High strength adhesive tape
A high strength adhesive tape. The high strength adhesive tape includes a scrim layer and a fabric layer. The high strength adhesive tape also includes a first adhesive layer, where the first adhesive layer attaches the fabric layer to the scrim layer. The high strength adhesive tape further includes a second adhesive layer, where the second adhesive layer is configured to form a bond between the high strength adhesive tape and an external object.
1. A high strength adhesive tape having an upper surface and a lower surface, with the lower surface configured for adhering to an external object, the high strength adhesive tape comprising:
a scrim layer on the upper surface;
a fabric layer between the upper surface and the lower surface;
a first adhesive layer between the scrim layer and the fabric layer, wherein the first adhesive layer attaches the fabric layer to the scrim layer; and
a second adhesive layer on the side of the fabric layer opposite to where the fabric layer is attached to the scrim layer.
2. The high strength adhesive tape of claim 1 , wherein the second adhesive layer forms the lower surface of the tape and is configured to form a bond between the high strength adhesive tape and the external object.
3. The high strength adhesive tape of claim 1 , wherein expansion rate of the scrim layer is approximately equal to an expansion rate of the fabric layer.
4. The high strength adhesive tape of claim 1 , wherein the scrim layer comprises a film.
5. The high strength adhesive tape of claim 4 , wherein the scrim layer comprises a polyethylene terephthalate film.
6. The high strength adhesive tape of claim 4 , wherein the film is transparent.
7. The high strength adhesive tape of claim 4 , wherein the film comprises designs of an aesthetic nature or is colored.
8. The high strength adhesive tape of claim 1 , wherein the scrim layer comprises a fabric.
9. The high strength adhesive tape of claim 1 , wherein the scrim layer is between 40 μm and 60 μm thick.
10. The high strength adhesive tape of claim 9 , wherein the scrim layer is approximately 50 μm thick.
11. The high strength adhesive tape of claim 1 , wherein the fabric layer comprises polyethylene fabric.
12. The high strength adhesive tape of claim 1 , wherein a grammage of the fabric layer is between 85 g/m 2 and 130 g/m 2 .
13. The high strength adhesive tape of claim 12 , wherein a grammage of the fabric layer is between 105 g/m 2 and 110 g/m 2 .

19. The high strength adhesive tape of claim 18 , wherein a gram mage of the second adhesive layer is approximately 85 g/m 2 .
20. A method of producing a high strength adhesive tape, the method comprising:
providing a scrim layer;
coating a first side of the scrim layer with an adhesive;
treating a second side of the scrim layer with an anti-stick agent, wherein the second side of the scrim layer is opposite the first layer;
providing a fabric layer;
attaching a first side of the fabric layer to the first side of the scrim layer using the adhesive on the first side of the scrim layer; and
coating a second side of the fabric layer with an adhesive, wherein the second side of the scrim layer is opposite the first layer.
21. The method of claim 20 , further comprising the step of corona treating the fabric layer.
22. The method of claim 20 , wherein attaching the first side of the fabric layer to the first side of the scrim layer includes allowing the adhesive to cure.
