Abstract
The present invention provides a biodegradable plastic prepared from non-edible starch (tamarind seeds) which contains w/w tamarind seed powder (3-6%), gelatin (0.5-2%), Micro-crystalline cellulose (Traces) and v/v of Vinegar (1-3%) and glycerol (2-6%). The product has a Gas Transmission rate of 168.48 cc/m2 day; water vapor transmission rate of 0.067 g/m2/day and tensile breaking force of 34.41 N. The product of the present invention has widespread industrial application e.g. in manufacture of biodegradable art objects/household objects, carry bags, packaging material etc. and also biomedical field e.g. bandages, dressings, sutures. Other potential uses include biodegradable diaper parts, biodegradable sanitary napkins etc.
Claims
1. A biodegradable plastic from non-edible natural polymer WHEREIN the same comprises of the following composition:
And WHEREIN the same has technical characteristics as below:
1) Gas Transmission rate of 168.48 cc/m2 day;
2^ Water vapour transmission rate of 0.067 g/m2/day;
3) Tensile breaking force of 34.41 N.
2. A process for making the biodegradable plastic as claimed in Claim 1 WHEREIN the process involves the following steps:
Roasting of seeds: on hot sand to remove moisture;
Grinding and sieving: of the powder to produce fine powder; Preparation of solution: by addition of different substances in specific amount's viz. gelatin (0.5-2%), cellulose (traces), vinegar (1-3%), glycerol (2-6%) and final volume was made up with water followed by stirring to avoid clump formation and give solution of even composition;
PC17IN2016/000234
15
Centrifugation and heating: The mixture was then centrifuged at 20,000 rpm for 10 minutes followed by heating for 4 minutes with coritinuous stirring to prepare a very fine and even paste, which was then spread on an even glass surface and
Drying: The layer was air-dried at Room temperature and room humidity for 48 hours to produce a thin sheet of biodegradable plastic.
