    Estudo de Reaproveitamento de Filmes de Polietileno para Fabricação de Colchões de Ar Comprimido para Utilização em Embalagens de Produtos Eletroeletrônicos
    (Universidade Federal do Pará, 2011) OLIVEIRA, Macêdo Santos de; Prof. Dr. José Antônio da Silva Souza
    Polyethylene films are widely used in packaging for small products due to their mechanical and thermal properties. This study evaluates the reuse of polyethylene films to replace expanded polystyrene (EPS) packaging with inflated air cushions. The physical and mechanical properties of the material were analyzed after the fusion of layers, verifying its potential for protecting electronic products during transportation

    Aplicação do Método Fuzzy no Controle da Geração de Acetaldeído na Resina PET no Processo de Injeção de Pré-Formas de Embalagens Plásticas
    (Universidade Federal do Pará, 2018) MONTEIRO, Carlos Alberto; MACÊDO, Emanuel Negrão
    In order to control the drying temperature of PET resin in the silo of a plastic injection molding machine during the plastic injection process in industries producing preforms for beverage bottles, it is necessary to carefully regulate the ideal temperature. This impacts the control of Acetaldehyde (AA) generation, a substance that alters the taste of carbonated and non-carbonated drinks. This work aims to develop a tool based on Fuzzy logic to support the control of PET resin drying temperature, allowing specialists to make ideal temperature regulation decisions. The Fuzzy inference model was implemented using Matlab’s Fuzzy toolbox, considering input variables, Fuzzification rules, and output variables based on collected data from the preform injection process. The inference model resulted in more precise management of variables influencing AA generation, estimating an annual cost reduction of R$ 907,200.00 in preform production.
