ENVIRONMENTAL REPORT
5.6 Products related aspects
Thin film, low density and multilayer technologies provide opportunities for packaging weight
reduction.
With a
density of 0.91 g/cm³
, polypropylene is among the
lightest polymers available in the
market
. This advantage, in combination with the low thickness achieved through biaxial orientation
technology, has been the key to success of BoPP films in recent years. However, there is still room
for improvement. If we look at packaging films, further benefits can be achieved in three directions,
where Taghleef Industries has always been involved:
Thickness

Carbon Footprint of Product
In 2010 we progressively extended our climate awareness by developing the
Carbon Footprint of Product
(CFP)
to all our products. This assessment is based on the LCA methodology and has been applied in a
cradle
to gate
approach, in order to produce figures that are useful for our
client needs.
The following table shows the global “cradle to gate”
CFP value per kg of product
and the splitted values
for raw materials, transport and production are included.

Thickness reduction
Typical thickness
for BoPP films is in the range of
30µm. Thinner films
, up to
15µm
, are available
for most specifications (transparent and metallised in particular) and offer plenty of opportunities for
packaging weight reduction without compromising on performance.
In cooperation
with
several top brands
, Taghleef Industries S.p.A. has demonstrated that
reducing
the thickness
of the package without compromising performance (appeal, runnability, shelf life) is
indeed possible. The table below, outlining the average thickness of a white voided film typically used
