In small to medium sizes as well as in packs of six, Stack & Pack bottles benefit all key players in the value chain

With its new stackable bottle concept, Stack & Pack, Sidel is providing the first stacking solution of its kind for mid-size bottle capacities from 250 ml up to 1 L. A deeper than usual concave indentation at the base of each bottle (Sidel's patented "stroke base" technology) enables highly efficient stacking. The neck of the bottle below fits into the base of the bottle above, significantly reducing the required amount of stacking space and eliminating any need for interlayers.


Once the bottle is filled and capped, a stretch sleeve is wrapped around to form a pack of six bottles, just like an elastic band. The compact stack enables 10 layers instead of six to fit on a standard European pallet, increasing the number of bottles on a pallet by 40 per cent. Stack & Pack is suitable for sensitive products such as juices, liquid dairy products and milk, and addresses the needs of all supply chain players, from the producer to the end-user.


Economical advantages


Brands, private labels and co-packers benefit from many economical advantages: expenditure for carton interlayers can be deleted from the account books, storage space is optimised and fewer pallets in trucks are required to transport the same volumes of full pallets. The reduction of blowing pressure by up to 10 bars using the stroke base solution during production generates further energy savings. The stackable bottles can be produced in various shapes and sizes; their broad surface area offers great branding flexibility. And the stack-ability of the bottles puts an end to crushed bottle necks. Stack & Pack also offers retailers multiple advantages. Because the pallets are delivered without interlayers, no waste needs to be removed before displaying the bottles. The increased number of bottles stacked on each pallet results in less restocking of shelves. Additionally, the look and feel on the shop floor is a lot more attractive, offering additional new shelf-end promotional opportunities and generating more purchasing incentives. High product availability and rotational product presentation result in higher visibility and, in the end, higher sales volumes.


Easy handling at all levels


Last but not least, consumers also benefit from the Stack & Pack concept. For eco-conscious customers, the use of 100 per cent recyclable PET is a buying argument, while the use of a safe cap reduces waste. Compared with classic milk bottles, for example, no foil is needed to secure the cap. The bottle opens conveniently right from the start. The bottles are also very easy to grab and pour. And minimum space is required for storage in cupboards, fridges or car boots. With this holistic packaging concept, Sidel is strengthening its position as a global solution provider for the beverage industry. The technology is up and running at Sidel's production facility and is ready for field tests at customers' plants. Sidel's pioneering Stack & Pack solution will be displayed for the first time at Anuga FoodTech, 27-30 March 2012, hall 7, stand A11-B24.


Product Package Interaction (PPI)
The release of new beverages, recipes or bottles is a complex business, especially with sensitive drinks. Sidel has invested one million euros in R&D in order to integrate
all required development steps into a comprehensive offering. With its long-standing expertise,
the Sidel Group is able to evaluate and identify the most suitable materials, bottle shapes and caps for each drink, taking into account the specific characteristics and issues of each drink and each producer.

At the pilot plant for aseptic production, Sidel's experts reproduce all industrial packaging steps on a reduced scale. Different PET packages are tested under simulated real-life conditions. This includes physical, chemical and sensory analyses, as well as studying
different indicators and beverage sterility validation.
