The French luxury brand has entrusted Texen with the transition to PET of the compact case of its Le Blanc foundation, one of its iconic references. The choice of this complex material represented a strategic step for the brand and a new challenge for Texen.
From ABS to PET
Until now, this large, refillable compact was crafted from ABS, it is now made entirely from PET (with the exception of the pin and mirror). With this strategic choice, the brand is anticipating changes in European legislation on cosmetic materials and pursuing its quest for eco-design.
Chanel chose to switch its packaging to PET, all the while maintaining their rigorous technical and esthetical requirements.
Another recent development, the big-sized compact for Les Beiges, involved a number of challenges for Texen because of its large size and injected thin walls in rPET. This time, Chanel opted for PET and not rPET for reasons of colour stability, given the compact’s pale shades. “This latest development demonstrates the numerous challenges imposed by the transformation and decoration of a new material,” said Texen in a statement.
Texen drew on the experience gained during the development of the previous compact to better industrial processes with the design, but also to challenge its partner suppliers.
The complex injection of PET was a big challenge, which required multiple test runs, in particular for the lid, with a top and edges in different shades.
To inject the edges, Texen used the “Besst Transform” induction technique based on Roctool’s engineering . “The part has perfect aesthetics without any surface flaws,” highlights Texen.
The brand’s logo is then applied to the center of the lid using hot stamping. Each part was injected then decorated in-line with a high-solid varnish.
The final assembly was performed on a production line equipped with an onboard “zero defect” inspection module for each and every part. The lid and hinge are joined with a pin compatible with the mechanical properties of the material. Inside, the pan is clipped into the well, allowing the consumer to easily replace it with a new refill.
