Stacking/Compression Test
This test is used to verify the packaging state, to check the compressive strength of the packaged-product through simulating the storage in storehouse or transportation, inspect the protection function during bearing a vertical pressure for a certain period. The test level depends on the pressure value, the loading speed and stacking time.
Two types of compression test:
a. Static compression: Simulate when the packaged-product stacked in the pallet, with a certain load for a certain period, check the deformation of carton, whether will affect the appearance and function of inner products.
b. Dynamic compression: Increase the force gradually, check the deformation whether beyond the restriction, in order to know the max compressive strength the packaged-product can withstand.
