In today’s packaging industry, quality and aesthetics go hand in hand. Products must not only be well protected but also visually appealing. To meet these expectations, manufacturers are increasingly adopting high-frequency (HF) welding — a technology that guarantees precision, strength, and consistency in every seal. REG Galbiati, with over 70 years of experience, offers cutting-edge HF welding machines.
The role of welding in modern packaging
The packaging industry has evolved rapidly, driven by consumer expectations, safety regulations, and sustainability goals.
Traditional sealing techniques, such as heat sealing or gluing, often present issues like:
- Inconsistent sealing quality,
- Material distortion,
- Excess adhesive usage,
- Limited production speed.
High-frequency welding eliminates these limitations.
How high-frequency welding works
High-frequency welding uses electromagnetic energy to generate heat directly inside thermoplastic materials such as PVC, PET, and PU films. When exposed to high-frequency waves, the molecules within the material vibrate and generate heat from the inside, creating a homogeneous molecular bond between layers.
This process ensures:
- Perfectly sealed edges without deformation,
- Uniform pressure distribution,
- Enhanced visual appeal, with clean, invisible joints.
Benefits of HF welding for the packaging industry
- Precision and Repeatability. HF welding delivers exceptional accuracy. Each seal is identical, ensuring consistent results even in large-scale production.
- Superior Strength and Safety. The molecular bond formed during HF welding ensures leak-proof seals.
- Aesthetic Finish. Since the heat is generated internally, external surfaces remain smooth and undamaged. The result: perfectly sealed, visually appealing packaging.
- Faster Production. Cycle times are shorter than with traditional heat-sealing systems. Automation options make HF welding an ideal choice for high-volume manufacturing.
