Plastic

Explanation:

Thermo flasks have 2 chambers- inner chamber and outer chamber.
The inner chamber is for the storage of water while the outer chamber is made up of plastic or a metallic case.
The two chambers are separated by 2 layers of glass or stainless steel in case of the unbreakable flask, which has a reflective metal lining. It also has a vacuum in between.
To make them spill-proof, there is a tight, screw-down stopper at the top.
These layers prevent the loss of heat through conduction, convection, and radiation.
