Sidel SteadyEDGE sharp-edged PET container bases
Sidel’s SteadyEDGE technology is used to produce flat, oval and rectangular container base designs in PET.
The specific sharp base design — which can have a radius as little as only 1 mm, compared to a previous minimum of 2.5 mm — is achieved using the Base OverStroke System (BOSS). BOSS is piston activated in the blowing phase to stroke the base. This mechanical element allows for the raising and lowering of the base during the bottle-forming process independent of the opening and closing of the two half-shells of the mould.
BOSS provides the option to implement quick mould changeovers to ensure maximum production uptime. Easy to implement and to retrofit, Sidel’s BOSS solution is fully compatible with Sidel Universal blowing machines.
The packaging solution improves productivity and low total cost of ownership (TCO). Benefits include lightweighting possibilities of up to 10% through the improved material stretch on the base. A reduction in blowing pressure decreases energy consumption by up to 20% during production when limitation is linked to base design.
The sharper edges aid design freedom and facilitate the production of more elegant containers with bases which are less curved.
The sharper edges possible on the package are used to effectively flatten and increase the ‘standing ring’ area of the base. The application of SteadyEDGE to any design can enhance the package’s stability by as much as 35%. This is beneficial on the supermarket shelf, in the home and on the production line. As packages are less likely to fall while they are being conveyed between various machines, this results in fewer stoppages and improved uptime.
