PE coated paper / (Single
Side Laminated Paper )is a paper that is coated with
PE or polyethylene. Polyethylene (or polythene) is the
name of the most widely used plastic around the globe.
The reason for coating any paper, with a compound (in
this case polyethylene), is to impart some desirable
qualities, of the latter, to the former.
Polyethylene basically has a very high
resistance to chemicals and does not dissolve at room
temperature. Another great property of this plastic,
which is also responsible for its high demand, is its
resistance to water. However, a major reason, why
despite these qualities its use is facing opposition is
the fact that plastics take several centuries to
de-grade; unless exposed to UV-rays.
PE coated paper
has thus been an answer to the requirement of these
qualities in the packaging industry; addressing the
environmental issues, alongside. PE coating not only
renders the paper water resistance, but confers it wet
strength as well. The latter here refers to the strength
with which the fibre-web of paper holds together,
against a force of rupture.
A Pe coated paper is made by a
process known as extrusion coating. In this process, a
coating of plastic, in its molten state, is extruded
onto the paper; through a slit dye, at temperature
touching 320˚C. Following this, it passes through a nip,
holding a rubber-covered pressure roller. Finally, a
trip through the chrome-plated cooling roll, cools it
back into solid state, and imparts the plastic surface,
the desired finish.
The demand of the pe coated paper
is majorly witnessed throughout the packaging industry.
This pe coated paper may be bleached pe coated
paper; pe coated silk paper; or natural coated
triplex boards. This
Paper is used in

The bleached PE coated paper
finds its uses in the food and pharmaceutical field; for
wrapping/packaging of meat, cheese, pastries, cakes,
butter, sugar, spices as well as for powdered medicines.
The silk paper is mainly used in the textile industry
for wrapping fabrics. The unbleached or natural
coated paper is used in construction as well as
paper and wood processing industries; for
wrapping/packing of timber, construction supplies, paper
The pe coated paper may be
single PE coated or double PE coated. As in the case of
paper cups, the hot ones are coated only on the inside,
i.e. single PE coated. The hot ones, on the other hand
are coated on both the inside as well as outside. This
is so as to prevent the condensed moisture from soaking
in; which might make the cup lose its rigidity and
become soggy. This PE coat not only water-proofs the
cup, but also allows the seams to weld together.
Owing to their property to the keep the inside (and
outside) moisture and flavor inside (and outside); these
pe coated papers are also widely used in the liquid
packaging industry. Juices, milks and a number of other
beverages are packaged in cartons made of this material.
They find other uses as inner lining of cartons, heat
sealable wrappers or labels etc also.
