A revolutionary bottle line at our Varennes-sur-Fouzon site

17 February 2009

In 2009, LSDH decided to install the world’s first dry disinfection for blow-moulding and bottle filling line at its Varennes-sur-Fouzon site. The particularity of the process that LSDH has put in place lies not only in a dry disinfection of the packaging (H2O2 gas replacing a liquid solution of H2O2 and water) before conditioning, but also in the disinfection of packaging prior to preform blow-moulding. This way the surface of material to be disinfected is 10 times smaller than when the packaging is ready to be filled.

The particularity of this conditioning machine also lies in its compactness; it incorporates three functions in a single machine: blow-moulding, filling and bottle capping, all of which make it possible to guarantee maximum hygiene levels in an industrial environment.

This revolutionary line packages milk as well as fruit juice with a provisional available capacity of around 120 million packaging containers a year.

Many advantages:

  • Reduced natural resources abstraction
  • Four times less water used compared with a standard solution
  • Four times less energy used for disinfecting packaging (since the liquid disinfection system required a large quantity of water to be heated in order to obtain effective disinfection)
  • A bottle weight 10% lower than with standard disinfection. In fact, the heat required to disinfect packaging risks distorting it if the packaging has a very thin barrier and this necessitates a high bottle weight. Since the preform has a far greater thickness before blow-moulding than the end bottle, the total weight can be reduced while at the same time keeping a bottle that conforms to requirements. The saving on packaging is currently estimated at 10% although this technology makes it possible to envisage greater savings eventually by strengthening the container with a stronger label (yoghurt pot type)
  • Eco-friendly packaging: the recycling sector for PET bottles is in full expansion. This packaging is totally recyclable. The use of this packaging for milk removes the need for an aluminium seal and so considerably reduces the weight of the packaging compared with a standard milk bottle made from HDPE
  • Carbonated form disinfection means a lower use of chemical products (three times less). Discharges from the treatment plant are also contain less disinfectant products
  • Lower unit cost for the bottle; the reduction of environmental abstractions has an effect on the unit cost of the packaging: lower consumption of water, of chemicals, of energy and of plastic
  • Quality and yield: less initial contamination of the bottle before filling, better line yield as less equipment is involved and also few interfaces between items of equipment, better line driving as the blow-moulding part is very close to the filling part, less downstream regulation of filling, continuous positive transfer of the preform to the filled bottle
