Flexibile Packaging Moisture

Flexible packaging acts as a tough protective barrier to prevent the entry of contaminants, tampering and sanitation issues. Flexible packaging also protects the food products’ freshness, nutrition and shelf life. Other packaging may be for communicating information about product use, convenience, unit size, or dispensing information. Still others are to avoid pilfering and shoplifting. Regardless of the use of the packaging, the manufacturing process involves coating a paper product in a timely, cost-effective way. Moisture must be controlled, and coating thickness needs to be measured.


With the help of industry partners and 40 years of knowledge, MoistTech has developed the IR 3000 flexible packaging moisture sensor. measure the moisture levels as well as water and solvent based coatings and coat weight thicknesses during the paper/converting process.


In the paper/converting process there are many locations throughout manufacturing that the flexible paper moisture sensor can be used. The location is often determined by the space availability and accessibility on the machinery as well as manufacturer’s moisture control plan. Once installed, a manufacturer can continuously monitor the process and can control the moisture content or package coating, either manually or automatically.

Benefits of Flexible Packaging Moisture Control

MoistTech is very experienced with the requirements in the paper/converting process. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical moisture accuracy is about ±0.05%, coating accuracy varies from 0.1 to 0.01 micron depending on coating type. Typical analog range is 0-10% moisture and up to as much as 40%, subject to application. The outputs can be adjusted to optimize PLC or recording requirements.
