Machine Needed-: Rotational Speed: 600 to 70 r/min Blow-up Ratio: 4 to 5 Pulling Speed: 80 to 150 r/min Screw L/D Ratio: L/D=24/32, in the reference of ¢ 45 single screw extruder. Precision Temperature Control: ± 5°C Filler installment: 120 mesh-120 mesh (two levels) from inside to outside. Remarks-: At the beginning of film blown process, pulling speed has to be slow because of the cooling effect. The pulling speed can be slowly increased after the film blown process, becomes stable, but maximum pulling speed shall not exceed 150r/min. Blown bubble needs to be cooled by vane in time, but the temperature shouldn’t be too low. Greater blow-up ratio is good for achieving sufficient tensility, which helps to improve strength. Stable pulling and cooling will be needed if film bubble is not stable.
