The ratio of the blown diameter to the extruded diameter is known as the blow-up ratio, and affects the resulting physical properties of the film, such as stiffness and strength.
Conditions for the existence of the convolution may be tricky, since a blow-up in "g" at infinity can be easily offset by sufficiently rapid decay in "f".
Goddess than had and intense, emotional blow-up, stating that she was the outcast, the vote were based on popularity and accused the team deliberately alienated her.
Film thickness and blow-up ratio can be varied by altering the take-up rate of the rollers, the internal pressure in the blown tube, and the melt extrusion rate.
