Black spots on poly
(OP)
What is the industy normal on black spots and grains generated from Poly film.
We use jumbo rolls, highest micron is 125mic. and lowest micron is 60mic. We use a 100% HF121 LLDPE Hexene copolymer with medium antiblock and medium slip blend.
Is it 5 per square meter, not to exceed a diameter of 300micron or
no black spots/grains at all?
