Ultrasonic Tube Sealer

An ultrasonic tube sealer is a packaging machine that seals soft tubes using high-frequency ultrasonic vibration instead of traditional external heating. During the sealing process, ultrasonic energy generates internal friction within the tube material, causing it to melt and bond precisely at the sealing area.

Working Steps of Ultrasonic Tube Sealer

1. Positioning

The tube is accurately positioned and aligned in the sealing station.

2. Filling

The product (cream, adhesive, paint, etc.) is filled into the tube automatically.

3. Sealing

The tube tail is sealed using ultrasonic technology.

4. Trimming

Excess tube material is trimmed to ensure a clean and consistent appearance.

Benefits of Ultrasonic Sealing Technology

Sealing Consistency

Ultrasonic sealing maintains consistent performance even with product residue at the tube tail, reducing leakage and defects.

Product Protection

Internal, localized heat prevents thermal damage to sensitive formulations, protecting product integrity and avoiding ingredient degradation.

Premium Appearance

Flat, smooth, and uniform tube seals create a clean and attractive appearance, enhancing shelf appeal.

  • The DGF-25C ultrasonic tube sealer delivers strong, clean, and uniform seals for cosmetic creams and liquid or semi-liquid products. Using ultrasonic sealing technology, it eliminates tube deformation, reduces material waste, and ensures a professional finish—ideal for modern cosmetic, industrial, and pharmaceutical production.
