LyondellBasell launches PET-alternative for cosmetics packaging

LyondellBasell Industries is launching a new polypropylene-based, high-clarity copolymer for potential use in extrusion and injection blow moulding applications that require glass-like clarity.

High level of transparency

The Rotterdam-based polymers producer has developed a new resin that could be a valuable alternative to PET-based cosmetics packaging. According to LyondellBasell, the Metocene RM2231 resin combines excellent transparency with the typical attributes of polypropylene-based copolymers, such as flowability, thermal and impact resistance, and recyclability.

According to LyondellBasell, the new resin can be considered as a replacement for amorphous and transparent polymers used in cosmetics applications, which are traditionally the domain of injection blow moulded PET.

We were able to combine the clarity and gloss of PET with the density and recyclability advantages of polypropylene,” claims Bernd Schütz, marketing manager for Metocene resins at LyondellBasell.

Time and energy savings

LyondellBasell also argues that its new resin is a more cost-effective solution than PET for applications produced using injection blow moulded technology.

The Metocene RM2231 resin does not require pre-drying and the high processing temperatures associated with other resins such as PET, thus allowing converters to “save time and energy costs, thereby improving the overall economics of the process,” claims the company.

On center stage, the floral bouquet is making its come back

Just like fashion that is eternally being reinvented, perfumery also works in cycles. And the floral accord is no exception. The very essence of femininity, today floral fragrances are less invasive than in the 1980s, as was the case with Poison by Christian Dior. At the end of the 1990s, floral accords were replaced by clean musky (...)
