What Is a Manual Tub Sealing Machine?
A Manual Tub Sealing Machine is a semi-automatic packaging device that applies a sealing film onto the tops of tubs, containers, or cups. Unlike fully automatic systems, it requires minimal manual input — making it ideal for small-scale operations, startups, and businesses with moderate production volumes.
The machine uses heat and pressure to bond a foil or film seal onto the container’s rim, ensuring airtight protection and tamper-evident security.
