New base solution to increase the stability of flat PET and rPET containers

Date: 05.05.2021Source: Sidel

Sidel is introducing the StarLITE HPC base, the new oval bottle base alternative for flat PET containers that helps achieve optimum performance and can also comply with recycled PET (rPET) up to 100%. The new bottle base not only increases container stability by up to 25%, but also optimises bottle weight and energy consumption, reducing production costs and greenhouse gas (GHG) emissions with a quick payback.

The new geometry of the completely flat StarLITE HPC base is cleverly structured. Its new anti-rocking design is based on a 360-degree continuous contact surface which improves tilt angle and may be combined with structural ribs and oval push-up.

Explains Laurent Naveau, Packaging expert at Sidel: “The doubled sitting surface and the balanced stretching ratios between small and large sides enable better material distribution, while avoiding base sagging.” 

This oval shape achieves an optimum performance level, drastically improving empty or filled container stability by up to 25%. This helps increase production uptime, with better container stability on conveyors in comparison with existing major flat PET container bases, and also improves consumer experience.

Applicable for both opaque and transparent PET resins, the StarLITE HPC base offers wide containers opportunities and is perfectly compliant with rPET up to 100%. The smart, asymmetric, structured base design improves material distribution, prevents unexpected base roll-out and contributes to lightweighting opportunities, i.e., a 0.5 g PET reduction for a 500 mL container base. The enhanced base cooling engineering for mould and tooling design improves base cooling during blow moulding and may prevent post-mould base cooling according to bottle shape, format and weight.

This StarLITE HPC is compatible with all generations of Sidel blow moulding machines: SBO EvoBLOW, SBO Universal, SBO Series2 and SBO Series1. For more visit sidel.com
