The present application relates generally to a process of manufacturing an optimized packing material comprising chia seed mucilage (CSM), glycerol, and sorbitol, wherein said packaging materials have a good tensile strength (2.005 N/mm.sup.2), lower water vapor permeability (1.73×10.sup.−9 g×s×Pa/m), a good flexibility (e.g. high elongation at break, 31.729%). The optimum conditions of polyol concentration were 1.3 g of glycerol and 2.0 g of sorbitol per g of CSM. Based on these results, chia seed mucilage can successfully be used to develop biofilms with potential to be used in drug delivery and edible food coating applications. Both the process and the products are within the scope of this application.

The invention relates to a method of making a paper product 10, 10.01 to 10.14, wherein the method includes the step of adding natural reinforcing material (31, 31.1, 51, 51.1, 61, 61.1, 71, 71.1) to one of: a) a layer of pulp as it exits or after it exits from a layer formation process or apparatus; or b) a tank 20, 20.1, 20.2 of pulp prior to it exiting from a layer formation process or apparatus; or c) a combination of a) and b). Additionally, the invention relates to paper products made by this process. The present invention also provides a multi-layered material 2.10, 2.10″, 2.10.1, 2.100 to 2.1600, and 100 to 1900, and a layer treatment of a layer or layers of a multilayered material, and a multilayered material which has had such a layer or layers treated by such a layer treatment.
