The Ghostly NoBottle

Typically, when bottle weight is reduced, ribs are added to brace bottle walls. These bottles are brittle and noisy when compressed, which reduces shelf appeal and premium image.

17/08/07 Sidel has developed an elegant, high-performance package which it says is also the lightest PET bottle yet for water (9.9g per 500ml bottle).  The concept, dubbed NoBottle, is possible due to another Sidel innovation known as Flex, it says. Flex technology is based on flexibility and shape memory that allows packages to spring back to their original shape.

Typically, when bottle weight is reduced, ribs are added to brace bottle walls.  These bottles are brittle and noisy when compressed, which reduces shelf appeal and premium image.  The ribs also limit the possibilities for lightweighting.
 
NoBottle weighs 25-40% less than the average-weight water bottle of the same capacity (13g to 16g), resulting in less PET raw material required and less waste after consumption. 

Producing a 500 ml bottle weighing less than 10 g is an impressive technical achievement. Sidel looked at the entire manufacturing process, from blow molding to palletizing, to propose a simple solution to customers that could be tailored to their needs.
