  • Print Isn’t Dead

    by Emily Walsh August 2017

    Contrary to popular belief, print isn’t dead: at least not printed packaging, an industry growing to a worth of $8 billion of the $20 billion global print market.

    The printed packaging market is booming. As with any growing industry, manufacturers must work vigorously to produce the best product and continue developing better ones.

    Some of the newer developments include smarter surface processes. Que BTG Labs. When it comes to surface processes, we’re in our element. As experts in materials science, we have the ability to optimize critical surface processes for manufacturers—including printed packaging.

    Any printing involves critical surface processes including supplier quality check, surface treatment, verification, shelf life, and trouble shooting.

    The Surface Analyst improves these areas of printed packaging. This surface cleanliness gauge determines the quality of incoming product; sets or optimizes specifications; verifies surface treatments such as corona and flame; determines the shelf life of the material after treatment; and trouble shoots printing issues.

    It’s Opening Day in Cincinnati, Ohio! Now this isn’t just any season opener, Opening Day in Cincinnati is an unofficial city holiday. Downtown is painted red as people gather for the 98th Opening Day Parade and celebrations around town. Offices slow down and desks are empty in schools. Today, Cincinnatians are gearing up for the hometown Reds’ game against the Phillies. We don our red, grab our game day snacks, and pray for fair weather.

  • Food packaging and print industries often face the obstacle of adhering to low energy substrates such as polypropylene. Measuring the surface’s cleanliness prior to bonding or printing is the key to successful adhesion. The common method for measuring surface cleanliness, or surface energy on these materials is dyne inks. However, dyne is highly subjective and requires a skilled technician, and because of its destructive nature, dyne can only be used on a sample rather than an actual material on the assembly line. These downfalls often restrict the use of dyne inks.

    This paper examines the relationship between surface energy and adhesion and how water contact angle provides an accurate and quantitative method for predicting adhesion.  The results of this paper reveal that the Surface Analyst, a handheld water contact angle measurement instrument is an accurate and effective indicator of surface energy. …Read More

    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
