production, the components of oil or natural gas are
heated in a cracking process, yielding hydrocarbon
monomers that are then chemically bond into
polymers. Some plastics contain other elements as
well such as Teflon containing fluorine, PVC
containing chlorine, and nylon containing nitrogen.
Plastic have vast applications in every prospect of life.
There are several reasons for the popularity of some
of them are follows:
 Low cost
 Resistance to chemical solar and microbial
degradation.
 Thermal and chemically insulating property.
 Low weight.
Plastics can be customised for numerous uses like
prosthetic limbs, bullet proof vest etc. The use of
plastic materials in cars and airplanes lessens their
weight arid hence upsurges their fuel efficiency.
Plastics are roughly classified into two main class.
These are explained in the table below which gives a
general overview of both the types.

MATERIAL AND METHOD:
a) Cornstarch
Cornstarch is employed to form the bioplastic
perishable. it additionally helps in correct composting
of bioplastic. Generally, cornstarch is insoluble in
cool water thus we tend to use H2O and vinegar to
disrupt the starch resolution in water of starch is five.9
to 7.5 that's lees 01, acidic or neutral.
b) Glycerine as a plasticiser
Plasticizers area unit usually little molecule like
polyols like sorbitol, alcohol and synthetic resin
glycol (PEG) that intersperse and add among and
between chemical compound chains, disrupting
atomic number 1 bonding and spreading the chains
apart, that not solely will increase flexibility, however

Thermoplastic starch (TPS) materials area unit

to modify melting below the decomposition

A.L.M. Smits, P.H. Kruiskamp, J.J.G. van Soest,
J.F.G. Vliegenthart, on heating starch freshly mixed
with plasticizers, a robust energy-releasing interaction

investigation. By Differential Scanning measuring
instrument (DSC). The transition physical property is
proportional to the amounts of alcohol or glycol
intercalary, suggesting that the plasticiser is
answerable for the discovered exothermic event.
However, specific interactions between plasticiser and
starch chains area unit tough to elucidate. it's usually
accepted that plasticizers lower the amount of
physical cross- links between starch chains, and
consequently retard the speed of retrogradation. The
method is irreversible, since reheating of the samples
showed no energy-releasing physical property peak.
Heat treatment provides rise to a robust starchplasticizer interaction, most likely caused by H-bond
formation. Plasticizers will be wonted to influence
this ageing induced by retrogradation. as an example,
in bread the degree of retrogradation is powerfully
reduced by the addition of monoglycerides, that act
with the at first amorphous amylopectin. Van Soest et
al. show. that associate increasing alcohol
concentration in a very waxy maize starch gel reduces
the speed of retrogradation. The inhibiting result of
assorted saccharides on retrogradation has
additionally repeatedly been reported.
c) Distilled Water:
Water is employed as a solvent to induce the
biopolymer (starch) into resolution. once the answer
heated, the water helps the starch molecules to
become no continuous and disordered (denatured).
When dried, the disordered chemical compound
chains become entangled and a neat film is created.
the method is named film-casting.
d) Vinegar:

RESULT AND DISCUSSION:
Acidic nature of the bioplastic must be due to the
vinegar in mixture because vinegar contain acetic
acid in it.

A. EFFECT OF PLASTICIZER

For further change in composition of raw material
(corn starch, vinegar, water) we get the
satisfactory result for 5ml and 10 ml of glycerine
composition.

Glycerine composition of 15ml and 20ml of
bioplastic films were very moist and it proved
difficult to dry them, so we rejected it.
Glycerine of 5ml composition were mostly perforated
film so that’s why we rejected it and we decide to go
further with 10ml of glycerine as a plasticize.

B. EFFECT OF pH:
 As shown in the above table, we observe the
sample of bioplastic to be acidic in nature.
 In preparation of bioplastic, as glycerine act as a
plasticizer, hence it does not make any major
change to the bioplastic mixture.

CONCLUSION:
By performing the project, we conclude that if we
increase the quality of glycerine (plasticizer) the
strength of bioplastic is decreased and perforations get
formed into the bioplastic and we cannot get dry thin
film. If we add glycerine as a plasticizer in accurate
and in small quantity then it is easy to make a thin
film and it is uniform film and if is also very easy to
dry. If we use very less amount of plasticizes in
appropriate quantity then the time required to make
the bioplastic is also less.
