The RF sealing process is also known as dielectric sealing, RF welding, and heat sealing, among many others. All of the various names describe the same high-tech method of joining thermoplastic films using Radio Frequency (RF) energy. First, RF waves excite the molecules of materials. Next, they are joined together from the inside out, fusing the materials. No matter your application, an RF seal is reliable; and won’t leak either air, moisture, water, or fuel.
