OVER-MOULDING TECHNOLOGY CREATES INTRICATE PACKAGING FOR COSMETICS

An 'over-moulding' technology and has been developed jointly by Estée Lauder, its suppliers MBF Plastiques and SAF, and DuPont Cosmetic Solutions.
'This technology, which consists of a glass globe encased in DuPont Surlyn, combines the chemical inertness of glass with the total design freedom and practical benefits of our advanced polymer. These include durability (Surlyn is non-breakable and resistant to chips and marring) light weight and a pleasant sensual touch,' said Michel Decodts, Global Development Programme Manager, DuPont Cosmetic Solutions.
Numerous design options made possible by this development. 'Intricate shapes and decorative effects, such as sophisticated colours, metallic and fantasy coatings, frosted and unusual tactile properties - most of which would be impossible or extremely difficult to achieve in glass only are easily produced by over-moulding with Surlyn. Last but not least, there is the important advantage of cost-effectiveness,' said Decodts
The idea to over-mould glass came from Estée Lauder, which holds a patent on the concept. DuPont's European Technical Centre in Meyrin (Geneva), Switzerland, actively participated in the prototyping and commercial scale-up of this original concept and resolved one major technical challenge. That is to over-mould glass at high injection pressure and elevated temperature without breaking or displacing the (hollow) glass insert. Surlyn was the natural answer as it is extremely transparent and bonds easily to glass, making the bonding line almost invisible, even in thick-walled parts.
The first commercial applications of this over-moulding technology are an eyeliner and lip tint produced by MBF Plastiques of Oyonnax, France, for Estée Lauder. Both products were launched in the USA and Europe at the end of summer 2004.
