Introduction, Brief Background, and Some Uses of Radiofrequency (RF) Sealers, Heaters, and Gluers
Zory R. Glaser · 1979
The document describes RF sealers, heaters, and gluers operating at 3–100 MHz with most sealers using ISM bands at 13, 27, and 40 MHz, and estimates about 20,000 sealers in use operated by 30 to 40,000 workers.
Plain English Summary
RF sealers, heaters, and gluers are also known as heat sealers, fusers, nolders, fasteners, embossers, high frequency sealers or dryers, electronic or electromagnetic sealers or welders, and dielectric heaters. Most devices operate between 3 and 100 MHz, with sealers commonly using ISM bands at 13, 27, and 40 MHz. An estimated 20,000 sealers are in use operated by approximately 30 to 40,000 workers.
Why This Matters
Dielectric heating can be turned on and off instantaneously, is efficient, precisely controlled, and can heat selected sections of material. Trade associations such as the Binding and Printing Industries of America and the Health Industry Manufacturers Association have concerns about potential changes in RF sealer use. Labor unions including the United Paperworkers International Union and the United Furniture Workers of America have concerns about potential hazards to operators.
