Patent ID: 7276294

Claim:
A laminate structure consisting of: a paperboard substrate having an inner surface and an outer surface; a layer of a heat-sealable polymer coated on the outer surface of the paperboard substrate; a first layer consisting of nylon 6 layer coated on the inner surface of the paperboard substrate; a first tie layer coated on an inner surface of the first nylon 6 layer; at least one layer of polyolefin polymer coated on an inner surface of the first tie layer; a second tie layer positioned on an inner surface of the at least one layer of polyolefin polymer; a second nylon 6 scalping barrier layer on an inner surface of the second tie layer; a third tie layer positioned on an inner surface of the second nylon 6 layer; and, a heat-sealable polymer layer coated on an inner surface of the third tie layer.
