Summary:
Barrier materials are ubiquitous in consumer materials. They are used to prevent oxygen permeation in food packaging, water barrier for protective coatings and fuel barrier for flame retardancy. However, many of the materials utilized to perform these functions are not sustainable. Fortunately, nature has already solved many of these problems. Here a discussion of some selected research into utilizing cellulose nanomaterials as barrier layers in food packaging will ensue. Cellulose nanomaterials have gained a lot of notice recently owing to their impressive mechanical and thermal properties, environmental benefit, low toxicity and possible low cost. Processing, characterization and resultant package level testing will be presented.
