WE CLAIM:

1. A composition of a bioplastic comprising:

4 to 10 percentage weight of agarose;

50 to70 percentage weight of plasticizer to weight of the agarose;

3 to 10 percentage weight of silicon dioxide (Si02) to weight of the plasticizer; and

3 to 10 percentage weight sodium dodecyl sulphate (SDS) to the weight of plasticizer.

2. A composition of a bioplastic comprising:

6 percentage weight of agarose;

62.5 percentage of plasticizer to weight of the agarose;

6 percentage weight of silicon dioxide (Si02) to the weight of plasticizer; and

6 percentage weight sodium dodecyl sulphate (SDS) to the weight of plasticizer.

3. The composition of the bioplastic as claimed in claimsland 2, wherein the plasticizer is a Polyethylene Glycol (PEG).

4. The composition of the bioplastic as claimed in claimsland 2, wherein the composition of bioplastic is 100 % bio-degradable in natural environment.

5. The composition of the bioplastic as claimed in claimsland 2, wherein the bioplastic is hydrophobic in nature of 80 to 90 percentage at room atmospheric moisture condition.

6. The composition of the bioplastic as claimed in claimsland 2, wherein the bioplastic is hydrophilic in nature of 10 to 18 percentage at room atmospheric moisture condition.

7. A process (100) for preparation of a bioplastic film comprising:

(a) mixing a bioplastic composition with water;

(b) heating the mixture of the bioplastic composition with water at 90 degree Celsius to 100 degree Celsius for obtaining a molten state of the bioplastic composition;

(c) mixing Sodium Dodecyl Sulphate (SDS) to the molten state of the mixture of the bioplastic composition to reduce surface tension; and

(d) spreading mixture of molten bioplastic composition obtained in step

(c) on a flat surface to obtain the bioplastic film.

8. The process as claimed in claim 7, wherein the obtained thin bioplastic film is dried at 60 degree Celsius in a closed chamber for a duration of 18 hours.

9. The process as claimed in claim 7, wherein the bioplastic composition comprises:

4 to 10 percentage weight of agarose;

50 to70 percentage weight of plasticizer to weight of the agarose; and

3 to 10 percentage weight of silicon dioxide (Si02) to weight of the plasticizer.

10. The process as claimed in claim 7, wherein 3 to 10 percentage weight Sodium Dodecyl Sulphate (SDS) to the weight of the plasticizer is mixed to the molten state of the mixture of the bioplastic composition.
