Blowing ratio is one of the control points of blown film production process, is refers to the film after blowing bubble diameter and not blowing the ratio between the pipe ring diameter.Blowing ratio of thin films of lateral expansion ratio, is actually to transverse tensile membrane, will have a certain degree of orientation effect of plastic molecules, blowing ratio increases, thus increase the lateral strength of thin film.


When, after leaving the die by cooling ring on membrane bubble of wind blowing area for cooling, cooling air blowing at certain Angle and speed just out from the plastic bubble, high temperature membrane bubble with cooling air contact, membrane bubble of heat will be taken away by the cold air, clear the decrease of the temperature to the low density polyethylene.
