Abstract
The present paper produced biodegradable films with polyaprolactone and starch-cellulose from the green banana peel (Musa Paradisiaca) as a possible alternative for the replacement of plastic covers. The process for the extraction of starch-cellulose was carried out using the wet method and basic hydrolysis, suggesting 12 different formulations in which the amount of glycerin and polyaprolactone was modified. The physical, mechanical, optical, functional and biodegradable characterization was developed with reference to standards: ASTM E96-80, D-882-18, D5488- 944, INEN 2636:2012 and scientific articles. The results showed that the biodegradable film had a significant difference in its solubility but not in the opacity and absorption of water; the tension and permeability depend on the formulation type, in addition, it was met at the established thickness and a degradation is projected in a maximum of 30 days. It was concluded that films with a higher amount of polyaprolactone have an improvement in mechanical, functional, physical and biodegradable properties, with a higher degradability compared to conventional plastics.
