PEN FILM (polyethylene naphtalate)

As base film we use a biaxially oriented, temperature resistant polyethylene naphtalate film.

Due to its good mechanical, thermal and electrical properties, this film - which is similar to polyester - is especially suitable for applications in extreme environments. The main properties of polyester film are surpassed by PEN.

This film is metallized with pure aluminum (99.98 %).

The electric resistance (metallization strength) and the kind of metallization will be according to the customer's requirements.

Here are our standard kinds of metallization available:

One side metallization with margin right / left
One side metallization with heavy edge type BLEND and margin right / left
Internal 2-section series with one side metallization
Internal 2-section series with one side metallization and heavy edge type BLEND

Other designs like internal series, double side metallization, tapered and segment metallization and many others on request.
