The sealing performance of a plastic bottle directly affects:
- How long can the contents of the bottle be preserved?
- Whether leakage will occur during transportation?
- The customer's impression of your brand.
Even a tiny gap can cause:
- Liquid leakage
- Loss of internal gases
- Entry of bacteria
Therefore, our sealing test:
✓ We use negative pressure 27kPa vacuum to simulate harsh environments.
✓ Only 2 minutes of testing can detect any problems.
✓ Ensure that each bottle is sealed firmly and reliably.
Test standards and processes
- Test conditions
Continuously pressurize for 2 minutes in a vacuum environment with a negative pressure of 27 kPa.
- Judgment criteria
Qualified: No deformation of the bottle, no bubble overflow, normal pressure fluctuation.
Unqualified: Leakage, bottle collapse, abnormal pressure (process defects require re-inspection).
Applicable scenarios
Health care product bottles, medicine bottles, cosmetic bottles, and other fields that have strict requirements on sealing.
