SMI: From the source to the table quality in a rPET bottle

Designed to ensure respect for the environment, the new eco-friendly bottle is the result of joint work between the specialists at Danone and at SMI, which has allowed to develop a preform able to guarantee the constant resistance of the container during the stretch-blow moulding process.

Packaging, indeed, plays a key role in the maintenance of water purity and the high regard of environmental issues has led Volvic to develop innovative solutions for the recycling of PET, so that a new bottle can be produced from an old one.

The complete production process has been designed so that every step of the bottling process is kept under constant control; for this reason, the machine supplied by SMI has been integrated with sophisticated inspection systems, that, starting with the preforms, carry out a long series of checks to maintain the quality and the purity of the spring water.

Main advantages:

• compact and flexible solution with low operating and maintenance costs;
• isolating system between the dry area of the stretch-blow moulder and the wet one of the filler through a jet of sterile air in excess of 5PA, that acts as a clean room and guarantees a clean, hygienic filling system;
• innovative preform suction system, situated on the heating tunnel infeed star to remove any tiny impurities;
• machine equipped with sophisticated inspection systems with cameras, in order to guarantee the quality of the bottled water and monitor the production process;
• preforms are blown with sterile air in a sterile environment; this sterility is maintained for all the process of filling and capping;
