In plastic packaging, air tightness is a critical quality standard, especially for pharmaceutical, supplement, and food applications.
🏭 How the Air Tightness Test Works
During production, each bottle undergoes this test using an automated robotic system:
- Mechanical Arm Grip
A robotic arm securely grips and seals the bottle neck to simulate the final capping condition.
- Air Injection
Compressed air is injected into the bottle at a controlled pressure level.
- Leak Detection
Sensors monitor any pressure drop or air escape. If pressure remains stable, the bottle passes; if not, it is automatically rejected.
This test ensures each bottle meets required sealing standards before it leaves the production line.
🏆 What Sets Mingda Apart
Not all factories perform airtight testing for every bottle. At Mingda, we include it in our standard quality control workflow, especially for critical-use packaging like small travel pill containers, Protein powder jars, and pharmaceutical packaging.
