BOPET film is a type of high quality plastic films using the biaxial oriented stretch (transverse and machine direction) technique.  The film is light-weight, non-toxic, odorless, transparent, glossy, temperature and moisture-resistant, and retains high barrier resistance, making it suitable for many forms of flexible packaging, printing, laminating, aluminum-plating and other processes.  In addition, it retains high dielectric strength and volume resistance even at high temperatures, which are essential qualities for electrical and electronic uses.

There are two types of BOPET films by thickness/application in the market place.  One is the commodity film (10~50μm, mainly for packaging) and the other is the specialty film (50~300μm or under 8μm, mainly for imaging, electroinc and electrical industries, magnetic products).

BOPET films have been widely used in consumer based packaging and imaging (such as masking film, printing plates and microfilms), electronics and electrical (such as wire and cable wrap, capacitors and motor insulation) industries, as well as in magnetic products.  Due to its unique qualities, it is suitable for application in the food, pharmaceutical, cosmetics, tobacco, and alcohol industries and has become a popular choice as a flexible packaging material in these industries in recent years.
