Sidel goes for a world record with hot fill design
24/11/2009
Line speeds of up to 1,800 bottles an hour per mould are available with a standard HR process
Sidel has launched what the company describes as ‘world record’ beating hot-fill PET bottles. The lightweighted designs – Skyward and Curvy – weigh less than 19 grams for a 0.5ltr bottle. The lightweighting has been made possible by a redesign of the neck, body and base, according to Sidel. The 28mm amorphous (non-crystallised) neck has been made lighter but accepts a standard cap for carbonated soft drinks. The base has also been revised, making it stiffer while also using less material. The revised geometric structure of the bottle body compensates for deformations due to vacuum absorption after cooling, claimed the manufacturer. The Skyward bottle has a square section over a cylindrical one, an “anti-ovalisation” waist and a rigid label area at the base. The rigidity of the Curvy bottle is obtained using a similar construction with the twisted shape acting as support while the curves also make the bottle easier to grip.
