LDPE Low Density Polyethylene
LDPE Raw Material
LDPE Raw Material(low density polyethylene) is a soft,
flexible, lightweight plastic material. LDPE is noted for its
low temperature flexibility, toughness, and corrosion
resistance. It is not suited for applications where stiffness,
high temperature resistance and structural strength are
required. LDPE is often used for orthotics and prosthetics. It
has good chemical and impact resistance and is easy to
fabricate and form. LDPE Raw Material has an excellent
resistance to acids, bases and vegetable oils. Its toughness,
flexibility and relative transparency make it good for
packaging applications requiring heat-sealing.
LDPE Raw Material is used to make many thin, flexible products
like plastic bags for dry-cleaning, newspapers, bread, frozen
foods, fresh produce and garbage. Most shrink-wrap and stretch
film is also made out of LDPE, as well as coatings for paper
milk cartons and disposable beverage cups. Manufacturers also
use LDPE to create thin container lids, squeezable bottles and
some toys.

Applications Of LDPE Raw Material:
LDPE Raw Material is principally used for making films. It is
widely used in the production of agricultural film (mulching
film and shed film),packaging film (for use in packing candies,
vegetables and frozen food), blown film for packaging liquid
(for use in packaging milk,soy sauce, juice, bean curds and soy
milk), heavy-duty packaging bags, shrinkage packaging film,
elastic film, lining film, building-use film, general-purpose
industrial packaging film and food bags. LDPE Raw Material is
also widely used in the production of wire & cable
insulation sheath. Cross-linked LDPE is the main material used
in the insulation layer of high-voltage cables. LDPE is also
used in the production of injection-molded products (such as
artificial flowers, medical instruments, medicine and food
packaging material) and extrusion-molded tubes, plates, wire
& cable coatings and profiled plastic products. LDPE Raw
Material is also used for making blow-molded hollow products
such as containers for holding food, medicine, cosmetics and
chemical products, and tanks.

Recycling LDPE Raw Material
LDPE is an easily recyclable material and is collected by many
recycling programs in most area. For recycling purposes,
this material is identified by the resin ID code '4'. However,
the different forms of LDPE packaging (i.e. film and bag vs.
rigid), require different recycling channels. Rigid LDPE
products such as bottles, containers, caps and lids are
typically accepted through your traditional curbside recycling
program. Flexible LDPE products, however, can be dropped off at
participating retail stores in your area. Plastic Film
Recycling, an organization supported by the Flexible Film
Recycling Group of the American Chemistry Council, has put
together a handy tool that allows you to locate local drop-off
centers where you can recycle your clean and dry flexible LDPE
products. Acceptable flexible LDPE materials include retail
bags, zip-top food storage bags, plastic overwrap, and even
plastic cereal box liners.

What is the Difference Between LDPE and HDPE?
LDPE and its sister plastic, HDPE, are two of the most common
types of plastic on the market. They have a lot in common, and
a lot that separates them too.
Some of the similarities between the two are that they both
have low material weight and high impact strength. They are
also both highly recyclable, which is one of the most
attractive features of LDPE and HDPE. The fact that they can
practically be used again and again and then converted into
useful and new products after being discarded is a huge plus
for businesses and the environment.
Both LDPE and HDPE are also cheap to make and have a low cost
of manufacture and fabrication.
There are differences that set them apart too, though. For
example, LDPE is much softer and more flexible than HDPE. It
also has a lower melting point and is more transparent too.
That means that LDPE is more prone to cracking under pressure
and stress.
On the flip side of that, HDPE is more rigid and durable and is
better at chemical resistance. It has a higher melting point
and can withstand more brutal temperatures than LDPE.
While both LDPE and HDPE are recyclable, they cannot be
recycled together. LDPE is classified under recycling number 4,
and HDPE is recycling number 2. LDPE can be more difficult to
recycle as it is softer and can get caught up in the machinery
needed. Meanwhile, HDPE (often milk and juice cartons and other
food containers) is easier to transport.
When it comes to molding and shaping stronger and more durable
products, HDPE is much more useful and reliable than LDPE.
Between both HDPE and LDPE, these two types of plastics have
all sorts of industries covered - quite literally. With HDPE,
they are able to transport and package materials, while LDPE is
able to cover and coat and keep many perishables safe.
Without HDPE and LDPE, all sorts of foods and other precious
items would be lost.
LDPE is a very special type of plastic that is something many
people take for granted. You will remember the usefulness of
LDPE the next time you wrap up some food that you want to enjoy
again later.While there are a few disadvantages to LDPE
plastics, the good far outweighs the bad with this unique
creation that is used all over the world and throughout nearly
every business. It is a low-cost, low-energy and
environmentally-friendly product that creates a stronger shelf
life for so many goods and makes life much, much easier for
everyone.
