MYLAR® 813

Product Description

Mylar® 813 is a clear, pretreated base film with high gloss, low haze, and excellent processability. It is a one side pre-treated polyester designed for improved ink adhesion.

General Product Info

Mylar® 813 film provides good clarity for reverse printing and allows inks to shine through with high quality. The film's pretreated surface also provides improved adhesion for various coatings and adhesives, often eliminating the need for any type of priming operation. The chemical pretreatment on Mylar® 813 film does not result in a performance or shelf life decline over time, and generally is superior to corona treated film.

Mylar® 813 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 packaging film.

Polyester is more thermally stable at higher temperatures and has higher tensile strength than materials such as polypropylene or polyethylene. Mylar® polyester film also maintains an excellent film thickness profile and roll formation to ensure consistent processability in your operations. These characteristics are particularly important in complex, multi-stage printing operations where holding print register is critical to print quality. As print complexity, quality and speeds increase, Mylar® film provides a cost-effective solution for the packaging industry.
