Scope

Scope: This standard applies to double-layer, triple-layer, and five-layer co-extrusion blown film production lines. Single-layer blown film production lines can refer to this standard for implementation. Main technical content: Table 1 - Main technical parameter items and units Five-layer co-extrusion blown film production line SJ (5) - 55/65/75/65/55 - 2000 Three-layer co-extrusion blown film production line SJ (3) - 55/65/55 - 1800 Double-layer co-extrusion blown film production line SJ (2) - 75/75 - 1800 Screw diameter (mm) Φ55/65/75/65/55 Φ55/65/55 Φ75/75 Applicable raw materials - LDPE, LLDPE, HDPE, LLDPE, mLLDPE, HDPE, LLDPE Film blowing width (mm) 1100-1800 1000-1600 1100-1700 Maximum output (IBC + internal cooling) kg/h 400 260 160 Die head diameter (mm) φ400/φ450 φ350/φ400 φ400 Screw length-to-diameter ratio - 30:1 30:1 30:1 Wind ring diameter (mm) 450/500 400/450 450 Main motor power (kw) 37/45/55/45/37 37/45/375/55 Film bubble internal cooling system width accuracy (IBC) mm ±8 ±8 ±8 Winding method - Surface center gap winding or fully automatic back-to-back friction double winding Surface center gap winding or fully automatic back-to-back friction double winding Fully automatic (or manual) back-to-back friction double winding Film blowing deviation accuracy mm ±1.8 ±1.8 ±1.8 Tension control range N/m 0–1000 0–1000 0–100 Tension automatic adjustment accuracy % ±2 ±2 ±2 Maximum sound pressure level dB(A) ≤85 ≤85 ≤85 Optional functions - Implemented according to contract requirements Blown film production line blowing film quality requirements Item Standard Finished film thickness deviation limit Finished film thickness (mm) 0.020–0.050 ±8%–±15% 0.051–0.090 ±7%–±8% 0.091–0.150 ±6%–±7% Film appearance quality - The film appearance should be firm, flat, and clean; the surface should have no obvious wrinkl
