RF Welding or Sealing of Vinyl Films

What is RF Sealing and Welding?
Radio frequency (RF) welding, also called dielectric welding or high frequency welding, uses electromagnetic energy to generate heat and bond two parts together under pressure. The resulting weld can be as strong as the original material. RF welding is used to bond polymer films for medical, industrial, and consumer products, where a strong or air tight seal is required. Polyvinylchloride (PVC) is the most common thermoplastic to be welded by the RF process. It is also possible to RF weld other polymers including polyurethane, nylon, PET, EVA, and some ABS resins, but special conditions are required.

Our Capabilities:
Over the last 25 years BCW has become known as an expert in RF sealing and welding of flexible and rigid vinyl films. Our RF machines utilize automated indexing systems, turntables, clicker presses, and even multi stage tooling. We have the ability to slit, sheet, screen print, punch, rivet, or insert items, either before or after, the RF operation. We are here to help you with your concept, design, and production needs!

Custom Vinyl Product - Minimums and Limitations:
RF welding requires a tool for each size of a given product. If we do not already have a tool for your specific item, a small investment may be necessary. As a policy, we do not require a minimum order. But, if the requested quantity is too low, the tooling and set-up cost may be prohibitive. Our RF machine limitations are approximately 24" x 32" per impression with films ranging from 4mil to 80mil in thickness.

Examples of Custom Products:
  • Job Ticket Holders
  • Tamper-evident Sleeves
  • Business Card Holders
  • Identification Badge Holders
  • Pressure Sensitive Pouches
  • Other Custom Products
