C-Itech: Thin-Walled Glass Bottles
C-ITECH: a new technology for shaping drawn glass
C-itech is developing a technology that makes it possible to shape drawn glass into complex forms. The process enables the creation of thin-walled glass bottles with significantly less weight than conventional glass solutions.
Lightweight glass bottles
Using drawn glass reduces the amount of material required for the same capacity.
For a 30 ml bottle, C-itech reports that it can achieve a weight of just 12 g, compared with 69 g for a conventional glass solution.
This weight reduction also lowers the weight transported and, as a result, fuel consumption and the CO₂ emissions associated with transportation.
Complex shapes in drawn glass
Drawn glass is already widely used, particularly in the pharmaceutical industry, but until now its use has largely been limited to cylindrical shapes.
C-itech has added an additional step to the process, making it possible to create more complex forms. The technology therefore opens up new possibilities for bottles with a greater level of customisation.
An industrial process that differs from traditional methods
The technology developed by C-itech is based on an industrial process that differs from conventional glass bottle manufacturing methods.
Several prototypes have already been produced and tested in partnership with a major cosmetics group. According to C-itech, the validation process revealed no major technical issues and confirmed both the usability of the final product and its suitability for the identified application.
Production based in Chartres
C-itech’s production site is located in Chartres, at the heart of Cosmetic Valley and close to its customers.
Reducing bottle weight also provides an opportunity to lower the CO₂ emissions associated with transportation.
A technology currently under development
The technology is currently in the development phase.
Work carried out with a cosmetics group has already enabled the production and testing of several types of samples. C-itech sees particular potential for this technology in the luxury and premium sectors, where the ability to create complex shapes can meet growing demand for bottle customisation.
An end of life integrated into existing recycling streams
The bottles are made from soda-lime glass, a material that can be recycled indefinitely.
After use, they can be placed in existing glass collection systems and enter established glass recycling streams.
A technology combining bottle lightweighting, reduced glass consumption and new possibilities for complex shapes in drawn glass.
