Abstract
A method of making a cover includes the steps of providing a heat shrinkable film constructed at least in part from a first styrenic block copolymer, providing a composite layer, providing an adhesive layer between the film and the composite layer, the adhesive layer including a second styrenic block copolymer selected from the same family as the first styrenic block copolymer, and laminating the film to the composite layer.
Claims28
A method of making a cover, including the steps of:
- providing a heat shrinkable film having an inner layer, an outer layer, and a first styrenic block copolymer incorporated into the inner layer but not the outer layer, the first styrenic block copolymer incorporated into the inner layer in an amount equal to at least 30% by weight of the inner layer but less than 50% by weight of the inner layer;
- providing a composite layer;
- providing an adhesive layer between the inner layer of the film and the composite layer, the adhesive layer including a second styrenic block copolymer selected from the same family as the first styrenic block copolymer;
- and
- laminating the film to the composite layer.

A method of making a cover, including the steps of:
- providing a heat shrinkable film having a first side, an edge, an inner layer, an outer layer, and a first styrenic block copolymer incorporated into the inner layer but not the outer layer, the first styrenic block copolymer incorporated into the inner layer in an amount equal to at least 30% by weight of the inner layer but less than 50% by weight of the inner layer;
- providing a composite layer having a first side opposite the first side of the film and an edge, wherein the edge of the film and the edge of the composite layer are located between the first side of the film and the first side of the composite layer;
- providing an adhesive layer between the composite layer and the one of the inner layer or the outer layer into which the first styrenic block copolymer is incorporated, the adhesive layer including a second styrenic block copolymer selected from the same family as the first styrenic block copolymer;
- laminating the film to the composite layer;
- providing a moisture permeable edge wrap for facilitating the migration of moisture through the edge of the film and the edge of the cover;
- and
- securing the edge wrap to the first side of the film and the first side of the composite layer such that the edge wrap at least partially surrounds the edge of the film and the edge of the composite layer after laminating the composite layer to the film.

- providing a composite layer;
- providing an adhesive layer between the inner layer of the film and the composite layer, the adhesive layer including a second styrenic block copolymer selected from the same family as the first styrenic block copolymer;
- laminating the film to the composite layer;
- and
- wherein the inner layer has a content of less than 50% first styrenic block copolymer.
