The present invention relates to a composition for use in packaging. More particularly, the present invention relates to a biopolymer-based nanocomposite, an article of manufacture and a method of production thereof. The biopolymer-based nanocomposite comprises a nanocellulose and a polyvinyl alcohol, wherein an anionic surfactant is used in dispersion of the nanocellulose in the polyvinyl alcohols matrix. The biopolymer-based nanocomposite has excellent mechanical properties, reinforcing capability, low weight and biodegradable.
