Sidel provides PET peroxide-resistant bottle system to hair care brand

Sidel has supplied Italian hair care company Farmavita with an EvoBlow stretch-blow-molding machine for on-site production of PET bottles. The system is designed to increase resistance to hydrogen peroxide-containing hair care products, which can become volatile during transport and degrade bottles. 

Manuel Ferrarotti, chief operating officer at Farmavita, says: “Our goal was to implement PET across products traditionally packaged in HDPE, paving the way for more sustainable solutions.”

“The products specifically selected contain hydrogen peroxide, which, under certain transport and storage conditions, can lead to an increase in 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.”

Sidel’s PET bottle base features a structured design that reduces collapse or deformation and “results in a more stable and appealing bottle on the line and the shelves.”

Before installing the blower at Farmavita’s plant, Sidel says it held dedicated packaging process sessions at their Packaging Excellence Centre in France to research the optimal blowing process and ensure top bottle performance.

“By partnering with leading packaging experts at Sidel, we were able to create a bespoke solution that addressed our coloured PET and material distribution requirements, resulting in a much higher quality bottle with an elevated ‘look and feel’ that our customers will appreciate,” says Ferrarotti.

The family-owned hair cosmetics manufacturer, Farmavita, aims to ensure that its hair care solution containers have the “ideal look and feel.”

Ferrarotti explains that the collaboration aims to lower the carbon footprint and energy consumption of Farmavita’s operations by leveraging PET’s lower blowing temperatures. 

Additionally, by developing in-house PET blow-molding capabilities, Farmavita aims to simplify its logistics and reduce packaging storage requirements.

Farmavita chose Sidel’s EvoBlow regular SBO 6 with a production output of 7200 bottles per hour in the 1 L format. Moreover, it customized the oven with two additional heating modules to increase the heating preform time while reducing the temperature.

According to Sidel, the process results in better material and stretching of the preform TIO2, which requires a longer heating time due to the white colorant. The additional ovens can also reduce ventilation requirements, resulting in a 10% decrease in energy consumption, says Sidel. 

The oven is equipped with an Air Recovery system that also reduces air consumption by 30%. 

Despite the additional ovens, Sidel explains that it optimized the machine layout by integrating a compact, customized preform feeder. This allowed the blower installation to fit within a tight space. Moreover, the infeed rail was also adapted to accommodate the very small preform neck ring.

Ferrarotti concludes: “In the future, we are considering integrating additional formats, such as 100 mL bottles, rather than relying on an external converter, which would also reduce our packaging and transport costs.”
