Product Principle and Function

Shock labels, also known as shock indicators, are octagonal self-adhesive labels mainly affixed to the outer packaging of goods. They feature a specific impact design with an internal crystal tube sensitive to impact force.

When the indicator is subjected to external force exceeding its set range, the middle crystal tube turns from white to red, and this color change is irreversible.

This means that when your precision or fragile goods experience rough handling or strong vibration due to improper operation during transportation, the label on the outer packaging will accurately record this situation, reminding the recipient that the goods may be damaged. This facilitates on-site unpacking inspection and helps hold the carrier accountable.
