Download scientific diagram | A, Microperforation and B, cross section of micro-perforation as seen under SEM of BOPLA film with λ MD × λ TD of 4.0 × 4.0 perforated by CO 2 laser at fluence of 35.5 J/cm 2 from publication: Effect of biaxial-simultaneous stretching conditions on OTR and CO 2 permeation of CO 2 laser perforated poly(lactic acid) film | The biaxially oriented poly(lactic acid) films prepared using simultaneous biaxial stretching were perforated by CO2 laser with the power of 60 W. The focal spot diameter was fixed at 103 μm. Pulse durations were varied from 1 to 30 μs, which corresponds to the fluence from | Films, Motion Pictures as Topic and Film | ResearchGate, the professional network for scientists.
