FIELD OF THE INVENTION
The present invention herein relates to the field of chemistry particularly to a method for making Sustainable and Biodegradable Bioplastic Packaging Material.
BACKGROUND OF THE INVENTION
India produces 198.5 metric tons of milk, and the percentage is increasing every year out of this 198.5 metric tons of milk 20% of milk is packed out of which 85% of milk is packed in plastic pouches. The most important Arena to focus on is that plastic is a non-degradable material that can be in existence for more than a thousand years. Plastic can produce a lot of problems for the environment and also for the living species, this is because of the “CARCINOGENIC” Materials which are used in the production of plastic which plays a major role in causing cancer to the majority of population. Plastic is also involved in various other serious problems for human beings. the plastic which is thrown into the garbage in rural and urban areas causes many problems related to it like a disturbance in the food chain, a decrease in soil fertility, and killing damaging the aquatic life So many different animals eat plastic material and unfortunately die in a study it is mentioned that more than 85% of sea birds have plastic teeth in their stomach Plastic is widely used in packaging, Most of the plastic which is used here in India is coming from the dairy industry which has a major role in degrading the environment. This invention is 100% biodegradable packaging material created by using nonreactive agricultural waste and contributing to saving the environment and to promote sustainable development of smart biodegradable packaging.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
In the present invention agricultural waste like rice bran, wheat Bran, and husk has been used along with glycerol Sodium alginate and gelatin for the development of bioplastic which is 100% biodegradable using gelatin-based film because gelatin have nontoxic and antimicrobial property in these types of bioplastics use sodium alginate as it acts as a thickening agent, and it is an excellent Binder use glycerol for its well binding property. Also, have fixed the micro level sensor which will help in detecting the microbial population as by using this, microbial load in milk can be detected.
Formation of bio plastic, on a hot plate place a Pan in which added 48 grams of gelatin 12 gram of glycerol in 240 ml of water. Which will make 300ml of bio plastic at the temperature of 95 degree Celsius. Stirred it and the bioplastic were formed.
COMPATIBILITY OF BIOPLASTIC WITH MILK
Testing of ph:-
Initially took 30 ml of milk in a beaker and to that dissolved just an inch of bioplastic part and left it in the refrigerator for 2 days maintaining 4 degrees Celsius after 2 days, checked the sensory characteristics detecting colour smell and texture. Then with the help of pH meter, Detected the pH and the pH is 6.82. also, a small portion of bioplastic, dissolved in distilled water and checked the pH and the pH was 6.48.

EXPERIMENTATION:
Step 1 Formation of bran sheet
For the formation of bran sheet first took 25 gram of rice bran sieved it to remove granules rice and heavy rice particles then in grinder grind it which enhance size reduction.
Then add binders’ sodium alginate 6% that is 4 grams and 60 ml bio plastic to the grinded bran after that steam and increased moisture content (16-45%). for the sheet formation made a dough out of it and applied pressure manually by a roller of 15 to 30 kg then once the sheet was formed dry it in tray dryer at (55-65°C) for 1 hour. Meanwhile before the completion of an hour at the interval of 30 minutes provide shape with the sheet at intermediate stage also gave it a cylindrical shape square and cone shape respectively.
Step2 for making bioplastic
On a hot plate placed a Pan in which add 48 grams of gelatin 12 gram of glycerol 240 ml of water at the temperature of 95 degree Celsius which will make 300ml of bioplastic, stirre it and the bioplastic was formed.
Step 3:- procedure for coating
When the sheet of the bran has gone under the process of drying after 30 minutes of drying the sheet is given the shape of the desired choice which may be cylindrical or square at the same time a coating of hot bioplastic must be done the coating must be uniform and should be spread to each and every corner of the bottle or the shape if you have made from the sheet of Bran after that the coated sheet of the bran again go for the process of drying with bioplastic as the internal coating of the same.
Step 4: installation of sensor
Micro sensor: - smart packaging
As milk is a perishable food product it's very important to track the microbial load. So, the micro-level sensor is used.
In the product micro level sensor are fixed which will help in detecting the microbial population because by using this, microbial load in milk can be detected. Also fixing a LED light which will show different color on the increment of microbial number when microbial population increases the turbidity of milk will increases too. So, fixing a turbidity level measuring sensor which will reflect green light, (fresh) gradually yellow (turbidity started) and at last red (spoilage).
All of the above procedure gives us the pH in range of 6 to 7 which prove that bioplastic was comfortable to milk. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
