High-Frequency Welding for Flexible Packaging

High-Frequency Welding for Flexible Packaging

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.

High-Frequency Welding for Blister Packaging Machines

High-Frequency Welding for Blister Packaging Machines

High-frequency welding stands out as a key technology for creating blister packaging that combines strength, protection and visual appeal. This process uses electromagnetic energy to weld plastic materials, producing solid and durable blister packs suitable for a wide range of non-food products that must be protected during handling, transport and display. REG Galbiati develops high-frequency welding machines for packaging that enable the creation of blisters designed to keep products intact and well protected throughout their lifecycle, while enhancing their attractiveness on the shelf.​

REG Galbiati crafts machines that produce solid, durable blisters that meet the specific requirements of each customer in terms of format, productivity and quality. This technology helps achieve reliable, repeatable welds and supports efficient production processes, reducing the risk of defects and ensuring consistent performance over time.​

Key Benefits for Blister Packaging

Blister packs made with high-frequency welding offer high mechanical resistance in the welded areas, reducing the risk of accidental opening or damage during logistics and display. The quality of the weld contributes to maintaining product protection and to presenting the contents in a clear and orderly way, supporting brand image and perceived value.​

How the HF Welding Process Works

In high-frequency welding for blister packaging, the materials to be joined are placed between electrodes that generate an electromagnetic field. The high-frequency energy produces heat inside the plastic material, allowing the layers to weld together in a controlled way and creating a strong and durable joint. REG machines are designed to manage the welding parameters according to the type of material and application, helping to obtain uniform, repeatable results and high productivity.​

Real-World Applications and Innovations

REG high-frequency welding machines for blister packaging are designed to produce solid and durable packs that keep products intact and well protected throughout their lifecycle. Thanks to the high-frequency process, the welded areas offer excellent mechanical resistance, making the blisters suitable for products that must withstand handling, transport and display without risking accidental opening or damage. These solutions are used in the packaging of a wide range of non-food products, where protection, resistance and attractiveness are key to standing out on the shelf and supporting brand image. By combining high-frequency welding with tailored tooling and process parameters, REG systems help manufacturers create packaging that matches their production needs in terms of format, productivity and quality requirements, while maintaining reliable and repeatable results over time.​
