The flow of a low-density polyethylene (LDPE) in the entry regions of slit dies with various contraction ratios was studied experimentally for difference temperatures and throughputs. Laser-Doppler velocimetry was used to investigate the flow kinematics upstream of the contraction plane. For the LDP
