Acesso em:.https://repositorio.ufpa.br/handle/2011/8032Films of polyethylene (PE) are commonly used in packaging of small products such as packaging for digital cameras, camcorders, wine bottles, medical instruments, etc... as a function of important properties such as mechanical strength (vibration, drop, etc..) thermal (temperature, humidity, pressure) with the ease of processing and a cost. In electronics packaging, are used PE films of low density, depending on the product being package. In this work, films were evaluated as lowdensity polyethylene used for packing display panels on the production line, consisting of a single polymer, replacing the packaging of expanded polystyrene (EPS) by a polyethylene cushion with air mattress inflated with changes in the thickness of the films were subjected to the fusion of two layers of training for air mattresses, under certain conditions of temperature and pressure, where expansion of the films resulted in significant changes in physical, mechanical. The films were characterized before and after welding for clothing of air mattresses in the format of columns of air that can be molded into packaging for consumer electronics. It was observed that change according to the type of material making up the films of polyethylene, that is, the more resistant to compression test, the greater the degree of impact absorption when this raw material in the form of inflated air mattress this means an excellent performance to bear the weight of a product during the mechanical test, such as drop test, vibration test, test temperature and humidity. Studies show that we can study and test films with high strength and are discarded and reprocessed in the factories for the manufacture of inflatable cushions to be used in various products. The reuse of these raw materials helps to reduce the rate of waste disposed in the environment.Acesso AbertoPolietilenoEmbalagensFilmes plásticosReaproveitamento (Tecnologia química)Colchão de ar comprimidoFilmes de polietileno (PE)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA MECANICA::PROCESSOS DE FABRICACAO
