New PET bottle designs from Sidel offers a competitive advantage for liquid dairy manufacturers, and are also suitable for applications within the juice, nectar, soft drinks, isotonics and tea sector.
This mini-size PET bottle has been designed for products such as drinking and probiotic yoghurts with capacities between 65ml to 150ml and is ideally suited for ambient and cold chain processes.
Sidel packaging innovator leader Laurent Naveau said the format had been launched to support the liquid dairy product industry where the use of PET packaging has increasingly become an ‘attractive alternative’.
“Part of Sidel’s continuous packaging optimisation programme, this bottle is designed to reduce greenhouse gas emissions and costs while also offering new marketing opportunities and high production performance for manufacturers,” said Naveau.
Sustainability and cost efficiency
Sidel said manufacturers could benefit from PET’s heightened sustainability credentials as the only food grade bottle-to-bottle recycled plastic.
By switching to PET, manufacturers can achieve up to a 40 percent cost reduction when moving from polystyrene to PET and a 20 percent reduction from HDPE (high density polyethylene).
“Our new size has the best-in-class bottle weight with just 3.9g for a 100ml extended shelf-life bottle and 5.4g for 100ml aseptic bottle achieved through a dedicated preform design.
“This new preform design is qualified for 100 per cent rPET content and also enables a low blowing pressure below 15 bars. The mini-bottle guarantees producers total product integrity while also offering compatibility with a range of safe, convenient capping solutions,” said Naveau.
High performance
Sidel’s new ultra-small bottle is based on a uniquely designed preform, which ensures a wide process window even with reduced heating zones. This offers optimum material distribution guaranteeing a high- bottle performance.
“Sidel’s packaging experts developed a preform that achieves great bottle quality. The accurate material distribution on the bottle ensures that its performance is secured even with lower blowing pressure and a reduced quantity of material. We’re excited to work with producers within the liquid dairy product sector to realise the full scope of our new ultra-small and light design range,” said Naveau.
Complete line solutions
Sidel offers a complete line solution for liquid dairy and sensitive products, building on over 40 years of experience operating within and supporting manufacturers in this industry.
The new bottle size is compatible with the company’s Aseptic Combi Predis FMa - the market’s simplest and fastest aseptic solution with dry preform decontamination. It offers a safe, hygienic and cost-effective way of packaging sensitive products to ensure high-end taste and long shelf life with minimal water and chemical usage.
Similarly, the bottle is also suitable for high production speeds with up to 66,000 bottles per hour.
