Biaxially oriented metalized polystyrene sheet (BOPS metalized)

Thickness range 100÷800 mic.

Application: confectionary trays, sweets inlays, gift packaging.



img1

Metalized oriented polystyrene sheet is a transparent or colored substrate, being one-side aluminum coated in vacuum. Metalized effect is achieved by reflections of the light rays from the surface of the aluminum layer coming through the colored BOPS layer.
