    The Key Textile Testing Machines of TESTEX - Testex
    A PE (Polyethylene) Water Vapour Permeability Tester, or WVTR (Water Vapor Transmission Rate) Analyzer, measures the rate at which water vapor passes through plastic films, sheets, and packaging materials. Using infrared sensors, electrolytic sensors, or gravimetric (cup) methods, these instruments are crucial for ensuring the moisture barrier quality of PE packaging in food, pharmaceutical, and electronics industries. 
    Key Features and Capabilities: 
    • Measurement Standards: Complies with industry standards such as ASTM E96 (gravimetric), ISO 15106, GB/T, and JIS L1099.
    • High Sensitivity: Detects moisture permeability for various barrier materials, with sensors offering high resolution, such as

      )
      .
    • Simultaneous Testing: Advanced models offer multiple independent chambers (often 3 or more) to test samples at varying temperature and humidity levels, improving testing efficiency.
    • Applications: Ideal for evaluating PE films, pouches, pharmaceutical packaging, and other high-barrier materials. 
    Popular Models and Manufacturers: 
    • Labthink: Offers the C390M (infrared) and other instruments specialized for packaging material testing.
    • GBPI: Produces the W405L and high-precision testers for films and containers.
    • Labtron: Provides the LWPT-B12 and LWPT-C10, which utilize cup methods to measure water vapor transmission.
    • Testex: Manufactures automated testers like the TF165B, suitable for textiles and film. 
    These testers ensure that PE materials meet required, low-moisture barrier standards necessary for product integrity.

    ASTM E96 Water Vapor Transmission Rate Test Methods

    In the Desiccant Method, the test specimen is sealed to a test dish containing a desiccant, and the assembly is placed in a controlled atmosphere. Periodic weighings are used to assess rate of water vapor movement through the specimen into the desiccant.

    What is the permeability of polyethylene water vapor?
    Low-density polyethylene sheathing materials have water vapor permeabilities on the order of 10−8 at 22°C. High-density polyethylenes have permeabilities about one-third to one-sixth that of the low-density polyethylene. Copolymers of polyethylene have higher permeabilities than the homopolymer.

    What is the difference between ASTM F 1249 and ASTM E96?
    ASTM F1249 is typically used for plastic films and sheeting, while ASTM E96 is used for a wider range of materials, including textiles and paper. Additionally, ASTM F1249 is performed at a constant temperature and humidity, while ASTM E96 can be performed at different temperatures and humidity levels.May 29, 2024

    What is the WVP test for containers?
    Water Vapor Permeability (WVP) refers to the ability of a material to allow water vapor to pass through it via diffusion, driven by a vapor pressure gradient. It is the rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.
