1, stretch film net-like structure causes: pigment content is too high, poor heat resistance, pigment masterbatch in water. Solution: lower the temperature in the district, appropriate masterbatch drying, choose a pigment with high intensity, choose the paint with good heat resistance, strengthen hair drier, raise the water temperature.

2, stretch film covering power is bad reasons: low titanium dioxide content in the membrane solution: increase the masterbatch dosage, improve titanium dioxide content in the masterbatch, the titanium white R type.

3, stretch film colored point on the reason: pigment dispersion bad solution: choose good pigment dispersion, strengthen pigment grinding.

4, processing with smoke causes: masterbatch volatiles more solution: reduce the extrusion temperature, use high temperature resistant dispersant.
