Plasma surface treatment can be used to improve the adhesion of glue and other adhesives in folder gluer machines. Folder gluers are used in the packaging industry to fold and glue corrugated boxes and other types of packaging materials.
In folder gluer machines, it is essential to have strong adhesion between the glue and the substrate to ensure the final product is strong and durable. However, some substrates may have low surface energy or other properties that make it difficult for the glue to adhere properly. Plasma surface treatment can be used to modify the surface properties of the substrate, making it more receptive to the glue and improving the strength and durability of the final product.
Plasma surface treatment involves exposing the substrate surface to a low-pressure plasma. The plasma generates a range of reactive species such as ions, radicals, and photons that can modify the surface chemistry of the substrate. This modification can improve the surface energy and wettability of the substrate, making it more receptive to the glue and other adhesives.
Plasma surface treatment can be used on a variety of substrates, including paperboard, corrugated board, and plastics. The treatment can be applied directly to the substrate surface in-line with the folder gluer machine, which allows for fast and efficient processing.
One of the advantages of plasma surface treatment is that it is a non-contact process that can be performed at ambient temperature and pressure, making it a convenient and cost-effective method for improving adhesion in folder gluer machines. Additionally, the process does not require any additional chemicals or solvents, which can be harmful to the environment.
Overall, plasma surface treatment is a valuable technique for improving the adhesion of glue and other adhesives in folder gluer machines, which can result in stronger and more durable packaging products.
