Sidel StarLITE-R STILL rPET lightweight bottle base

The StarLITE-R STILL is Sidel’s high production speed 100% rPET bottle base for still products.

The bottle base uses Sidel’s patented technology for rPET integration, lightweighting and high-speed production for water, juices, milk and edible oil from 0.25 up to 2.5 L. It can also be retrofitted onto existing production lines and the solution requires a low blowing pressure.

Features include smooth material stretching and distribution, optimised venting for easy shaping and an efficient base cooling circuit suitable for rPET which is likely to be processed at higher temperatures.

Designed to ensure the base does not deform or break, the mould base’s rounded-edge design makes it easier to shape during blow moulding, which increases its resistance to defects such as bursts during the blowing process. This feature is particularly important for lightweight bottles, which are more prone to such issues due to the use of thinner material.

The bottle base is also compatible with a wide range of weights, including very lightweight bottles as low as 7 g for 500 mL format. It is easy to integrate onto existing manufacturing lines and is qualified for high production speeds across various bottle formats.

It supports single-serve production rates of up to 2700 bottles per hour per mould and multi-serve rates of up to 2400 bottles per hour per mould. The bottle base can also be used with virgin PET.
