Depending upon
a. Operational parameters
b. Lay flat width
c. Thickness
d. Polymer properties
e. MFI
f. Ambient temperature
g. Relative humidity
h. Air currents around the extruder
i. Plant voltage variations
- Material processibility: LDPE, LLDPE, HDPE
- Film thickness tolerance: Film thickness variation shall be within +/-10 percent.
or +/-5 microns, whichever is higher at 90 percent measuring points of the film circumference. The remaining +/-10 percent of the measuring points will be +/-5 percent beyond the above-mentioned tolerance.
Note: As width reaches maximum range mentioned above, the thickness of the film proportionately decreases within the parameter of the lay-flat mentioned in the quotation & vice-versa.
Preheating of granules is essential for better quality of film.
In case materials of different MFI are mixed, please consult the raw material manufacturer.
