Abstract
En el presente documento se proporcionan películas sopladas con agentes activos encapsulados, tales como agentes antimicrobianos volátiles, adecuados para su uso como materiales de envasado de alimentos. También se proporcionan aquí métodos para fabricar tales películas sopladas. Los métodos incluyen extruir una burbuja a partir de polímeros fundidos, dispensar agentes activos dentro de la burbuja y colapsar la burbuja de modo que la burbuja se adhiera a sí misma y forme una película con los agentes activos encapsulados.
