'Lightest, half-litre polystyrene bottle in the world' - BASF

摘要

An innovation project has paved the way to BASF's success in using a conventional stretch blow-moulding machine to create the lightest half-litre polystyrene bottle ever - it weighs a mere 7,5g.rn'This project gave BASF the opportunity to discover how lightweight bottles for dairy products can be made of polystyrene using stretch blow-moulding methods. Less weight always translates into lower costs and less consumption of resources,' says a company spokesperson.rnSince polystyrene has a lower density than PET, it can be used tornproduce bottles that weigh less, but have the same wall thickness. 'Owing to the special properties of this plastic, BASF recommends the new polystyrene type (PS BX 3580) specifically for containers used for milk products,' he says. "This is an approach that will be pursued consistently together with customers'
