(1) Environmental testing
The transportation test for packaging experiences different ambient temperature and humidity changes during transportation and storage, and transit test packaging measures the resistance of the package to temperature and humidity. Changes in temperature and humidity will reduce the mechanical properties of packaging and reduce the protection of the items in the packaging. For example, in high humidity environment, the carton will soften, the strength of the box will decrease, and the tape will fall off; in low temperature environment, the plastic packaging will become brittle, and the impact resistance will be reduced.
(2) Drop test
Simulate the vertical impact of the transport unit during transportation and storage, and test the impact strength of the package. For example, forklift misoperation, manual handling errors, etc., often cause the outer packaging to burst, the paint film to be damaged, the metal deformation, the plastic rupture, and the desoldering of the components. For carton drop test.
(3) Compression (stacking) test
ORT testing simulate the vertical pressure of the transport unit during transportation and storage, and test the pressure resistance of the package. For example, in the long-term stacking of warehouses, the strength of the package will be attenuated; in the vehicle-mounted stacking, the road conditions, the new and old vehicles, the speed of the vehicles, and the placement of the transport units will produce different pressures.
(4) Vibration test
Random vibration test simulate the dynamic impact of the transport unit during transportation, test the strength of the transport unit and find the resonance point. The vibration test can optimize the packaging and avoid the resonance point. For example, vibrations such as road bumps and aircraft encountering turbulence often cause precision instrument parts to fall off and shift.
(5) Incline impact test
Simulate the impact of the transport unit during transportation and storage, and test the strength of the outer packaging and the cushioning performance of the inner packaging. For example, during the hump of train marshalling and vehicle braking, the rigidity of the packaging is too large and it is easy to crack. When the impact energy absorbs less, it may even be transmitted to the product inside the packaging, causing damage to the product.
(6) Clamping test
Simulate the horizontal pressure of the transport unit during transportation and storage, and test the clamping strength of the package. For example, unloading with clamping trucks, manual handling of small packages, etc.
(7) Low pressure test
Low pressure air test: The air pressure change experienced during transportation and storage can test the sealing effect of the package. For example, during high-altitude transportation and air transportation, low air pressure often causes the sealed bag to burst and electronic components to fail.
