The novel package, part of Tetra Pak’s Tetra Top packaging system, will initially be available in volumes between 500ml and 1000ml, for milk and juice-based products.

Each Carton Bottle package is made from a sleeve of carton material and an injection moulded plastic top. On Tetra Top’s Carton Bottles, this top is significantly elevated, and a screw cap fitted, to complete the bottle-like functionality.

The full name for this novel pack is Tetra Top Base Pacaya S38 Carton Bottle.

The Carton Bottle package is primarily positioned to compete with plastic bottles labeled using full-body shrink film.
The company claims Carton Bottle offers a better platform for communicating a ‘freshness’ image, thanks to its use of carton material together with a plastic bottle top that offers both a wide pouring hole and screw cap. It says other qualities that distance the Carton Bottle from its competitors are:

• Photographic quality flexo-process printing, directly onto all visible carton surfaces
• A safety membrane beneath the screw cap
• The fact that more than 50 percent of the material used to make each Carton Bottle is paper – a renewable resource.

To produce the new Carton Bottle, Tetra Top has further developed its plastic injection moulding technique.

A key component in any Tetra Top filling machine is the lid-forming unit (LFU) which injection moulds the polyethylene lids directly onto carton sleeves. This component has now been upgraded to ‘LFU G2’, a new generation lid-forming unit that opens up the potential for a full line of new Tetra Top openings.

Katrin Högbom, LFU G2 project leader, says, “Our previous LFU performed the world’s fastest plastic injection moulding procedure, but I’m proud to say our new LFU G2 spices up this record with even greater stability, lower maintenance and more consistent lid quality.”
