SURLYN®: THE MAGIC OF SHAPES AND COLOURS FOR THE HAPPYLOGY BEAUTY CREAM JAR
31 October 2003 - DuPont Engineering Polymers
| Happylogy, a beauty cream belonging to Guerlain’s anti-age product line, comes in a superb pearly blue, softly-shaped jar, made from DuPont™ Surlyn® PC 2000.

Moulding this part was a real technical challenge for several reasons. First of all, as the jar has an irregular spherical shape, the walls vary significantly in thickness and reach up to 20 mm in some areas. Next, the injection gate has to be as unobtrusive – and therefore as small – as possible. Finally, despite its irregularities, the jar has to retain both its transparency – as this is how the iridescent aspect of the cup is transmitted – and the regularity of its translucent blue colour. Risdon AMS has overcome all these difficulties, thanks to a combination of the company’s expertise and the performance of Surlyn® PC 2000. Initially, the use of different materials were considered, but Surlyn® ionomer resin was the final choice: not only it provides shine, but it also has the advantage of withstanding forced demoulding. A subsidiary of packaging giant Crown Cork & Seal, Risdon AMS is specialised in manufacturing and selling plastic parts for the cosmetic industry and employs about 400 people.
