Q8: What are Cosjar's testing standards for leakage and vacuum retention? | Innovative Skincare & Cosmetic Packaging - COSJAR

• Jars: Tested by filling with water and placing them sideways for 24 hours to ensure zero leakage (jars are not designed for vacuum extraction tests).• Bottles: Subjected to strict vacuum testing at -600mbar for 2 minutes.Tip: Leakage can be influenced by closure torque or uneven liners/bottle necks. We verify seal integrity based on standard industrial torque charts (e.g., Neck size:18mm = Min 80N.cm). Leveraging cutting-edge technology, COSJAR offers advanced solutions in beauty packaging.
