Trēva is a new BPA-free plastic containing 45% of cellulose-based plastic sourced from sustainably managed North American forests. Furthermore, because of its aesthetic, mechanical and chemical qualities it is an alternative that performs as well as acrylonitrile butadiene styrene (ABS).
“It is an ideal solution for cosmetics brands looking for sustainable solutions for opaque and colour-tinted packaging,” explains Cédric Perben, Global Cosmetic Technical Platform Leader, Specialty Plastics at Eastman. “Unlike other cellulosic material, Trēva achieves exceptional depth of colour and high gloss for opaque applications. Further assuring optimum aesthetics, its excellent chemical resistance to skin oils helps ensure packaging won’t crack, craze, become brittle, or discolour over the life of the cosmetics product.”
Trēva thus served as a basis for the development, in partnership with Groupe Rocher, of an eco-designed compact. Groupe Rocher shared their concept for a compact case simplifying processing into a single step instead of the typical three-step process. The design also eliminates the metal hinge pins and uses plastic pins instead.
“By eliminating metal and using fewer materials in the design, Groupe Rocher has created a compact case that requires fewer natural resources to produce, using less energy and eliminating secondary processing steps without compromising the packaging functionality and aesthetic brand codes,” states Stéphane Tétaud, packaging makeup development at Groupe Rocher. “This saves time and money during the manufacturing process and has the added benefit of taking a step toward recyclability.”
The compact lid is composed of the new Eastman Cristal™ EV600 copolyester, a glasslike high-flow polymer that is Cradle to Cradle Certified™ Bronze by the Cradle to Cradle Products Innovation Institute.
