Development of biodegradable and antibacterial packaging paper using a bilayer film based on nanocellulose from Bolaina (Guazuma crinita) forest residues with the incorporation of copper nanoparticles for the food industry

This project focuses on the production of a new packaging material, which will be manufactured using the Bolaina waste, which will be used to obtain nanocellulose. This material, due to its physical properties, allows it to give resistance and hardness to other materials, making it ideal for obtaining paper or films. The packaging paper that is proposed as a substitute for the food packaging that is currently used, which is based on non-recyclable or biodegradable polymers such as technopor or polyethylene, will be made from the nanocellulose of bolaina forest residues, which They will replace the virgin pulp that is used to produce the paper and nanocellulose will also be used to obtain the bilayer film that will accompany the packaging paper so that it is resistant to humidity. An important ingredient is the addition of copper nanoparticles (CUO) that will be added to the film
bilayer to eliminate bacteria that may form when in contact with food. This will help prevent food from spoiling when packaged.
