  • New Paper Presented at ANTEC 2017

    by Emily Walsh May 2017

    Last week, BTG Labs exhibited and presented at ANTEC 2017. We were pleased to connect and exchange intelligence with leaders in the plastics industry.

    Our booth featured the Surface Analyst, which uses contact angle to measure surface cleanliness of a material. This monitors the surface preparation process and ensures readiness to bond, print, paint, coat, or seal which can be challenging on plastics. More and more, plastics manufacturers are turning to the Surface Analyst for guaranteeing their surface treatment and final product.

    Along with exhibiting, BTG Labs’ Chief Scientist Dr. Giles Dillingham presented the paper, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance.” The paper explains that the key to manufacturing high performance medical devices is understanding and controlling surface properties. Crucial characteristics of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility depend on only the top few molecular layers of a surface. Dr. Dillingham discusses research done with the Surface Analyst for highly sensitive surface measurements on medical tubing to control coating application. …Read More

  • Surface Analyst Inspecting Film

    Film and Flexible Packaging Applications

    Adhering on film and flexible packaging—whether it’s coating, lamination, metallization, print—can be challenging as the materials generally have very low surface energy, which is difficult to adhere to. So, manufacturers recognize the importance of monitoring and verifying surface treatment. Thus, ensuring a proper in-place surface preparation process and verifying this process is crucial for successful adhesion when working with film and flexible packaging.

    BTG Labs’ Surface Analyst™ is a fast, easy, and accurate surface energy measurement device. Unlike dyne— the most common surface treatment verification method–it is objective, quantifiable, non-destructive to the material being tested and safe for the user. This handheld device allows users to take measurements in under 2 seconds directly on the factory floor. This reduces waste and ensures a successful product and a satisfied customer.

    Typical Surface Analyst Applications in Film and Flexible Packaging Manufacturing

    • Define optimum flame or corona treatment level
    • Verify and monitor flame and corona treatment level
    • Troubleshoot printing and sealing problems
    • Analyze potential migration of low molecular weight components of polymers in packaging
    • Identify and monitor decay of treatment level due to extended storage or storage under non-ideal conditions
    • Verify surface readiness to print on PET and polyethylene bottle packaging
    • Monitor printing film on flexible packaging
    • Flag environmental contaminants in production/on rollers or transfer areas
