Blue Indicating Silica Gel Packets
(Particle sizes: 1-3 mm, 2-4 mm, 3-5 mm) available
Blue indicating packets combine sealed breathable sachets with blue silica gel beads that turn pink after moisture uptake, giving users a clear replacement signal.
- Blue-to-pink color change for visible humidity status
- Sealed dust-control sachets for clean handling
- Typical moisture uptake reaches 30-40% of packet weight
- Breathable paper, non-woven, Tyvek-style or OPP material options
- Strong seal strength for storage and transport
- Carton and pallet export packing available
These packets are used when a buyer needs both moisture absorption and a simple visual inspection method. The indicator beads remain blue when dry and gradually change toward pink as the pack approaches saturation.
Common applications include instruments, electronics, sight windows, reusable kits, storage boxes and maintenance packaging where operators need to know when to replace or regenerate the desiccant.
