A blown film screw barrel plays an important role in melt quality, output stability and film thickness control.

For LDPE, LLDPE and HDPE film extrusion, screw design should match the resin, L/D, rotation speed and required output. An unsuitable or worn screw can cause poor plasticizing, unstable extrusion, higher melt temperature and reduced production capacity.

When replacing a blown film screw barrel, choosing the correct screw geometry and wear-resistant material can improve production stability and service life.
