Atofina has commercially introduced a new PP copolymer
made using single site catalyst and a special process. This copolymer
has melting point of 112°C, the lowest melting temperature observed
on commercially available copolymers so far. Interestingly, such
low melting temperature is attained at a reasonably lower ethylene
content of about 7%. This copolymer therefore will have high rigidity,
which is essential for form fill and seal operations and yet can
be sealed at lower temperatures. This new copolymer would boost
the heat sealing speed of PP film and would be very useful not only
for oriented film but also for T.Q. film.
PP film processors visiting K-2001 should definitely take the opportunity
to look at this new development.
