Abstract
USO DE POLIETILENO RECICLADO EM FECHAMENTOS PARA GARRAFAS. Misturas de polietileno feitas de polietileno reciclado e uma composição de polietileno bimodal são descritas. As misturas de polietileno são adequadas para aplicações de moldagem por compressão ou moldagem por injeção e são particularmente úteis na fabricação de tampas e fechamentos para garrafas.
