Yili launches Ambrosial Greek yoghurt with dry aseptic PET lines from Sidel
China’s leading dairy brand, Yili,strives to provide Chinese consumers with high-quality, nutritional, healthy, and innovative dairy products. Their continuously growing sales demonstrate how they manage to be successful in differentiating their brand with the help of premium dairies.
A strong believer in the potential of PET as a packaging material, Yili is launching its Ambrosial greek yoghurt line in PET single serve bottles, investing in three Sidel aseptic complete PET packaging lines, including the Aseptic Combi Predis with its dry preform sterilisation technology.
The new lines signal a partial switch from carton to PET. Yili said that it perfectly matches the Chinese consumers’ expectations by being user-friendly, shatterproof, re-sealable, and recyclable. It also provides freedom in bottle design to differentiate their dairy brand on the Chinese supermarket shelves.
PET also offers great benefits in terms of physical product and food barrier protection, therefore preserving nutritional and sensorial properties of yogurts at all stages – from production, storage, and shipment to distribution. In addition, the closure tightness adds to PET’s convenience even without the use of aluminium foil.
5-month shelf life
Sidel’s experts in liquid dairy and packaging performed a range of laboratory tests to determine the behaviour of different liquid dairy products (yoghurt, UHT white milk) in several PET barrier solutions (PET multi-layers and mono-layer with different rates of TiO2).
The scientists evaluated different caps’ opacity, to achieve the optimal light and oxygen barrier, and ensure the product’s stability without any alteration in terms of taste or colour. All these analyses confirmed that the combination of approved barrier PET and cap solutions with the Sidel aseptic filling packaging solution will allow reaching a five-months yoghurt shelf life, plus safety throughout the supply chain for distribution at room temperature.
Designed for future production demand
As part of the changes and plans to diversify their portfolio with more value-added products, the Chinese dairy is using PET packaging to help them advance as a business by offering new consumer experiences compared with the traditional carton format while allowing a more flexible production. The Sidel Aseptic Combi Predis are equipped with specific dosing valves with wider diameter and a low-high speed regulation to get prepared for the future market requirements.
