Capping machines are devices used in the packaging industry to securely seal containers, such as bottles and jars, with caps. They ensure that products remain fresh and safe from contamination. These machines can handle various cap types, including screw caps, snap-on caps, and corks, making them versatile for different products. Typically found in factories, capping machines can be manual, semi-automatic, or fully automatic, depending on production needs. They are often integrated into production lines alongside other equipment like filling machines and labeling machines to streamline the packaging process and improve efficiency.
