(Plastics Today) -- Netstal is
aiming to chip away at Tetra Pak's dominance of the Brazilian dairy market, with
plans to install its two-layer polyethylene terephthalate (PET) preform
technology in the South American country by the end of the year.
There are some blowmolded plastic bottles for dairy currently on the
market in Brazil, according to Zavaglia, but they utilize a label across the
entire container to protect the milk from UV light exposure. Netstal's system
first injects an opaque, black core, which is then overmolded with a white PET,
creating a fully UV-protected container that doesn't require a complete
sleeve.
This will be the first time this technology is deployed in Brazil, with
the only other system in the world running in France. The 24-cavity mold
actually utilizes 48 cores, with one set in white and the other in black. The
black preform is injected first, and then the mold opens, the cores move, and
white is overmolded. Zavaglia conceded that Tetra Pak is the runaway market
leader but said even chipping away a few customers would be a huge victory for
Netstal.
