With thirty years of experience creating high quality professional hair products from its full cycle industrial complex near Milan, family-owned hair cosmetics manufacturer, Farmavita, dedicates its full effort to ensure that their containers have the ideal look and feel.
Now operating in forty countries, Farmavita chose Sidel’s EvoBLOW solution to maximise the integrity and quality of its 1L white PET bottles within the limited space constraints of its existing manufacturing line.
Manuel Ferrarotti, Chief Operating Officer at Farmavita, commented: “Our goal was to implement PET across a wide range of products traditionally packaged in HDPE, paving the way for more sustainable solutions. By leveraging PET’s lower blowing temperatures, we aimed to lower both our carbon footprint and energy consumption. Additionally, by developing in-house PET blow moulding capabilities, we wanted to simplify our logistics, reduce packaging storage needs, and improve overall operational efficiency.”
“The products specifically selected contain hydrogen peroxide, which, under certain transport and storage conditions, can lead to an increase of the internal pressure and deform the base of standard HDPE bottles. The look and feel of our packaging isn’t just important – it’s essential to how customers experience our brand.”
Addressing colour requirement and material distribution
To create a clean, impactful look and feel for its 1L bottles that remains consistent from production through to store shelves, Farmavita uses preforms with TIO2 white colourant – a food additive valued for its colouring and opacifying properties.
This leads to two significant challenges in the manufacturing process. Firstly, the TIO2 additive makes the preform harder to blow, requiring more heating time. Secondly, the bottle must have equal resistance across its whole surface, especially at the base, to withstand the internal pressure due to the potential reactions of hydrogen peroxide that can occur due to high summer temperatures.
