When we arrived at the gate and opened the flight deck door; the Purser reported that both aft galley flight attendants briefly smelled a burnt plastic smell during the taxi to the gate. A Maintenance write up was reported and a call was placed to Maintenance Control and Dispatch. The First Officer and I stayed with the local tech ops team and flight attendants to fill out the smoke checklist and to trouble shoot the issue. After researching the issue; it was found to be deice fluid being sucked into the APU during the start. No further action taken.
B737 Captain reported being notified by Flight Attendant crew of 'burnt plastic' odor during arrival taxi.
