摘要：
Biodegradable films were obtained from potato starch mixed with montmorillonite nanoclay (MMT), glycerol and the addition of acetic acid, by the casting method; and then characterize them. It was observed that according to the increase in the presence of MMT nanoclay in the film, this improved the elastic modulus and water vapor permeability; while the increase in glycerol had the opposite effect on the properties evaluated. On the other hand, with scanning electron microscopy it was observed that the surfaces of the films were homogeneous. Being the film, of composition 1 ml of glycerol and 0.05g of MMT nanoclay an alternative to being used as food packaging since it has better properties compared to those that only presented glycerol in its formulation.
