Wanwisa Jankaen, Sasiwimol Janthasit, Kaewjai Pumsawangkaew, Sunthari Rupsung and Payom Srihongsathey helped Thailand win the event for a seventh successive time.
Myanmar took silver while Laos and Vietnam were joint third.
In the men's event, also a round-robin competition, Thailand beat Malaysia 21-16, 21-8 in their last match for their fourth win in a row.
It was the Thai men's fourth straight gold medal and 11th overall.
The Thai players were Pornchai Kaokaew, Thanawat Chumsena, Siriwat Sakha, Sahachat Sakhoncharoen and Pattarapong Yupadee. Malaysia were second while Myanmar and Laos third.
There are 10 events in sepak takraw at the Myanmar Games with each country allowed to take part in a maximum six events. Thailand have won five of their six events.
Thailand, who had won in the men's and women's team events and men's hoop takraw, are hot favourites to triumph in their last event _ the women's doubles.
Thawat Kumutpongpanich, a Thai sepak takraw official, said Thailand should meet their six gold medal target.
"Having won five gold medals, the women's doubles event should not be too tough for us," he said.
While Thailand have been the dominant force in Southeast Asia for years, Thawat said it would be tougher at the Asian Games because several countries have improved considerably.
"South Korea are probably stronger than Malaysia," he said. "The Koreans have trained very hard and learned a lot from us."
There are six gold medals up for grabs at the 2014 Asian Games to be held in South Korea and Thawat said the hosts were good enough to win some.
