Impact Label | Wan-Yo | Shock Indicator for Shipping


Impact Label shock indicator for shipping, a.k.a. impact indicator, is a single-use impact detection device that activates (turns red) when an impact level exceeds the unit’s g force threshold. For various industries, transport shock indicators can be attached to your package or directly to a product inside.

When dropped, the color changes from white to red to indicate the impact. The red cannot be reset, allowing shippers to identify irresponsible handling in their supply chain. Furthermore, g force impact monitoring can detect potentially concealed damage products, reducing claims and alerting recipients to inspect items. According to one study, using a monitor reduces damage by 50% or more. We supply a variety of types and sizes. Stop your damaged deliveries with Impact Label, Clip Label, and Impact Tube today!

This product is a sister product to Leaning Label tilt indicator, and it is highly recommended to use them together.
