Title: SEALABLE PACKAGING LAMINATE WITH NONWOVEN FABRIC
Abstract:
The invention relates to a packaging laminate which is easily tearable and consists of an extrusion-coated nonwoven fabric layer (6) made of a nonwoven fabric (2) of a polymer with a surface weight between 6 to 30 g/m2, wherein an extrusion coating (3) based on a polyolefin with a thickness between 2 and 15 g/m2 is extruded onto a side of the nonwoven fabric (2), and the extrusion-coated nonwoven fabric layer (6) is connected to a laminating adhesive layer (5) with a base layer (7) which comprises at least one sealing layer (4) based on a sealable thermoplastic polymer with a thickness of 10 to 100 µm, wherein the laminating adhesive layer (5) is provided between the extrusion-coated side of the extrusion-coated nonwoven fabric layer (6) and the base layer (7).
