Abstract

A casting tape package system is provided comprising an outer package defining a first interior portion enclosing a casting tape substrate including curable casting formulation and a second interior portion enclosing a curing agent. In certain embodiments, the curing agent is separated from the casting tape substrate by a barrier which is breakable to release the curing agent to activate the curable casting formulation.

First claim

What is claimed is:

1. A casting tape package system comprising:
an outer packaging, said outer packaging including a first interior portion and a second interior portion;
a casting substrate, wherein said casting substrate is a roll of fabric, and wherein said casting substrate is located in the first interior portion and includes a curable casting formulation;
a curing agent, said curing agent located in the second interior portion;
a barrier disposed within the outer packaging and separating the first interior portion from the second interior portion, the barrier breakable to allow the curing agent to admix with the casting substrate, wherein the barrier is configured to form a sealed bladder, said sealed bladder being separately formed and received within an interior compartment defined by the outer packaging; and
a tearing notch indicating a line of preferential tearing for ease of opening of the casting tape package system.

2. The casting tape package system of claim 1 , wherein the outer packaging is formed of a polymer film.

3. The casting tape package system of claim 1 , wherein the curable casting formulation is a curable resin.

4. The casting tape package system of claim 3 , wherein the curable resin is a water curable pre-polymer resin and the curing agent is water.

5. The casting tape package system of claim 3 , wherein the curable resin is a polyurethane pre-polymer.

6. The casting tape package system of claim 1 , wherein the roll of fabric is selected from the group consisting of a polyester fabric, a fiberglass fabric, and an open-weave fabric.

7. The casting tape package system of claim 1 , wherein the barrier is formed of a material having one or both of:
a line of preferential breaking; and
a tensile strength which is lower than a tensile strength of the outer packaging.

8. The casting tape package system of claim 1 , wherein the barrier is formed of a polymer film.

9. The casting tape package system of claim 1 , wherein the casting substrate is impregnated with the curable casting formulation.
