PFASs are polyfluoroalkyl chemicals commonly used in food packaging due to their resistance to oil, grease, moisture and stain resistance. They are applied to everything from fast food burger/sandwich wrappers to pizza boxes in food packaging. PFASs are also used on fabrics such as carpets, furniture and backpacks for stain resistance.
Essentially hydrogen atoms are replaced with fluorine atoms terminating with a Carbon chain. The PFASs are similar to Teflon (PTFE) used in non-stick frying pans. The danger with PFASs in food packaging is that if too much of this grease resistant coating is applied in food packaging, it can migrate into the food that we ingest and potentially increase cancer risks.
Therefore, it’s critical that food packaging suppliers measure and control the amount of PFASs applied to their paper and board lines. Near Infrared Cross Direction Profile Systems provide this measurement that can be sent to a Programmable Logic Controller (PLC) to precisely control the amount of PFAS being applied and they can also archive data.

Moisture barrier coatings are used to prevent moisture migration and preserve quality and shelf life of food products.
Many moisture barrier coatings are relatively thin in the order of 0.5 lbs/ream (per 3000 Ft²) or less. These coatings can easily be measured with Near Infrared Transmitters on printed substrates to optimize the coating thickness and insure a uniform Cross Direction Web Profile. Measurement data can be archived in roll reports that are time and date stamped for future reference in the event of customer complaints or other issues. These reports can also be used to compare the performance of different shifts on production runs.
Coatings and adhesive need to be applied in sufficient amount to meet specifications. Without a method to measure the deposition, many manufacturers apply more coating than needed resulting in a higher production cost. Too little applied coating will not provide the needed barrier to prevent the migration of moisture that can result in spoilage and an adverse impact on taste, texture and shelf life.
Stopping the line to collect lab samples slows production and does not supply archiving capabilities for roll or production runs. On-line continuous measurement of coating speeds start up, increases production and in-specification product.
The wet water based coated substrate typically passes through a dryer and then a re-moisturizer where a separate moisture measurement system supplies the output to control the moisture profile and minimize or eliminate lay flat and edge curl issues.
Plant managers are often concerned about coating consumption which impacts the profit margin on specific orders. Coating calculations determine the amount needed for a specific product run and the cost of coating associated with that product run. For instance, if a 40 inch wide web with a target of 1 wet lb per 1000 ft squared and an anilox volume of 14 BCM is being manufactured, both the weight in pounds and volume in gallons can be calculated. If the web width for another version of the same product is increased to 80 inches, the consumption significantly increases but it is not a simple doubling of necessary coating as that is a function of increased area not simply web width.
Near Infrared technology employed on-line can calculate the continuous consumption to aid in monitoring the production run or roll consumption when incorporating other parameters.

Tobacco moisture measurement with Near IR technology is long established throughout the world as accurate and reliable. Tobacco nicotine measurement on-line is of questionable value for a number of reasons.
GC, GC-MS, HPLC and HPLC-MS can all be used for tobacco nicotine determination in the laboratory. Near IR full spectrum analyzers utilizing PLS or other suitable chemometric treatments can also be employed in the laboratory on ground samples. The simplest and least expensive technique is GC. The levels of detection in a laboratory are in the ppm range rather than the % range that may be obtained using filter photometer NIR equipment on-line.
The difficulty with on-line nicotine measurement is that nicotine is not distributed evenly throughout the plant. The stem and the leaf and even within a single leaf contain significant variation in nicotine content. So, if you have more stem or less stem in the sample that alone shifts the nicotine measurement. Moisture equilibrates throughout the tobacco product, nicotine does not.
To indicate the accuracy of an on-line trend measurement of nicotine we need to determine the sample collection reproducibility and the sample analysis accuracy. The best way to do this is with 3 sets (or more) of double blind samples analyzed by a certified laboratory for nicotine content.
This means that two separate grab samples from the measurement point need to be collected at three different times. Hopefully the nicotine level is at a different level for each collection time. Otherwise it will be necessary to collect additional samples to create a range of nicotine levels.
When the samples are sent to the lab, the lab does not know which samples were collected at the same time, they are “blind” to this information to avoid bias in the analysis. The resulting data will determine how reliable the sample collection method is and the homogeneity of the samples collected.
Nicotine and related alkaloids/metabolites can be measured in the Near IR with chemometric treatments. The wavelength selection is the not the limiting factor in the measurement, it is the nicotine stratification throughout the plant. We believe that sample variation due to nicotine stratification makes a claim of absolute measurement on-line with photometers questionable at best.
Two papers of interest on nicotine variation within the tobacco plant can be viewed via hyperlinks below.
