Abstract

Un método de moldeo de compresión de un artículo de plástico, tal como un envase, incluye proveer un material polimérico fundido, comprendiendo una mezcla de por lo menos un polímero fundido y un gas mezclado en el mismo. El material polimérico se moldea entre los moldes macho y hembra de cooperación, con movimiento relativo de los moldes controlado para formar una cavidad de molde con un volumen predeterminado. La formación de esta manera actúa para producir un envase moldeado con densidad sustancialmente reducida, logrando así ahorros de material deseados, mientras que proporciona aún un envase o artículo similar exhibiendo características de desempeño deseadas.
