20220203658 · 2022-06-30 · ·

The present patent application relates to a method of manufacturing a multilayered composite film comprising a step of co-extruding at least three layers (a), (b) and (c), of which the layer (a) forms an outward surface of the composite film; the layer (c) forms a surface of the composite film facing or coming in contact with a good to be packaged; and the layer (b) is disposed between the layer (a) and the layer (c). Further, the method includes a step of biaxial orientation of the composite film thus co-extruded. Therein, the layer (a) contains or consists of a thermoplastic resin. The layer (b) contains or consists of a polyvinylidene chloride (PVdC) resin. The layer (c) contains or consists of a resin, preferably sealable, in particular heat-sealable resin. Therein, any crosslinking of the composite film by means of radioactive radiation, in particular by means of beta, gamma, X-ray and/or electron irradiation, is omitted during the manufacturing of the composite film and/or thereafter.

Process to manufacture multilayer laminated packaging material
11731415 · 2023-08-22 ·

The invention refers to a process to manufacture multilayer laminated packaging material. More particularly, the invention relates to processes to manufacture multilayer laminated packaging material used to produce carton packages, in especially aseptic carton packages containing liquid or pasty products. A plurality of layers is continuously laminated onto a non-printable face of a paperboard layer to form a semi-finished web of multilayer laminated packaging material. Next, the inner face of a translucent thermoplastic protective material having a commercial artwork printed onto its printable inner face is laminated onto the not printed printable face of said semi-finished web of multilayer laminated packaging material, wherein the artwork with numbers, letters and drawings is printed in a reverse position regarding to what was supposed to be when seeing the artwork from the opposite not printed outer face of said translucent thermoplastic protective material.
