Product catalog summary

Cigarette Packaging Aluminum Paper Liner Moisture Barrier Testing

The aluminum paper liner in cigarette packaging serves as a vital barrier against moisture and odors, protecting the tobacco inside. Testing its moisture barrier properties is crucial, with the Water Vapor Transmission Rate (WVTR) being the most common measurement. This rate indicates how much moisture can pass through the foil over time.

Traditional Testing Method

The traditional "cup method" involves sealing the foil over a container with desiccant and measuring the weight gain of the desiccant as it absorbs moisture. Although simple and cost-effective, this method is time-consuming, often requiring days or weeks for results.

Advanced Testing Techniques

More advanced methods include the use of electrolytic detection sensors and infrared sensors. Electrolytic sensors use a dry carrier gas to transport moisture to a sensor, generating an electrical current proportional to the moisture content. Infrared sensors measure the absorption of infrared light by water molecules, providing fast and accurate results within minutes to hours. These methods are non-destructive, allowing further testing on the same sample.

Labthink Testing Systems

Labthink offers the C360H Water Vapor Transmission Rate Test System, based on the gravimetric method, conforming to ASTM E96 standards. The C306H system uses infrared sensors, conforming to ASTM F1249 and ISO 15106-2 standards, suitable for high and medium moisture barrier materials.

Standardized Procedures

International standards such as ASTM E96/E96M, ASTM F1249, ISO 2528, and ISO 15106-1 provide guidelines for sample preparation, environmental conditions, and result interpretation. These standards ensure consistency and comparability across testing facilities. The choice of testing method depends on accuracy, speed, and budget, with sensor-based methods preferred for demanding applications like cigarette packaging.

Conclusion

As the demand for functional packaging increases, testing methods continue to evolve for comprehensive evaluation. Labthink encourages collaboration for quality control and offers more information on their website.

Cigarette Packaging Aluminum Paper Liner Moisture Barrier Testing-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Cigarette Packaging Aluminum Paper Liner Moisture Barrier Testing The aluminum paper liner within the cigarette box acts as a crucial water vapor barrier, preventing the tobacco from absorbing unwanted moisture or odors. Testing the moisture barrier property of this foil is therefore essential, and various standardized methods exist to guarantee its effectiveness. The most common measurement is the Water Vapor Transmission Rate (WVTR), which quantifies how much moisture can pass through the foil over time. The traditional “cup method” involves sealing the foil over a container of desiccant and measuring the weight gained by the desiccant as it absorbs moisture that permeates the foil. While simple and inexpensive, this method is time-consuming, often taking days or even weeks to yield results. Labthink C360H Water Vapor Transmission Rate Test System is designed and manufactured based on the gravimetric determination method and conforms to the requirements of ASTM E96. It is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other packaging materials in food, pharmaceutical, medical apparatus, building materials and consumer goods, etc.

Cigarette Packaging Aluminum Paper Liner Moisture Barrier Testing-2

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 More advanced techniques offer faster and more precise measurements. Methods utilizing electrolytic detection sensors employ a dry carrier gas to transport any permeated moisture to a sensor that generates an electrical current proportional to the moisture content. This allows for rapid and highly sensitive measurements, ideal for high-barrier materials. Another efficient method uses infrared sensors. Here, infrared light is passed through the permeated moisture, and the amount of light absorbed by water molecules is measured....
