Reversible Indicator Cards

Visual Moisture Monitoring for Dry Pack Applications

CCD Enterprise’s Reversible Humidity Indicator Cards (HICs) provide a simple, accurate, and cost-effective way to monitor humidity levels inside sealed packaging. These cards feature color-changing spots that reversibly shift between blue and pink (or brown to green, depending on type), allowing users to instantly assess relative humidity (RH) conditions during storage or transport.

Ideal for use with moisture barrier bags (MBBs), vacuum-sealed packaging, and semiconductor dry packing, our cards comply with JEDEC J-STD-033 and help protect moisture-sensitive devices (MSDs) from degradation and failure.
