Abstract
La presente invención refiere a un método para formar un envase a partir de una preforma de polietileno de alta densidad mediante moldeo por soplado de estiramiento por inyección en uno o dos pasos. El método incluye insertar la preforma en un molde. La preforma tiene una longitud axial de preforma. El método también incluye el moldeo por soplado de la preforma en el molde para formar el envase, incluyendo estirar la preforma para formar el envase con una longitud axial de envase que es de 2.5 a 5 veces mayor que la longitud axial de la preforma.
