Abstract
A paperboard laminate is described. The paperboard laminate includes a first paperboard layer. The first paperboard layer is printable on at least one side. A first side of a material that is tear-resistant in one direction is bonded to a first side of the first paperboard layer with an adhesive material. A second paperboard layer is bonded to a second side of the material with an adhesive material. The second paperboard layer is printable on at least one side.
Claims20
A paperboard laminate comprising:
- a first paperboard layer, the first paperboard layer being printable on at least one side;
- a material that is tear-resistant in one direction, a first side of the material being bonded to a first side of the first paperboard layer;
- and
- a second paperboard layer bonded to a second side of the material, the second paperboard layer being printable on at least one side.

A method of manufacturing a paperboard laminate, the method comprising:
- providing a material that is tear-resistant in one direction, the material having a tear resistance in the one direction of at least 300 grams of force as measured by the Elmendorf tear propagation test;
- bonding a first paperboard layer to a first side of the material with a first bonding agent;
- and
- bonding a second paperboard layer to a second side of the material with a second bonding agent.

A tear-resistant paperboard laminate comprising:
- a first paperboard laminate comprising:
- a first paperboard layer;
- a first material that is tear-resistant in a first direction, a first side of the first material being bonded to a first side of the first paperboard layer;
- and
- a second paperboard layer bonded to a second side of the first material;
- a second paperboard laminate comprising:
- a third paperboard layer;
- a second material that is tear-resistant in a second direction, a first side of the second material being bonded to a first side of the third paperboard layer;
- and
- a fourth paperboard layer bonded to the second side of the second material;
- and
- a bonding agent that bonds the first paperboard laminate to the second paperboard laminate such that the first direction of the first material is substantially perpendicular to the second direction of the second material to provide resistance to tearing in multiple directions.
