How to measure glass transition temperature the most usual test method to determine glass transition temperature of plastics is astm e1356.
Mylar glass transition data sheet.
Mylar can be aluminized by evaporating a thin film of metal onto it to reduce its permeability.
Mylar polyester film is a flexible strong and durable film with an unusual balance of properties making it suitable for many industrial applications.

Multiplying the indicated change by the sample length gives the thermal dimensional change in the sheet of mylar.
Mylar a 12 36μm.
As a guide to estimating changes due to thermal expansion figure 5 gives the dimensional changes in in over a wide temperature range.
Type mylar a is a tough general purpose film which is transparent in 12μm through 23μm and translucent in heavier thickness.
