  • Output quantity (kg/hr) :
  • Screw diameter and numbers (pcs.*mm) :
What is the suitable Blow-Up Ratio(B.U.R.)?

The Suitable B.U.R. of LDPE & LLDPE ≒ 2 ~ 3;
The Suitable B.U.R. of HDPE ≒ 6 ~ 8

B.U.R. Calculations:
B.U.R. = [Lay Flat Film Width] * 2 ÷ π ÷ [Die Lip Diameter Size]
B.U.R. = [Bubble Diameter Size] ÷ [Die Lip Diameter Size]
※ π(pi)≒3.1416
