Implementation of CTE-I<\/strong><\/span><\/h2>\n

The CTE-I box is used in all industrial sectors where the integrity of packaging is a quality or safety requirement:<\/p>\n

Agri-food<\/span><\/strong>
\nLeak detection on pouches, doypacks, trays, yogurt cups, and modified-atmosphere packaging. An undetected leak can lead to product contamination, a shorter shelf life, and costly product recalls.<\/p>\n

Cosmetics and Fragrances<\/span><\/strong>
\nLeak testing of skincare product pouches, cosmetic blister packs, and wipe pouches. Immersion testing allows for the precise identification of the source of a leak before the product is released to the market.<\/p>\n

Pharmaceutical<\/span><\/strong>
\nVerification of the integrity of heat-sealed primary packaging (blister packs, tablet pouches, sterile pouches). The traceability of the test is ensured by the LNE\/COFRAC calibration certificate provided with the CTE-I<\/p>\n

Aeronautics and Industry<\/span><\/strong>
\nLeak testing of mechanical assemblies, seals, connectors, and enclosures. The flexibility of the vacuum settings (0 to -0.85 bar) and delay settings (0 to 999 seconds as standard) allows the test protocol to be tailored to the specific requirements of each application.<\/p>\n

How does the ASTM D3078 immersion test work?<\/strong><\/span><\/h2>\n

The immersion leak test according to ASTM D3078 is one of the simplest, fastest, and most cost-effective methods for detecting leaks in flexible packaging. The 4-step process:<\/p>\n

    \n
  1. Immersion: The package is placed in the tank filled with water and held submerged by the perforated Plexiglas presser.<\/li>\n
  2. Vacuum application: The chamber is closed, and a vacuum is gradually applied via the compressed air supply. The vacuum expands the air inside the package.<\/li>\n
  3. Observation: The operator observes the surface of the package through the transparent box. Any leak is indicated by a continuous or intermittent stream of bubbles at the location of the defect.<\/li>\n
  4. Reading and result: The vacuum level reached and the duration of the test are read on the vacuum gauge. The result is either compliant or non-compliant, depending on the protocol defined by the user.
    \nThis test is non-destructive for compliant packaging (samples that do not leak may be returned to the production batch).<\/li>\n<\/ol>\n
