Basell’s new family of resins specially developed for injection stretch blow-moulding (ISBM) applications offers new opportunities in food and household containers.
“These new resins are a clear alternative to glass and PET in a wide range of bottle applications,” said Mike Rogers, Basell’s innovation manager.
Stretchene resins represent a significant extension of the standard polypropylene property envelope in the direction of impact strength, rigidity and transparency.
“We’re aiming them at all kinds of ISBM applications from food containers to bottles for household chemicals and cosmetics,” Mike Rogers continued.
Hot fill
Stretchene resins are designed for high throughput on standard ISBM lines and the high transition temperature of Stretchene RP 1685 makes it a competitive candidate for hot-fill applications.
High transparency
High transparency is the special feature of resin Stretchene RP1903, making it suitable for cosmetic applications where excellent optical properties are required.
The low density (0.9 g/cm3) of Stretchene materials reduces packaging weight as well as cutting material costs by allowing more items to be moulded from a kilo of resin.
