The packing film composite for film packaging of goods, e.g. pet food, or hygiene items, comprises a transparent, non-stretchable outer film (1) having an outer layer (5), a core layer (6) and a concealment layer (7), a heat-sealable inner film (3), and a core film (2) arranged between the inner and outer films. The surface forming the outer film has a measuring angle of 10[deg] . The material of the outer film has a hardness of less than 40 Shore D and a bending module of 290-370 MPa at room temperature. The outer- and inner films and the core film are coated with adhesive.

The outer- and inner films and the core film are coated with adhesive. The outer film is co-extruded and is formed in symmetrical manner by blow molding extrusion. The total thickness of the packing composites is 100-180 mu m. The thickness of the outer film is 20-40 mu m. |
