preparation for comparison, and the use of operational data to support decision-making. Activities included verifying the technical specifications of incoming batches, conducting Zahn cup No. 2 tests, determining drying times, performing colorimetric evaluations, recording setup times and production events, and managing inventory and material requisitions. The experience demonstrated that the stability of the printing stage relies on the integration of raw materials, printing components, operational parameters, and standardized procedures. Systematically monitoring these variables enhances traceability, reduces the need for machine adjustments, and helps prevent waste. The activities also highlighted the connection between Food Engineering coursework and the production of packaging for the food industry, particularly regarding quality control, standardization, good practices, data analysis, and process management.
