The machine typically works by heating the open end of the tube and then applying pressure to create a strong, uniform seal. Depending on the model, it can handle different types of plastics such as PE, LDPE, and laminated tubes. Advanced models may include functions like automatic tube loading, orientation, filling, coding, and trimming for high production efficiency.

Key features usually include:

Precise temperature control to ensure high-quality sealing.

Adjustable sealing speed to match production needs.

Clean and professional finish, often with optional date or batch coding.

Durable construction for long-term industrial use.

Overall, a plastic tube sealing machine improves packaging quality, extends product shelf life, and enhances production efficiency.
