摘要

A MULTIPLE LAYER OF POLYPROPYLENE IS DESCRIBED, WHICH COVERS AT LEAST ONE BASIC LAYER, CONTAINING POLYPROPYLENE OR A MIXTURE OF POLYPROPYLENE AND RESIN, AND AT LEAST ONE COAT LAYER, CONTAINING ONE MIXTURE AND ONE MIXTURE OF II AND A MIXTURE OF TWO. COMPONENT I CONTAINS ESSENTIALLY A PROPYLENE HOMOPOLYMER OR A COPOLYMER OF ETHYLENE AND PROPYLENE OR ETHYLENE AND BUTYLENE OR PROPYLENE AND BUTYLENE OR ETHYLENE AND ANOTHER ALPHA-OLEPHINE WITH 5 TO 10 ATOMS OF CARBON OR PROPHYL OLEPHONE ATOMS OF CARBON OR A TERPOLYMER OF ETHYLENE AND PROPYLENE AND BUTYLENE OR ETHYLENE AND PROPYLENE AND ANOTHER ALPHA-OLEPHINE WITH 5 TO 10 CARBON ATOMS OR A MIXTURE OF TWO OR MORE OF THE KNOWN HOMOPOLYMERS, COPOLIMEROS, OPOLIMEROS MORE OF THE KNOWN HOMOPOLIMEROS, COPOLIMEROS AND TERPOLIMEROS, EVENTUALLY MIXED WITH ONE OR MORE OF THE KNOWN HOMOPOLIMEROS, COPOLIMEROS AND TERPOLIMEROS. COMPONENT II CONTAINS ESSENTIALLY ONE HDPE OR A MIXTURE OF TWO MIXING COMPONENTS A AND B. COMPONENT A IS ESSENTIALLY AN HDPE. COMPONENT B IS ESSENTIALLY A PROPYLENE HOMOPOLYMER OR A COPOLYMER OF ETHYLENE AND PROPYLENE OR ETHYLENE AND BUTYLENE OR PROPYLENE AND BUTYLENE OR ETHYLENE AND ANOTHER ALPHA-OLEPHINE 5 TO 10 ATOMS OF CARBON OR PROPYLENE-O-PROPYLENE-5 ATOMS OF CARBON OR A THERPOLYMER OF ETHYLENE AND PROPYLENE AND BUTYLENE OR ETHYLENE AND PROPYLENE AND ANOTHER ALFAOLEFINE WITH 5 TO 10 CARBON ATOMS OR A MIXTURE OF TWO OR MORE THAN KNOWN HOMOPOLYMERS, COPOLIMEROS OF TWO AND ONE THE KNOWN HOMOPOLYMERS, COPOLYMERS AND THERPOLYMERS. THE SHEET IS MATE.
