Yves Saint Laurent’s new All Hours foundation promises full coverage and staying power with a luminous matt finish without caking. Mirroring that of the Libre fragrance, its packaging sports a new design with the YSL logo as its standout feature.

The Yves Saint Laurent logo enlaces the cap like a vine, a decorative feature which, when added to the technical challenge of a manufacturing a lid made with recycled content, demanded both audacity on the technical front and industrial maturity on the part of Texen’s teams.

RPET and rheology

In line with the brand’s expectations and its environmental commitments, which Texen shares, the project involved adopting new-generation materials. Texen pushed the boundaries of its industrial capabilities with a dual challenge: esthetic imperatives and the use of RPET.

The cap is a single part thanks to in-mould engraving of the logo, for which the thickness of the relief added complexity.

In order to optimize the conception of industrial tooling, Texen’s teams relied on rheological research. As such, the experts were able to perfect the various injection parameters, anticipating the performance of the material to avoid gluing lines so the moulded part would be completely uniform. “This expertise perfected over time offers a major advantage when product specifications are both technical and esthetic,” said Texen in a statement.

The second complex operation was the decoration of the cap and the hot-stamping of the décor in a single pass.

This technically complex product and the use of recycled material required close collaboration between Texen’s technical and development teams at the service of the brand,” concludes the company.
