Q
POE extrusion film longitudinal streaks
Q
POE film blocking, difficult delamination
Q
POE extrusion profile bending deformation
A
Profile bending is caused by uneven cooling and uneven flow velocity; uniformization and alignment are the solution key

A
Q
POE extrusion film thickness uniformity poor
Q
POE film heat shrinkage too large
A
Film heat shrinkage is caused by orientation freezing; reducing draw ratio and annealing treatment are key
