high frequency welding of pvc & Pu


Joining PVC and PU film using high frequency welding creates a strong, secure seal.


High Frequency (HF) welding is a method of joining plastic film together using an electromagnetic field coupled with pressure in order to create a tight seal.

The High Frequency (HF) welding process involves electrical energy causing the molecules within the PVC and PU film to move around, generating heat and softening the material so that it begins to fuse together. Once cooled, the HF-welded surfaces become completely fused together, creating an extremely strong join.

HF Welding Applications

We produce PVC & PU gas sample bags using High Frequency (HF) welding. The secure HF bonding creates an airtight environment, providing low permeation of other gases into the bag and enabling the sample to remain uncontaminated. Find out more about our PVC & PU Gas Sample Bags.

Thanks to the high frequency welding process enabling the plastic to be flexible, we also create bespoke 3D shapes of every possible size and shape. Both reusable and easily cleanable, these custom fabrications protect critical environments from contamination.
