description | A presente divulgação fornece um processo. Em uma modalidade, o processo inclui o alongamento de um filme multicamadas para conferir um valor de turbidez superior a 30% ao filme multicamadas. O filme multicamadas possui pelo menos duas camadas: (A) uma camada de núcleo composta por um copolímero de etileno/-olefina multi-bloco e (B) uma primeira camada superficial em contato com a camada de núcleo, a camada superficial composta por um polímero a base de etileno. O processo inclui liberar a força de alongamento do filme multicamadas alongado para formar um filme multicamadas turvo com um valor de turbidez superior a 30%. O processo inclui esticar o filme multicamadas turvo para formar um filme multicamadas esticada com um valor de clareza superior a 80%. O processo inclui relaxar a força de estiramento do filme multicamadas esticado para formar um filme multicamadas relaxado com um valor de turbidez superior a 30%.
The present disclosure provides a process. In an embodiment, the process includes elongating a multilayer film to a impart a haze value greater than 30% to the multilayer film. The multilayer film has at least two layers: (A) a core layer composed of an ethylene/α-olefin multi-block copolymer and (B) a first skin layer in contact with the core layer, the skin layer composed of an ethylene-based polymer. The process includes releasing the elongating force from the elongated multilayer film to form a hazed multilayer film having a haze value greater than 30%. The process includes stretching the hazed multilayer film to form a stretched multilayer film having a clarity value greater than 80%. The process includes relaxing the stretch force from the stretched multilayer film to form a relaxed multilayer film having a haze value greater than 30%. |
