    MOCON, Inc., the world’s leading manufacturer of permeation instrumentation, has developed a new oxygen transmission rate test instrument which accurately and repeatably measures barriers to 5x10-4cc/(m2 x day), ten times lower than previous levels. The OX-TRAN® Model 2/21 10x system measures films or packages at precise temperature and relative humidity conditions. Learn More...

  • Important Factors in Permeation Testing

    WHAT IS PERMEATION?
    Graham’s Colloidal Diffusion illustrates the three-step process of permeation through a material. The first step is the sorption of the permeant into the material. Next, the permeant diffuses through the material followed by the final step where it is desorbed from the other side. This entire process is driven by a concentration difference or gradient. Molecules will permeate from the high concentration side of the material to the low concentration side. This will continue until both sides are at equal concentration levels. Learn More...

  • New Portable Carton Tester launched at PackTech Feb 2014

    The new Newton Portable Carton Tester is being launched at this year’s Packtech exhibition, NEC 26-27 Feb 2014.

    The Newton PCT (portable carton tester) is easily calibrated and fully transportable for rapid quality testing in situ.  It is suitable for testing whole cartons made from corrugated, paper board and waxed carton board up to 230mm wide and 8mm thick.

    Housed in a rugged Storm case with pre-programmed integral lap top, the PCT combines three essential quality control tests.  It measures crease strength, spring back and box-forming force. It also evaluates friction properties to identify potential carton sticking and feeding problems. Data analysis and reporting is provided through the unit’s integral graphic user interface.

    The PCT measures the torque required to form a crease and produces an instantaneous curve that shows the torque for every degree of deflection.   The results facilitate easy comparison between batches and carton types to help achieve performance consistency over time and for multiple sites.

  • A new standard in Oxygen Analysis

    by Phil Neal

    The OpTech-O²-Platinum is a non-destructive Oxygen analysis device with 3 test modes for measuring headspace O², dissolved O² in a liquid and barrier film O² permeation properties.

    Because the sensor does not consume any gas, measurements can be repeated on the same pack to create an O² v Time profile over the product shelf life. Applications include modified atmosphere food packaging, beverage containers, and pharma/medical packs, in both R&D and QC environments.

     

    • Quality Control checks of MAP packs, single value or time profile
    • For liquid contents, measure headspace O² and dissolved O²
    • O² permeation rate of packages & films, including porous & perforated films
    • Very small headspace volume packs, and vacuum packs
    • Determine shelf life for an Oxygen sensitive product
  • Heat Seal Parameters of Flexible Polymer Film and Finished Package Seal Integrity - Quality Control inspection issues

    For many products, the impact of packaging on shelf life and product safety is critical to success. Packaging technical teams will carefully specify packaging material characteristics in terms of functional and barrier properties, for example Oxygen Transmission Rate for an oxygen sensitive product. Despite this, the highest risk to pack integrity and shelf life can be failures in the pack heat seals or closures.

    Heat Seal parameters are easily measured; Heat Sealability = Temperature + Pressure + Time. Yet maintaining optimum heat sealing conditions in production and recognising the true cause of poor sealing remains a challenge. Learn More...
