What desiccant is used for moisture-proof aluminum foil
Source:
It is a packaging product that has not been replaced so far. Have, heat transfer, light, moisture and other potential, so its use is very common.
Aluminum foil is cost-effective, durable, lightweight and oil resistant. In addition, aluminum foil can block many chemicals, germs, water vapor and vapor, and has the characteristics of electromagnetic induction and non-magnetic barrier effect, so the following 7μm thin specifications of aluminum foil in the soft bag industry more and more popular, especially in the food packaging materials industry.
However, aluminum foil waterproofing membrane, with its too book, in the storage and transportation of the whole process if the tide, easy to air oxidation (white spot disease), and thus the aluminum waterproofing membrane waterproof countermeasures important. So how to avoid aluminum foil in the middle of the delivery of mold? What kind of desiccant to use better.
Aluminum foil manufacturers propose to use silica gel desiccant or mineral desiccant, not calcium isopropyl titanate desiccant or calcium-added live mineral desiccant. Strongly use silica gel desiccant or mineral desiccant, no-proof cloth has good air permeability, and good leakage characteristics (desiccant flash will lead to imprinting of aluminum foil, the whole bundle of aluminum foil will become waste).
