Packaging bag and product including the same

Abstract

A packaging bag suitable for containing an article comprises a flexible, environmentally friendly substrate and a layered structure. The flexible, environmentally friendly substrate forms a bag shape to contain the article. The layered structure is disposed on the flexible, environmentally friendly substrate and includes an antistatic agent and a conductive material connected thereto.

Claims

2. The packaging bag as described in claim 1, wherein the number of the at least one antistatic auxiliary layer is two, and the two antistatic auxiliary layers are respectively disposed between the paper layer and the inner layer structure and between the paper layer and the outer layer structure.

3. The packaging bag as described in claim 1, wherein the basis weight of the paper layer is greater than or equal to 150 g / m2.

4. The packaging bag as described in claim 1, wherein the paper layer is white kraft paper.

5. The packaging bag as claimed in claim 1, wherein the at least one antistatic auxiliary layer comprises aluminum metal, or comprises copper and nickel metal.

6. The packaging bag as claimed in claim 1, wherein the sealant, antistatic agent and conductive material of the outer layer are mixed in the same layer.

7. The packaging bag as claimed in claim 1, wherein the sealant, antistatic agent and conductive material of the outer layer are disposed in different layers.

8. The packaging bag as claimed in claim 1, wherein the sealant of the outer layer structure comprises polyurethane, polyethylene acetate, hot melt adhesive, or bio-based resin.

9. The packaging bag as claimed in claim 1, wherein the antistatic agent of the outer layer structure is an aqueous antistatic agent.

10. The packaging bag as claimed in claim 1, wherein the inner layer structure includes an adhesive, and the adhesive, antistatic agent and conductive material of the inner layer structure are mixed in the same layer structure.

11. The packaging bag as claimed in claim 1, wherein the outer layer structure further comprises a release agent, the outer layer structure comprising a first layer structure and a second layer structure stacked together, the first layer structure being located between the flexible environmentally friendly substrate and the second layer structure, the antistatic agent and conductive material of the outer layer structure being mixed in the first layer structure, and the release agent of the outer layer structure being disposed in the second layer structure.

12. A product with a packaging bag, comprising: a packaging bag comprising: a flexible environmentally friendly substrate forming a bag shape; and a layered structure disposed on the flexible environmentally friendly substrate, wherein the layered structure comprises an inner layer structure and an outer layer structure, the inner layer structure being disposed on the inner side of the flexible environmentally friendly substrate and comprising an antistatic agent and a conductive material connected thereto, the outer layer structure being disposed on the outer side of the flexible environmentally friendly substrate and comprising an antistatic agent and a conductive material connected thereto, the conductive material of the outer layer structure comprising carbon black, carbon fiber, carbon nanotubes, graphene or metal powder, and the outer layer structure further comprising a sealant; and an article contained in the packaging bag; wherein the flexible environmentally friendly substrate comprises a paper layer and at least one antistatic auxiliary layer, the at least one antistatic auxiliary layer being located between the paper layer and the inner layer structure or the outer layer structure.

13. The product with a packaging bag as described in claim 12, wherein the layered structure comprises an inner layer structure and an outer layer structure, the inner layer structure being disposed inside the flexible environmentally friendly substrate and comprising an antistatic agent and a conductive material connected thereto, and the outer layer structure being disposed outside the flexible environmentally friendly substrate and comprising an antistatic agent and a conductive material connected thereto.

14. The product with a packaging bag as described in claim 13, wherein the flexible environmentally friendly substrate comprises a paper layer and at least one antistatic auxiliary layer, the at least one antistatic auxiliary layer being located between the paper layer and the inner layer structure or the outer layer structure.

15. The product with a packaging bag as described in claim 14, wherein the number of the at least one antistatic auxiliary layer is two, and the two antistatic auxiliary layers are respectively disposed between the paper layer and the inner layer structure and between the paper layer and the outer layer structure.

16. The product with a packaging bag as described in claim 13, wherein the outer layer further comprises a sealant.
