High-frequency welding for flexible packaging has become a cornerstone for manufacturers seeking reliable seals on pouches. The technology uses electromagnetic waves to generate heat directly within plastic films like PVC and PE, forming strong molecular bonds without glue or mechanical fasteners. This method ensures flexible packaging that withstands pressure, moisture and handling.
Companies turn to high-frequency welding machines for flexible packaging to achieve consistent quality across production runs. The process supports multilayer films common in modern packaging, delivering airtight results that extend shelf life and reduce waste. REG Galbiati srl builds machines that handle these demands, offering precision suited to diverse material thicknesses and formats.
Advantages of HF Technology
Flexible packaging produced through high-frequency welding offers superior seal integrity compared to heat sealing or adhesives, as the fusion occurs at the material’s core. Machines operate efficiently, using targeted energy that minimizes overall power draw and eliminates post-process trimming. Welds remain flexible yet tough, accommodating pouch expansion without cracking.
Process and Machine Features
The high-frequency welding process for flexible packaging begins with feeding film rolls into the machine, where products or fillers are placed between layers. Electrodes apply RF energy, heating the interface to fuse materials seamlessly. Key features in REG Galbiati machines include adjustable power from 6-20 kW, pneumatic presses for even pressure and digital controls for recipe storage.
These elements allow customization for different pouch sizes and film gauges, ensuring uniform seals on complex shapes. Safety interlocks and cooling systems maintain operator protection and continuous operation. The result is flexible packaging ready for immediate use, with clean edges and no residue.
