Mylar® 800 is a clear, non-pretreated base film with high gloss, low haze and excellent processability.
|
|
Polyester film is more thermally stable at higher temperatures and has a higher tensile strength than materials such as polyproyplene and polyethylene. Mylar® 800 polyester film is stiffer than polypropylene and also maintains an excellent film thickness profile and roll formation to ensure consistent processability. These characteristics will enable Mylar® film to process at higher speeds, temperatures and tensions, thus increasing line efficiency and productivity.

|
Mylar® 800 film features good clarity and handling characteristics in metallizing operations. When aluminum metallized, the film exhibits excellent aesthetic quality as well as the best barrier to oxygen and moisture in a flexible film.
