Test the Barrier Properties of Coated Paper as Plastics packaging’s Sustainable Alternatives

Keywords: Coated Paperboard, Permeability Testing, Oxygen Permeability, Water Vapor Permeability, Sustainable Packaging, Differential Pressure Method, ASTM D1434, Cup Method, ASTM E96, Single-Use Plastics Replacement, environmentally friendly materials

The global shift away from single-use plastics has driven increased demand for paper and paperboard packaging. However, traditional polyethylene (PE) coated options often pose environmental concerns due to slow degradation in landfills. This report explores the growing need for measuring the permeability properties of coated paper and paperboard alternatives.



The current focus is on coated paper and paperboard designed as replacements for single-use plastics. Differential pressure based on ASTM D1434 standard is applied for materials Oxygen and Gas Permeability Testing. Labthink C101B, C106H, C130H and VAC-V2 are Gas Permeability Test Systems adopting Differential pressure method providing a wide range of test specifications and abilities.
 



C106H Gas Permeability Test System is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at different temperatures.

For Water Vapor Permeability Testing ASTM E96 compliance cup method is adopted. Labthink C360H and C360M Water Vapor Transmission Rate Testers designed and manufactured conforming ASTM E96.
 



C360H Water Vapor Transmission Rate Test System can be used to measure the water vapor transmission rate of barrier materials. C360H is equipped with precision made test dishes, highly accurate balance, embedded professional software which supports automatic controlling of temperature, humidity and flow rate precisely and guarantees the testing sensitivity and repeatability of the test results. C360H 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.

This test results highlight the importance of testing the permeability of coated paper and paperboard packaging. The methods described (differential pressure for gas and cup method for water vapor) enable manufacturers to ensure their products meet required barrier properties. This is crucial for maintaining product quality and shelf life while minimizing environmental impact.

As the use of coated paper and paperboard packaging grows, reliable testing methods are essential for developing sustainable solutions. The Labthink instruments and methods discussed in this report offer efficient and accurate ways to measure gas and water vapor permeability, allowing manufacturers to optimize packaging performance and contribute to a more sustainable future.



As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films.

Moisture Resistance Testing of Thermal Conductive Silica Gel Pads

Thermal conductive silica gel pads, crucial components in electronic devices, require effective moisture resistance to ensure optimal performance and longevity. This article delves into a comprehensive testing method for evaluating the water vapor transmission rate (WVTR) of these pads. Electronic components are sensitive to moisture, which can lead to corrosion, short circuits, and reduced reliability. Thermal conductive silica gel pads, often used to facilitate heat dissipation between electronic chips and radiators, play a vital role in preventing moisture ingress. Their moisture resistance properties directly impact the protection of sensitive internal components. The electrolytic sensor method, a widely recognized standard, is employed to measure the WVTR of thermal conductive silica gel pads. This technique involves creating a controlled environment with a high humidity chamber on one side and a low humidity chamber on the other. A sample of the thermal conductive silica gel pad ...

Quality Requirements of Lithium Ion Battery Separators

Business Challenge Lithium-ion batteries have one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them one of the most popular types of batteries for portable consumer electronics in today’s marketplace. Lithium-ion batteries can be found in cameras, laptops, power tools, toys and more. However, as recent well-publicized recalls demonstrate, they can pose a risk of fire and overheating. In addition, they can suffer from a reduced lifespan if not properly treated. As a result, new and stricter requirements are being implemented globally to address potential hazards, leaving manufacturers and purchasers of products containing lithium-ion batteries to meet increasing requirements and overcome safety concerns. Lithium Ion Battery Separators A Lithium Ion battery Separator is a permeable membrane placed between the anode and cathode of a battery. The main function of a separator is to keep the positive and negative electr...

Introducing Vacuum Decay Testing Method for Pharmaceutical Packaging Integrity

Maintaining the integrity of pharmaceutical packaging is fundamentally essential for safeguarding product efficacy and patient safety, and vacuum decay testing stands as a highly reliable non-destructive method for verifying this integrity. This technique, particularly effective for blister packs, vials, and pre-filled syringes, identifies leaks without compromising product sterility or efficacy. Vacuum decay testing leverages the principle that a sealed package, when subjected to a vacuum, will exhibit predictable pressure changes if it's leak-free. Conversely, a leaking package will show a different pressure profile. Specific Vacuum Decay Techniques:   Differential Pressure Transducers: These precise sensors measure the difference in pressure between the vacuum chamber and a reference chamber. This allows for detection of very small leaks. Absolute Pressure Sensors: These sensors measure the absolute pressure within the vacuum chamber, providing data to determine the rate of pres...
