At the heart of our business lies a commitment to innovation, service excellence, and a relentless pursuit of creating value for our clients. Today, we want to share a powerful example of our recent collaboration with a prestigious machinery manufacturing company in China, which is renowned for its impressive line of machinery including lamination machines, bubble film machines, wrapping film machines, and no-soil layer machines.
Our client, a name synonymous with industry-leading machinery production, required an upgrade to their lamination machine units. Their primary concern was improving the adhesion and print quality on the cast film used for the interior lining of kraft paper bags. This is where our Corona treatment machines came into play.

The client’s lamination machines specialize in producing films for a wide range of applications. However, producing cast film for kraft paper bag interiors presented unique challenges. The film required excellent adhesion properties to ensure that it sticks perfectly onto the bag, ensuring durability and structural integrity.
Understanding these specific requirements, we provided two 20KW Corona treatment units along with high-speed corona stands, which were seamlessly integrated into their existing lamination machine units. The Corona treatment method, renowned for its ability to improve adhesion on polymers, proved to be an optimal solution.
Our Corona treatment machines work by bombarding the film surface with high voltage, leading to oxidation and roughening of the surface at a micro-level. This increases the surface tension of the polymer film, resulting in improved adhesion when the film is later coated or laminated, which was the primary requirement for the client’s kraft paper bag production line.
After the successful installation and operation of our Corona treatment units, the client reported substantial improvements in the quality of their coated films. Not only did the films exhibit enhanced adhesion, but they also demonstrated superior printability, another critical aspect for the aesthetic appeal of kraft paper bags.

This collaboration stands as a testament to our capacity for providing bespoke solutions tailored to specific industrial needs. As the leading manufacturer of Corona treatment machines in China, we understand the unique challenges of various industries and are ready to provide effective and innovative solutions.
Furthermore, by sharing our insights and achievements, we aim to shed light on the importance of Corona treatment in the field of film production and inspire more industries to reap its benefits. With our cutting-edge technology and commitment to excellence, we remain your partner of choice in mastering Corona treatment solutions.
We hope this article provides valuable insights into our client collaborations and our commitment to advancing the industry. We welcome any further questions and discussions. Remember, when it comes to improving the quality of your products, we’re here to help.
