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
A world leader in flexible film packaging was frustrated with their inefficient surface processes and desired a fast, easy, quantitative, and objective method to accurately measure their surfaces. Their in-place method included dyne inks to measure corona treatment on films. However, they found dyne to be too subjective, inaccurate, and inefficient as it could not come in contact with the actual material because of its destructive nature. And alarmingly, it was dangerous to the user.
The manufacturer required a way to ensure that the corona treatment would lead to successful coating, laminating, or metallization. They needed to reduce failures, waste, and produce a product that would offer the customer a stronger, more reliable product.
BTG Labs’ Surface Analyst brought the answer to this dilemma. It replaced dyne as a more accurate, easier to use, and safer surface measurement device. It also provided quantifiable measurements that could be used for R & D work and to report to their quality control process to the customers. The Surface Analyst, which uses only highly purified water gave the manufacturer the ability to measure on the actual material and did not pose a threat to the user. Thus, their assembly process became quantifiable and more efficient.
