Fulfilling the potential of bottled water (continued)

The single-serve market today generally requires highly efficient output at maximum speed.  Here, speed typically is a key driver for the reduction of total cost of ownership, and production rates usually range between 40,000 to 80,000  bottles per hour (bph).  Conversely, there also is a strong demand for flexible lines capable of producing multiple formats at lower speeds, with production rates from 20,000 to 60,000 bph.

The drive for lightweighting has brought big reductions regarding a bottle's environmental impact and the cost of packaging.  Today's producers are striving for the lightest possible bottle with the best mechanical performance, with the limits of lightweighting yet to be reached.  During the next three years, the weight of a 1.5-liter PET bottle, for instance is expected to fall below 20 grams.

However the drive to take lightweighting even further must not compromise on performance, appearance or the feel of the finished bottle.  Of significant benefit in this respect are solutions providers who have a comprehensive overview of all industrial processes involved in PET liquid packaging.
