Intrablock masterbatches provide two functions, i.e. to prevent the blocking of the inner surface of the bag for easy opening, and to provide a microscopic roughness of the outer surface of the bags to avoid the collapsing of the bag stacks.
Further benefits in film and sheet applications, INTRABLOCK facilitate the winding / unwinding process of the rolls. In thermoforming application, it improves the denesting of the thermoformed articles.
