Polypropylene

As base film we use a biaxially oriented polypropylene film (BOPP film) made especially for metallizing which has high mechanical strength and good dielectric properties.

This film can be metallized either with pure aluminum (99.98 %), zinc or zinc-aluminum alloy.

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:

Single side margin right / left

Single side margin right / left with heavy edge type BLEND

Double internal series


Double internal series with heavy edge type BLEND

Other designs like multiple internal series, step, tapered and segment metallization and many others on request.
