Leak Detection in Refillable PET Bottles

Leak Detection in Refillable PET Bottles [1] - Antares Vision Group

Do your returnable bottles have cracks, breaks, or hard-to-find leaks on the production line? The current inspection systems in use are ineffective because the bottles are not flexible? The PCS REF PET solution from Antares Vision Group uses innovative laser spectroscopy technology for inline leak detection in rigid refillable PET bottles, ensuring precise and reliable quality control.

PCS REF PET: The Innovative Solution for Leak Detection in Refillable PET Bottles

  • The repeated use of refillable PET bottles can cause wear over time, reducing their rigidity and strength, increasing the risk of leaks or breakage. This makes accurate quality control essential to detect micro-leaks of liquids which could compromise the product’s characteristics and safety.
  • Due to their rigidity, traditional methods based on compression are not applicable. However, the PCS REF PET solution, based on laser spectroscopy, allows inline measurement of the pressure in the bottle’s headspace, detecting any leaks or breakages in real time.
  • The laser beam is positioned at the level of the bottle’s headspace, allowing pressure measurement at production speed without direct contact with the container. This fast, reliable, and precise method ensures that refillable PET bottles are leak free or micro-leak free, providing manufacturers with: Product quality – Prevention of issues during transportation -Reduction of market complaints – Increased production line efficiency

Conclusions Ensuring the integrity of refillable PET bottles is essential to maintaining high quality and sustainability standards. PCS REF PET offers an innovative and reliable solution for inline leak detection, overcoming the limitations of traditional methods. Thanks to laser spectroscopy, manufacturers can ensure precise quality control, prevent defects that could affect production efficiency, and avoid problems during transportation and storage.

Investing in this technology means reducing waste, improving sustainability, and building consumer trust.
