=====: PLA Introduction
:=====
|
|
What is
PLA.
PLA stands for Polylactide Acid, and it’s a versatile polymer
produced from 100% corn or other
annually renewable plants which
contains starch by NatureWorks® LLC. PLA is made from lactic
acid. Lactic acid is made from dextrose by fermentation. Dextrose
is made from cornstarch and
cornstarch is made from carbon dioxide
and water.

Features
of PLA.
-
It’s
biodegradable, recyclable, and compostable.
-
It
does not
cause or release any toxicity, toxic gas and nor any
environmental pollution when it is
incinerated.
-
It’s
similar to traditional plastic in
characteristics, physical
& mechanical properties without changing user’s habit
for plastic products.
-
It
has good ventilation,
permeability, tensile strength and anti-static.
-
It
has very good
stiffness and rigidity.
-
It
has good oil and grease
resistance.
-
It
has flavor and aroma barrier.
-
It
can degrade in 47 days, depending on specification and natural
conditions.

Benefits
of PLA.
-
Uses 20 - 50% less fossil fuels compared to traditional petroleum
based
plastics.
-
Reducing
greenhouse gases and smog in our
atmosphere.
-
Reduces
burden on landfill.
-
Excellent
flavor retention & aroma barrier keeps food tasting and
smelling fresh longer.
-
Versatile:
Replaces
many traditional packaging alternatives for a broad
range of applications.
-
Clear: Excellent clarity and high gloss provides ideal product
display on shelves.
-
Strong and Durable:
Protects your product appearance while
guarding against spoilage.
-
Printable: Graphic imprint to present your design and message.
-
Secure: Self-seals rapidly with heat, also compatible with
a
wide range of adhesive technologies.
-
It has excellent resistance
to most oils and fats, which are
used in food preparation.
-
Cleaner production process and thus reduced harmful pollutants
emitted into the
air.

Certifications
of PLA Biodegradability.
The
biodegradability of our materials has been measured according
to standard test methods approved by International Organizations
(ISO, CEN, ASTM, DIN) and the
compostability is certified by the
“OK Compost” label by OWS (ORGANIC Waste System),
Belgium and “Din Certco” by Din Certco” by DIN
(Deutsche Industrielle
Normalische), Germany.

Life
Cycle of PLA.
PLA
is
fully compostable and it can be disposed of by all traditional
waste management methods such as
incineration, landfill and
mechanical recycling.
In
the soil or water, microbes convert the
product into water and
carbon dioxide, and then green plants take them in through the
process known as photosynthesis, converting once again to starch.

| Summary.
Conventional
plastics materials have brought convenience to our everyday life
for many decades, however these conveniences have come at a grave
cost to our environment in
ways of pollution, toxic emissions and
a depletion of our natural resources. We are feeling some of the
consequences today from them, but much more will be left for our
future generations to
deal with if we don’t look for alternatives
for the future now. However today we have a new solution
in PLA,
which is a very innovative and biodegradable material, which can
be used for
making packaging products for food with consideration
for our ever concerning environment and for the
future generations.
