The objective of this research is to investigate the melting and the burning characteristics of polyethylene film in microgravity field. This experiment was conducted using Drop Experiment Facility in Micro-gravity Laboratory of Japan. The flame and the droplet became spherical shape in micro gravity field. For 850K and 900K temperature in the furnace, the droplet diameter first increased and then decreased due to occurrence of expansion and vaporization before polyethylene film ignited. After ignition, droplet diameter suddenly increased, and then decreased. For the 950K temperature in the furnace, the droplet diameter increased gradually until polyethylene film ignited. After ignition, droplet diameter, d, suddenly increased, and then d^2 decreased lineally, showing d^2 low.
