Excessive plastication / scorch

The essence of excessive plastication (scorch) is thermo-oxidative degradation of material at high temperature. The core of the solution is similar to extrusion degradation — "three controls": control banburying and roll temperature not to exceed limits, shorten material residence time in high-te...

Poor plastication

The essence of poor plastication is insufficient temperature or inadequate mixing time preventing the resin from fully melting. The core of the solution is "heat up + extend time + adjust formulation": increase feed temperature and banburying time, select resin powder with smaller particle size t...

Calendering wrinkles

The essence of wrinkles is inconsistent speeds of various parts of the film surface passing through the roll nip or asymmetric tension distribution. The core of the solution is to ensure uniform roll gap and stable tension control — adjust the roll gap to eliminate local speed differences and opt...

Roll sticking / roll wrapping

The essence of roll sticking is that the adhesion force between melt and roll surface exceeds the separation force required for normal stripping. The solution approach is "cool down + adjust angle + add additives": reduce that roll's temperature to reduce adhesion force, adjust the stripping angl...
