20220315306 · 2022-10-06 · ·

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.

Water-, oil- and grease-resistant multilayer coating for paper-based substrate and uses thereof

The present invention relates to a water-, oil- and grease-resistant multilayer coating for a paper-based substrate comprising a water-based inner primer coating, an intermediate polymeric extrusion coating, and a water-based top barrier coating, wherein a surface of the paper-based substrate coated therewith has water, oil and grease barrier properties, and wherein the paper-based substrate coated therewith is repulpable and recyclable.
