BOPET–Metallized Film
BLF(MO)
Structure
Modified primer coated Skin Layer
Core layer
Un- treated skin layer
Aluminium layer
Description
BLF(MO) is a co-extruded, metallized BOPET film. Metallization on un-treated surface and other side is always modified chemically pre-treated for UV offset printing application. The metal bond between the metal and film is minimum of 150 gm/inch when metallized on the un-treated surface.
Features
- Excellent Machinability & handling properties
- Excellent for board lamination
- Suitable for UV offset ink printing on coated surface side
- Very good treatment retention on coated surface side
- Lamination on metallized surface side
Applications
- This film is specially designed for UV offset printing on chemically coated side.
- Film is majorly use in box/board lamination
