Estudio ergonómico y propuesta de mejora del área de confección de una fábrica de fundas plásticas.

Abstract

This study focused on the ergonomic analysis of the sealing machine operator in the production area of plastic bag manufacturing factory, motivated by the presence of musculoskeletal disorders associated with inadequate workstation design, poor working conditions, and 12-hour work shifts. The objective of the study was to develop an improvement proposal aimed at optimizing work performance and enhancing occupational health. To evaluate factors related to adopted posture, repetitive movements, load handling, and workplace organization, the research was conducted through interviews, direct observations, postural assessments using the REBA and RULA techniques, and surveys. The evaluations indicate that operators adopt constrained postures, work at poorly designed stations, and use inadequate tools, increasing muscle fatigue and the risk of musculoskeletal disorders. Productivity is negatively affected, and absenteeism rises under these conditions. Based on the results obtained, it is recommended to implement a series of improvements, including modifying the workstation, introducing ergonomic tools, workflow to reduce unnecessary movements. These actions area expected to increase efficiency and improve performance quality in the production area.
