Polystyrene plastics for beverage bottles an inexpensive alternative Plastics beverage bottles manufacturer ALPLA along with BASF's impact resistant polystyrene result in a packaging alternative for milk and yoghurt.
Right in time for the K 2007, BASF joined forces with ALPLA, one of the
world’s largest manufacturer of plastics beverage bottles, to come up
with a bottle for milk and yoghurt beverages using impact resistant Polystyrene
(PS-I) a high-impact polystyrene plastics. This demonstrates that Polystyrene
is an inexpensive plastics alternative when it comes to packaging for
this sector. BASF’s Polystyrene type BX 3580 – specially optimized for this application – can be processed by injection blow molding and injection stretch blow molding on the same machines used for PET. The advantage for packaging manufacturers is that the lower density of Polystyrene in comparison to PET can slash material costs by up to 25%. Even more energy and money are saved because injection stretch blow molding uses less compressed air and, unlike PET, the Polystyrene does not have to be pre-dried. “We have filed a patent application for this process and will continue to be involved in this realm,” explains Jaroslaw Michniuk, head of marketing for standard styrenics at BASF in Ludwigshafen.

Visitors of the K Show 2007 enjoyed a vitamin-enriched milk beverage from
the first milk bottle made of polystyrene. BASF supplies standard and impact-resistant grades of polystyrene for
use in injection molding and extrusion, coextrusion, thermoforming, blow
molding, and injection blow molding. As a global player, BASF has further
expanded its technological competence in polystyrene. World-scale production
facilities supply the most important markets with products having a consistent
quality. In packaging for food products, in office and information technology
or in refrigerators – all sectors make high demands of the combined properties
of the materials used. In its diverse variants, polystyrene offers extraordinary
property combinations, thus making a vital contribution to everyday life.
At the K 2007, BASF showcased its first Polystyrene milk bottle along
with Styrolux* HS 70, the new plastics used for the production of shrink
films. This very transparent SB polymer has a high maximum shrinkage as
well as excellent processing properties, so that films made of this material
can easily wrap even odd-shaped articles. Got a Cool Job in Plastics Packaging?- Our Dedicated Portal Helps U- $ave See all the Press Releases from BASF sites. Read a recent article about -
