The document discusses the history and properties of plastics. It notes that plastic is a synthetic or semi-synthetic material that can be molded into different shapes and is typically made from polymers. The first man-made plastic was Parkesine, invented by Alexander Parkes in 1856. Parkesine was made from cellulose treated with nitric acid to create cellulose nitrate, which could be molded when heated. The document focuses on how plastics were used in packaging and toys and the environmental impact of plastic waste.

2.  Plastic is a material consisting of any of a wide
range of synthetic or semisynthetic organics that
are malleable and can bemolded into solid objects
of diverse shapes.
 Plastics are typically organic polymers of
high molecular mass, but they often contain other
substances. They are usually synthetic, most
commonly derived from petrochemicals, but many
are partially natural.
 Plasticity is the general property of all materials that
are able to irreversibly deform without breaking, but
this occurs to such a degree with this class of
moldable polymers that their name is an emphasis
on this ability.

3. Parkesine is considered the
first man-made plastic. The
plastic material was patented
by Alexander Parkes,
In Birmingham, UK in 1856.
It was unveiled at the 1862
Great International
Exhibition in London.
Parkesine won a bronze
medal at the 1862 World's
fair in London.

4. Parkesine was made
from cellulose (the major
component of plant cell walls)
treated with nitric acid as a
solvent. The output of the
process (commonly known as
cellulose nitrate or pyroxylin)
could be dissolved
in alcohol and hardened into a
transparent and elastic
material that could be molded
when heated. By incorporating
pigments into the product, it
could be made to
resemble ivory.

of us are used over
and over again, not
