Specifically designed for the production of BOPP matt films on stenter or double-bubble lines

The products are based on special selected α-Olefine grades. The surface roughness and matt appearance of BOPP films are resulting from our knowledge to combine suitable polymers.

Typical applications of matt compounds are:

  •  Translucent, opaque and coloured (e.g. gold, silver) films that require a
     matt appearance
  •  Heat-sealable packaging films
  •  Metallizable films with matt effect (steel appearance)
  •  Matt films with high coefficient of friction (COF) for packaging films with
     anti-skid properties

All required film properties such as low gloss, high haze and soft touch effect can be achieved by using the CONSTAB Matt Compounds.
Typical optical properties of a 15–18 µm matt film:

Gloss (45°):     10-12 units (matt side)
                       45-55 units (glossy side)

 Haze (ASTM D 1003):     > 65 %

  • MAT 02440
    is a heat-sealable matt compound for packaging films
  • MAT 02442
    is a special grade matt compound for metallizable films
  • MAT 02444
    is a heat-sealable matt compound with high COF for anti-skid properties

All grades are easy to process and avoid the “die driveling” phenomenon.
Skin layers of coextruded BOPP films consist of 100 % matt compound.

To achieve a good matt effect a skin layer between 2 and 4 µm is recommended.

We can offer the combination of many years of experience, high quality and solid expertise in order to create the best suitable product for customer needs.
