Poor optical film
The optical properties of blown film are influenced by the material type, temperature, and die gap size. Here are common checks and solutions:
Frost Line Too High:
Lower the height of the frost line to improve optical clarity.
Molten Temperature Too Low:
Increase the temperature of the extruder and die head to optimize melt flow and transparency.
Melt Fracture:
Refer to the Solution of Melt Fracture for further guidance on fixing melt issues.
Too Wide Die Gap:
Replace the die pins with narrower ones to improve film thickness and optical consistency.
Formulation or Additive Issues:
Excessive anti-block agent or improper additives can affect film quality. Use higher-flow index and lower-density polymer, and optimize additive levels for better results.
