Different Types of Mylar
Mylar is a material that is often mistaken for aluminum foil. It is a thin, flexible plastic sheet that can be used to wrap around objects. There are different types of mylar, ranging from the cheapest version to the more durable.
In general, a mylar bag has three layers: the middle layer is made of polyester film and the outer layer is made of BoPET (Biaxially-oriented Polyester). These three layers make for a high quality film.
Metallized mylar is a special type of mylar film. This type of mylar is coated with a very thin metal sheet. The metallic appearance is reminiscent of aluminum foil.
Metallized films are used for specialty applications. They offer a glossy metallic appearance and are commonly used for decorative purposes. Their benefits include reduced weight and cost.
Aluminum coated polyester film is one of the most common applications for this type of film. This type of film has a shiny metallic appearance and is also highly reflective. Many people use the material as an insulator, as it reflects heat.
Aluminized mylar is another option. This type of mylar is coated on the surface with a thin metal sheet. Like the regular version, aluminized mylar is a flexible, durable plastic that combines the benefits of both aluminum and Mylar.
