Wisemini Aihua paper desiccant sachet/packet is a compact desiccant especially designed for small moisture-proof packaging applications. The sachets contain either white silica gel or orange indicating silica gel. Both have excellent absorption abilities, stable performance, are harmless to the touch and non-toxic. The indicating silica gel will change from an orange color to a light green after absorption capacity has been reached and signifies that the silica needs to be replaced. Aihua paper has good ventilation and is highly transparent so that the silica gel color change can clearly be seen. This type of paper is widely used for in vitro diagnostic reagents as well.

Diagnostic Reagent Desiccant-video Wisesorbent Technology

1. What is Aihua Paper?
Aihua paper is an inhouse developed non-woven and transparent material. This not only allows the desiccant material to be seen throughout the entire sachet, but also high breathability as well.

2. What type of ink do you use?
Our Wisemini Desiccant Sachets all utilize FDA approved water based ink and are non-toxic. Additionally, no ink is printed on the desiccant bag edges leading to higher strength edges.

3. How do you seal your desiccant sachets?
Each Wisemini Aihua Paper Desiccant utilizes an ultrasonic seal, this seal is unique as it only utilizes sound waves and does not use any sort of glue. The transparency in the middle allows cutting machines to scan and detect where to cut and then later dispense the desiccant properly.

4. How many sizes do you have in total?
There are 5 different standardized sizes of Wisemini Aihua Paper Desiccant ranging from 0.5-5g.

5. Why use white silica gel together with indicator gel?
White Silica Gel, when compared to other types of silica gel, has the highest overall adsorption rate while orange indicator gel allows you to see when the desiccant needs to be replaced or has absorbed all the humidity it can fully.

6. What type of products should use Wisemini Aihua Paper Desiccant?
Wisemini Aihua Paper Desiccant bags are great for small style packaging for medical products and diagnostic reagents. Anything that needs to be protected and be safe from humidity while also needing to test certain parameters needs to be accurate, and the transparency and indicator gel ensures the people who use them that the readings are correct.

Indicating Silica Gel is comprised of a naturally occurring mineral silicon dioxide that is purified and processed into a beaded form. When the beads are dry, they appear yellow/orange in color, and when they have become saturated with moisture to about 15% by weight, the beads will change to a green color. This type of indication enables users to visually confirm when the desiccant needs to be replaced or regenerated.

In this chart we can easily see that indicating silica gel has similar absorption ability with A type silica gel, at the same time it can change color when absorbing the humidity.
