In this work, the use of infrared radiation as curing media to graft eugenol ontocellulose for bioactive paper obtaining is proposed with the aim to obtain a processcompatible with typical processes for papermaking. Eugenol is grafted ontocommercial papers using polycarboxylic acid as linking agent using infrared heating forreaction curing. The effect of different operation and design variables, such as power,time, and distance to heat source were analyzed using an experimental design.Optimal IR curing parameters were determined analyzing reaction degree, mechanicalproperties and color by response surface methodology. The operation conditions werecompared with laboratory, pilot and industrial scale background concluding that thebioactive paper production could be adapted with the current papermaking processdoing feasible scaling the bioactive paper production. The modified paper presentsinsectifuge and antimicrobial properties. A decrease in the biodegradability rate wasobserved, however, the biodegradable characteristic is conserved
