Tests for Laminated Pharmaceutical Packaging

To ensure the integrity and safety of pharmaceutical products, laminated films and pouches undergo rigorous testing.



Here are some critical test items, along with relevant standards, test methods, and instruments:

Barrier Properties:
  • Water Vapor Transmission Rate (WVTR): Measures the rate at which water vapor passes through the material.
    • Standards: ASTM E96, ISO 2528
    • Test Instruments: Gravimetric and Coulometric methods
  • Oxygen Transmission Rate (OTR): Measures the rate at which oxygen permeates the material.
    • Standards: ASTM D3985, ISO 15105-2
    • Test Instruments: Oxygen transmission rate analyzers
  • Carbon Dioxide Transmission Rate (CO2TR): Measures the rate at which carbon dioxide permeates the material.
    • Standards: ASTM D1434, ISO 15105-1
    • Test Instruments: Gas transmission rate analyzers

Labthink C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.



Mechanical Properties:
  • Tensile Strength and Elongation: Measures the material's resistance to breaking under stress.
    • Standards: ASTM D882, ISO 527
    • Test Instruments: Tensile testing machines
  • Tear Resistance: Measures the force required to initiate and propagate a tear in the material.
    • Standards: ASTM D1922, ISO 6383
    • Test Instruments: Tear testers
  • Seal Strength: Measures the bond strength between layers of the laminate.
    • Standards: ASTM F88
    • Test Instruments: Seal strength testers
  • Impact Resistance: Evaluates the material's ability to withstand impact forces.
By conducting these tests, manufacturers can ensure that laminated films and pouches provide adequate protection for pharmaceutical products, maintaining their quality and efficacy throughout their shelf life.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!

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...
