Resumo: Films of sodium carboxymethyl cellulose, sodium alginate and their mixture were evaluated in terms of interactions between the polymers, morphology, water absorption and application as seed coatings. FTIR analysis suggested that only hydrophobic interactions occurred between the polymers. The coating of bean seeds was confirmed by microscopy, indicating the formation of dense and homogeneous films with 7 μm thickness. The obtained films did not affect the germination capacity of the seeds. In summary, the characteristics and properties of the films formed and the water absorption capacity, indicate that these systems are viable for use in seed coating processes.
