Overmolding of Linkx® Bottles from Bormioli Luigi
At the PCD (Perfumes, Cosmetics and Design) exhibit in February 2012, visitors to the DuPont booth saw a vast array of forms, textures and optical effects for the packaging of perfumes and cosmetics that are only possible by the innovative use of DuPont™ Surlyn®. One such concept that was presented at the show by the Italian glassmaker Bormioli Luigi SpA, was the overmolding of glass bottles with Surlyn® 3D technology. The new products, marketed by Bormioli Luigi under its Linkx® trademark (http://www.bormioliluigi.com/perfumes/), was also the subject of a conference that was held during the PCD exhibition entitled "New opportunities in bottles design by Linkx®."
The latest bottle concept from Bormioli Luigi SpA has been designed by French luxury design specialist QSLD. The twisted shape of the glass inner bottle is accentuated in perfect transparency by the thick walls of the cube, made with DuPont™ Surlyn®, that encases it. QSLD further emphasizes the contrasts shapes made possible by the overmolding technology in its choice of colors, as Christophe Guichard, QSLD President, explains: "The choice of charcoal grey for the Surlyn® outerlayer was obvious for the mood and type of design we wanted to create, and we found gold to be the best colour to enhance this smoky effect. One of the amazing possibilities of Surlyn® 3D technology is the ability to create two contrasting shapes, each of them decorated differently. This creates double the surprise!"
The successful overmolding of a glass bottle using Surlyn® 3D technology is the result of collaboration between Bormioli Luigi, DuPont and the Italian injection molding specialist Pibiplast SpA. Bormioli Luigi's patented Sparkx® glass formulation is stronger and more durable than ordinary glass and is also particularly clear in its appearance. Its properties also make it suitable for subsequent overmoulding (either entirely or partially) with Surlyn® using a unique process mastered by Pibiplast. The spectacular end result is a bottle that is almost limitless in terms of the colours and shapes adopted for both materials and also the finish of both the internal and external
“As illustrated by our latest concept, Linkx® gives free reign to one’s imagination in terms of shapes and colours and optical effects for the bottles,” claims Corrado Lusetti, marketing manager at Bormioli Luigi. “The glass provides high resistance to chemicals and alcohol and a luxurious sense of weight, whilst the shell made of Surlyn® can be used to magnify, enhance and durably protect the visual effect of the bottle, as well as rendering it far less susceptible to breakage or damage. At the same time, the material's favorable tactile properties make the bottle both smooth and pleasant to the touch. ”
