MOULD MAKING PETplanet Insider Vol. 26 No. 04/25 www.petpla.net 34 MOULD MAKING 34 100% rPET lightweight bottle base for still products StarLite-R Still is a new bottle base that employs Sidel’s patented technology to ensure 100% recycled PET (rPET) integration, lightweighting, and high-speed production for water, juices, milk, and edible oil from 0.25 l up to 2.5 l. Balancing production speed, material type, and bottle weight presents a complex challenge for manufacturers in maintaining high performance. According to Sidel the StarLite-R Still overcomes these with precise bottle base shaping and efficient material distribution. Its design can be seamlessly retrofitted onto existing production lines ensuring versatility and the solution requires low blowing pressure, further enhancing its sustainability credentials. High performance The StarLite-R Still bottle base features Sidel’s patented technology which includes smooth materialstretching and precise distribution; optimised venting for easy shaping; and a base cooling circuit ideal for rPET which is likely to be processed at higher temperatures. According to Sidel, the new design ensures that the base does not deform or break, crucial for maintaining the bottle’s integrity during production, conveying, storage, transportation, and use. The mould base’s rounded-edge design makes it easier to shape during blow moulding, which increases the bottle base 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. With a high base clearance, structural design prevents deformation, ensuring functionality and stability even in high-temperature conditions. The bottle base performs during high-speed production, thanks to efficient cooling. This cooling process prevents deformation and defects, maintaining consistent quality at rapid manufacturing speeds. The bottle production process can use up to 20% less blowing pressure due to improved mould venting of the StarLite-R Still mould base. The carefully designed grooves and venting holes in the mould are claimed to ensure that air escapes smoothly, allowing the bottle base to take its desired shape at lower pres- ?
