The shockwatch impact indicator is mainly used to apply on the shipment, but there are multiple packaging types of goods. It is mainly divided into “cartons” and “plywood crates.”
From the previous articles “What Is『G』 Of Shock Watch Indicator?” and “LATEST 3 Major Shock Indicator 『Price, Principle, Function』( Easy Grasp & Details )“, you have understood that the shockwatch impact indicator is received and activated under “exceeding the set impact force“.
The material and weight are so different between carton and plywood crate. Does the shockwatch impact indicator have a difference in activation heights on carton and plywood crate? Does the shockwatch impact indicator receive a different “G” number in the same impact force due to materials of packaging?
The answer is definitely YES!
Let’s see what the difference is when we do a drop test for carton and plywood crate under the same height and weight.
I. Actual Test
From the following two videos, the activation height of the shockwatch impact indicator is greatly different for cartons and plywood case. The reason is that the impact force is attenuated to different degrees due to the material. The harder the material is, the more direct and accurate the effect of impact force transmission is.

II. Activation Height
The following table shows the activation height meter after we did multiple tests for shockwatch impact indicators on the carton. Every model of shockwatch impact indicators has its activation height.
Impact Label Test
From the previous article “『Correct Apply Position』Shock Indicator Labels“, you know that the shockwatch impact indicator is to be applied on the corner to the package. The reason is that the attenuation of the impact force transmitted to the shockwatch impact indicator is minimal after being affected by the material of the package.
On the other hand, if the shockwatch impact indicator is on the wrong placement, it also affects the activation height of the shockwatch impact indicator.
In order to avoid this mistake, we also wrote “『4 Ways』 To Choose Shock Indicator Models“, so that you can select the most suitable model for your packaging.
