Abstract
The present invention is related to the elaboration of a compound material molded from cassava flour for the manufacture of biodegradable packaging useful in packing and packaging of dry foods and other products. The semi-rigid novel compound material is elaborated through thermo-pressing of a mixture of cassava flour and fique fiber.
Claims2
A process to produce a semi-rigid biodegradable-type compound material molded by thermo-pressing For the manufacture of packages of dry foods and other products, comprising the stages of:
- (a) Adjust the humidity of the cassava flour to a value between 8 and 10% and diminish its particle size to a range comprised between 250 and 425 μm.
- (b) Dry the fique fiber to humidity between 8 and 11%, and diminish its particle size to a range comprised between 250 and 425 μm.
- (c) Dry mix the cassava flour and the fique fiber and add glycerin and vegetable oil.
- (d) Add to the mixture polysorbate 80 and water in the following proportions:
- cassava flour between 30 and 40% p/p, fique fiber 10 to 20% p/p, glycerin 4 to 5% p/p, vegetable oil 4 to 5% p/p, polysorbate 80 0.5 to 1.5% p/p, and water between 30 and 50%.
- (d) Mold the mixture obtained by thermo-pressing during 2 to 5 minutes at a temperature between 180 and 220° C.
