Several bonding methods for joining or sealing plastic medical devices are available on the market, such as adhesives, hot plates, or ultrasonics. The laser welding process offers many performance advantages over these traditional plastic welding techniques. The availability of low-cost, reliable lasers with fiber optic output means that laser welding can be a precise, flexible, and cost-effective tool.

Moreover, laser welding is a clean technique with no consumables or hazardous chemicals that could require special handling. There are no glue, fumes or solvents to deal with, and laser welding generates no particulates that would need careful cleaning after bonding. Plus, there are no glue nozzles to clean or replace. Not having to deal with hazardous chemicals for processing or cleaning contributes to the growing of this green sealing method for the medical field.
