Abstract: The present invention relates generally to the field of food packaging, in particular food packaging. One embodiment of the present invention relates to a three/dimensional cellulose/based food packaging with excellent barrier properties. For example, the present invention relates to a cellulose-based, multilayer, three-dimensional food packaging comprising a bioplastic layer, a barrier paper layer and a moulded cellulose layer. This cellulose-based, multilayer, three-dimensional food packaging has an oxygen transmission rate (OTR) of less than 30 cc/m2/d (23° C., 50% RH) and a water vapor transmission rate (WVTR) of less than 20 g/m2/d (38° C., 90% RH).

Abstract: This invention relates to the composition of a chitosan coated paper wherein the chitosan may be derived from a variety of sources. Methods of using chitosan as a surface coating or pulp additive to tune the properties of paper and paperboard products are also described. The chitosan applied is a bio-based and environmentally friendly barrier coating and/or additive material for the manufacture of functional paper and paperboard products, specifically as evaporative cooling media requiring wet strength and structural integrity, wicking, and moisture resistance as an alternative to conventional phenolic-based resins. The solid-state fermentation method to produce chitosan and its derivatives offer renewable bio-based materials towards the manufacture of functional paper products that are eco-friendly but also offer uncompromised performance levels.
