4 x 4" - "Caution Moisture Sensitive Devices" Labels

These 4x4" pressure-sensitive labels carry a "Caution Moisture Sensitive Devices" warning, providing a clear visual alert on outbound shipments containing electronics, sensors, PCBs, or other components susceptible to moisture damage. The large label face ensures the warning is readable at a glance on standard shipping cartons and outer packaging.

Applied directly to corrugated boxes, poly mailers, and poly bags, these labels communicate handling requirements to carriers, warehouse personnel, and receiving teams at every point in the supply chain. They are especially well-suited to electronics manufacturing, PCB assembly, semiconductor distribution, and medical device fulfillment operations where moisture-sensitive component protection is a compliance requirement.

Each roll contains 500 labels wound on a 3" diameter core, compatible with standard tabletop and wall-mount label dispensers. The pressure-sensitive adhesive bonds quickly to corrugated, poly, and similar packaging surfaces without tools or heat. Compatible dispenser options are available separately.
