Abstract
LA PRESENTE INVENCION SE REFIERE A UNA PELICULA RETRAIBLE MEJORADA, OBTENIDA REGULANDO Y OPTIMIZANDO SELECTIVAMENTE EL DIFERENCIAL DE DENSIDAD ENTRE, AL MENOS, DOS COMPONENTES POLIMEROS DE POLIOLEFINA, DE FORMA QUE OBTENGA VARIACIONES DE DENSIDAD REDUCIDAS. ESTA INVENCION SE REFIERE, POR UNA PARTE, A UNA PELICULA RETRAIBLE DE POLIOLEFINA ORIENTADA BIAXIALMENTE QUE TIENE UNAS PROPIEDADES EQUILIBRADAS, Y POR OTRA PARTE, UNA PELICULA RETRAIBLE ORIENTADA CUYA TENACIDAD ESTA MEJORADA. ESTA INVENCION SE REFIERE FINALMENTE A UN PROCEDIMIENTO DE ORIENTACION BIAXIAL QUE PERMITE LA FABRICACION DE UNA PELICULA RETRAIBLE UTILIZANDO UNAS TECNICAS DE ORIENTACION DE REFRACCION COMO POR EJEMPLO EL CUADRADO DE RAMA, LA DOBLE BURBUJA, LA BURBUJA CON TRAMPA, UNA ORIENTACION DE BANDA O SUS COMBINACIONES. EL PRIMER COMPONENTE ES, PREFERENTEMENTE, UN INTERPOLIMERO DE ETILENO/ AL - OLEFINA CASI LINEAL CON BAJA DENSIDAD Y EL SEGUNDO COMPONENTE ES UN INTERPOLIMERO DE ETILENO/ AL - OLEFINA RAMIFICA DO DE MODO HETEROGENEO CON DENSIDAD ELEVADA.
