Q
Excessive shrinkage of linear low-density polyethylene extruded products
Q
Linear low-density polyethylene PE raw material has a wide temperature window, making process parameter optimization difficult
A
PE temperature window optimization needs to be advanced from two aspects: systematic experiments and experience accumulation.

Q
Frequent screen change/short screen life of linear low-density polyethylene extruder
Q
Poor printability of linear low-density polyethylene film
Q
Longitudinal retraction rate of linear low-density polyethylene pipes exceeding standard
Q
Insufficient heat seal strength of linear low-density polyethylene film
A
Insufficient heat seal strength is caused by improper temperature, pressure or time settings; heat seal process parameters need to be optimized.

Q
Unstable output/surging in the linear low-density polyethylene extrusion process
A
Unstable output is caused by unstable solid conveying; barrel temperature and the feeding system need to be optimized.
