A thin film is applied to a substrate material to improve its strength, durability, and resistance to moisture or other environmental factors. Corona treatment is a valuable tool for film lamination, as it can improve adhesion, increase productivity, improve quality, and offer greater versatility in substrate selection.
Corona treatment improves surface wettability, which leads to better coverage and uniformity of coatings. This results in higher quality coatings that are more visually appealing and have better performance characteristics.
When splicing, it is important that the material passes through the corona treater without being damaged or wrinkled. If the material is not properly guided or controlled, it can cause problems such as web breaks, which can lead to downtime and increased waste. QC equipment features counter-weighted swinging assemblies paired with pneumatics for splice detection.
