Compostable Food Packaging Material And Method For Producing
A food packaging material, a method of making such a material, and a substantially completely compostable package made from such material, are disclosed. The packaging includes constructions wherein a single ply or double ply of substantially completely compostable substrate layers sealingly-engaged to one another using a natural food-grade contact adhesive, advantageously results in a substantially completely compostable natural food packaging material. The method utilizes existing commercial machinery and processes to form compostable substrates into packaging, including application of print indicia.

- 1. A substantially completely compostable packaging material for a food comprising:
a flexible sheet layer having an outer surface and an inner surface; a layer of cold-seal release coating disposed on an area of the outer surface of said sheet layer; an ink disposed on an area of the outer surface of said sheet layer for color, print and imaging; a cold seal cohesive disposed on areas of the inner surface of said sheet layer and in contact with said food, wherein the sheet layer is a naturally organic compostable material that is substantially completely biodegradable.
- 2. A substantially completely compostable packaging material for a food comprising:
an outer first flexible sheet layer; a layer of cold-seal release coating disposed on outer first flexible sheet layer; an inner second flexible sheet layer disposed inwardly toward said food, relative to said outer first flexible sheet layer; an ink disposed for color, print and imaging on said second flexible sheet layer; a cold seal cohesive disposed on areas of the inner surface of said inner second sheet layer and in contact with said food, wherein each of the sheet layers is a naturally organic compostable material that is substantially completely biodegradable.
- 3. A method of making a substantially completely compostable packaging material for a food comprising the steps of:
providing a first flexible sheet layer; disposing a cold-seal release coating onto an area of the outer surface of said first sheet layer; providing a second flexible sheet layer inwardly toward said food relative to said first sheet layer; applying a glue or laminating adhesive on the outer surface of said second or inner surface of said first flexible sheet layer; printing color and graphic indicia onto an area of the inner surface of said first sheet layer; disposing a cold seal cohesive layer onto areas of the inner surface of said second sheet; wherein the first flexible sheet layer and the second flexible sheet layer is a naturally organic compostable material that is substantially completely biodegradable.
- 4. A method of making a substantially completely compostable packaging material for a food comprising the steps of:
providing a first flexible sheet layer; disposing a cold-seal release coating onto an area of the outer surface of said first flexible sheet layer; printing color and graphic indicia onto an area of the outer surface of said first flexible sheet layer; disposing a cold seal cohesive layer onto areas of the inner surface of said first flexible sheet layer; wherein the first flexible sheet layer is a naturally organic compostable material that is substantially completely biodegradable.
