SteadyEDGE™ is a unique, patented bottle base solution that offers food, home and personal care (FHPC) producers new opportunities for brand differentiation. Sidel's new BOSS (Base Over Stroke System) solution is easy to implement and retrofit and is compatible with Sidel's universal blow-moulding machines.
The new base technology overcomes the challenges of producing flat, oval and rectangular PET containers, which require a specific production process with optimised PET material distribution in order to produce high-quality packaging.
„SteadyEDGE enables the production of high-quality PET containers with sharper edges whose diameter can be reduced to just one millimetre instead of the previous 2.5 millimetres,“ explains Pierrick Protais, Head of Packaging Innovations at Sidel. These edges increase the Freedom of design and simplify production more elegant container with less rounded bases. They also open up special marketing opportunities for containers with complex shapes and large surfaces for the Labelling.
The innovative packaging solution optimises productivity, reduces total cost of ownership and maintains high product quality and reliability. Its benefits also include a potential weight reduction of up to ten per cent by improving the stretching of the material for the base. The reduced blowing pressure lowers energy consumption during production by up to 20 per cent.
Intelligent blow moulding process
The specific design of the „sharp edge“ is realised with the new, patented Sidel moulding system for soils. BOSS is a piston that is activated during the blowing phase to move the base. This mechanical element enables the base to be raised and lowered during bottle moulding independently of the opening and closing of the two half-shells of the mould. A BOSS/BOSS mould changeover only takes three minutes, a changeover between BOSS and another mould eleven minutes.
