Polypropylene is a Challenge Polypropylene is already the preferred choice for many packag-

for heat-setting.

The major limitation of using PP as a packaging material

is its lack of transparency.PP is a semicrystalline material

with natural haze and is less transparent than polyeth-

ylene terephthalate (PET) and polycarbonate (PC), or

glass.Technological developments are improving the

appearance of polypropylene but challenges remain.

New additives called clarifying agents have been intro-

duced to be incorporated in random copolymers of PP to

achieve the desired clarity, haze reduction, easy disper-

sion of clarifying agents.

Clarizol is a sorbitol based clarifier that meets all the

requirements of the polypropylene industry: clarity,

grades, shows no signs of chemical degradation and

does not affect the organoleptics of the finished article.

As a clarifier, Clarizol imparts low haze, as well as main-

tains an excellent impact stiffness balance. These proper-

ties are extremely important in thin walled applications

such as yoghurt containers and food containers.
