Abstract

This invention relates to paperboard materials for carrying static cling vinyl products for transport to end users. Such structures of this type, generally, provide good adhesion for the static cling vinyl product, but allow the vinyl product to be peeled off easily.

Claims

1. A paperboard carrier for carrying static vinyl products, wherein said carrier is comprised of:

a paperboard carrier base;

an extruded layer of high density polyethylene located exterior to said paperboard base such that said polyethylene layer is cooled and surface treated to provide a predetermined smoothness and surface energy to said polymeric layer; and

a static cling vinyl product operatively attached to said extruded layer.

2. The paperboard carrier, as in claim 1, wherein said carrier is further comprised of:

a layer of particulate minerals located substantially between said paperboard carrier base and said extruded layer.

3. The paperboard carrier, as in claim 1, wherein said particulate minerals is further comprised of:

clay.
