Abstract

The paper reinforced tapes and reinforcement elements of this invention have improved repulpability, recyclability, compostability and biodegradability. Further, these reinforcement elements and paper reinforced tapes, despite being predominately paper, unexpectedly provide excellent container reinforcement properties and further can be used as opening tapes, closing tapes, tear tapes and carrying handles.

Claims (34)

1. A container comprising a tear tape, the tear tape consisting of:

a continuous paper strip having a first and second side and further having

a basis weight of from 50 to 300 grams/square meter,

a first layer of adhesive composition disposed on the first side, and

a layer of release material disposed on the second side,

wherein the tear tape is secured to the container by the adhesive composition, and

wherein one end of the tear tape is exposed on the exterior of the container.

2. The container of claim 1 selected from the group consisting of:

a. a first container comprising,

i. a substrate having a first layer and a second layer; and

ii. the tear tape secured to at least the first layer or the second layer such that the tear tape is located between the first layer and the second layer,

b. a second container comprising,

i. a substrate having at least one exterior surface; and

ii. the tear tape secured to at least one exterior surface of the substrate.

3. The container of claim 2 wherein the substrate is selected from the group consisting of paper, paper board, and non-paper.

4. The container of claim 1 wherein the tear tape is completely naturally sourced.

5. The container of claim 1 wherein the continuous paper strip comprises paper having a basis weight of from 75 to 200 grams/square meter.

6. The container of claim 1 wherein the continuous paper strip has a width of from 1 mm to 50 mm.

7. The container of claim 1 wherein the adhesive composition is a pressure sensitive adhesive composition.

8. The container of claim 1 wherein the adhesive composition is selected from the group consisting of water soluble and water dispersible.

9. The container of claim 1 wherein the first layer of adhesive composition and the layer of release material have the same composition.

10. The container of claim 1 wherein the release material is selected from the group consisting of polyethylene, polypropylene, silicone, naturally sourced versions thereof, and combinations thereof.

11. The container of claim 1 wherein the release material is pre-coated onto the second side of the continuous paper strip.

12. The container of claim 1 wherein the tear tape further includes a design element selected from the group consisting of perforation, slitting, folding and combinations thereof.

13. The container of claim 1 wherein the tear tape passes Part I of the Fibre Box Association Test Method.

14. The container of claim 1 wherein the tear tape passes Part I of the Fibre Box Association Test and Modified Fibre Box Association Test Part II.

15. The container of claim 1 wherein the continuous paper strip has a basis weight of from 100 to 300 grams/square meter.

16. A container comprising a reinforcement element, secured to a portion of the container, wherein the reinforcement element consists of:

a continuous paper strip having a first and second side,

a first layer of adhesive composition disposed on the first side, and

a layer of release material disposed on the second side, wherein the reinforcement element is secured to the container by the adhesive composition, the continuous paper strip having a basis weight of from 50 gsm to 250 gsm.

17. The container of claim 16 , wherein the adhesive composition is a hot melt adhesive composition.

18. The container of claim 16 wherein the adhesive composition is selected from the group consisting of water soluble and water dispersible.

19. The container of claim 16 wherein the continuous paper strip has a basis weight of from 100 gsm to 250 gsm.
