Abstract
Official abstract text for this publication.
The present disclosure is directed to films. The films can include polyamic acid (PAA). Methods of making and using the film for food product coverings is also included.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of packaging a food material, the method comprising: covering at least a portion of the food material with a film, the film comprising polyamic acid (PAA); glutaraldehyde (GA); and a small molecule selected from the group consisting of 2-benzylbenzoyl (BB), polycaprolactone (PCl), D-glucosamine (DA), dipropylene glycol (DP), p-aminosalicylic acid (pAS), sulfanilic acid (SA), and 5-aminosalicylic acid (5AS). 2. The method of claim 1 , wherein the film is provided on a roll, the film provided with a predetermined width and a predetermined length. 3. The method of claim 1 , wherein the small molecule is 2-benzylbenzoyl (BB). 4. The method of claim 1 , wherein the small molecule is polycaprolactone (PCl). 5. The method of claim 1 , wherein the small molecule is D-glucosamine (DA). 6. The method of claim 1 , wherein the small molecule is dipropylene glycol (DP). 7. The method of claim 1 , wherein the small molecule is p-aminosalicylic acid (pAS). 8. The method of claim 1 , wherein the small molecule is sulfanilic acid (SA). 9. The method of claim 1 , wherein the small molecule is 5-aminosalicylic acid (5AS). 10. A method of monitoring food spoilage of a food product, the method comprising: applying a polyamic acid (PAA) film to at least a portion of the food product, wherein the film comprises a small molecule selected from the group consisting of 2-benzylbenzoyl (BB), polycaprolactone (PCl), D-glucosamine (DA), dipropylene glycol (DP), p-aminosalicylic acid (pAS), sulfanilic acid (SA), and 5-aminosalicylic acid (5AS); and monitoring the film for a change in at least one of a color of the film and a conductivity of the film. 11. The method of claim 10 , wherein the small molecule is 2-benzylbenzoyl (BB). 12. The method of claim 10 , wherein the small molecule is polycaprolactone (PCl). 13. The method of claim 10 , wherein the small molecule is D-glucosamine (DA). 14. The method of claim 10 , wherein the small molecule is dipropylene glycol (DP). 15. The method of claim 10 , wherein the small molecule is p-aminosalicylic acid (pAS). 16. The method of claim 10 , wherein the small molecule is sulfanilic acid (SA). 17. The method of claim 10 , wherein the small molecule is 5-aminosalicylic acid (5AS).
