PPA (Polymer Processing Aid) masterbatch can be used in monolayer blown films to enhance the film's processing characteristics and overall performance. PPA is a type of additive that can improve various aspects of film extrusion.

PPA can increase the melt strength of the polymer, which is particularly important in blown film extrusion. It allows for better bubble stability and improved control over film thickness, resulting in more consistent films.

PPA can contribute to improved film clarity by reducing haze and enhancing the transparency of the film. Using PPA masterbatch can lead to more consistent film properties, such as thickness, appearance, and mechanical properties, resulting in higher product quality.
