Household vacuuming systems require special film and bags with a structure on the inside to enable air extraction. The high-quality ROMMELSBACHER film bags and film rolls are made of patented 2-layer material and have a very special corrugation that ensures extremely good suction performance. The material is BPA-free, resistant to heat and cold and very suitable for sous vide cooking. The bags are extremely stable and robust so that they can be cleaned (even in the dishwasher) and reused many times. The very high product quality ensures the best vacuuming properties and long-term, sustainable use. For this reason, we recommend the use of original ROMMELSBACHER accessories for our appliances, as this is the only way we can be sure that all components work together for an optimum vacuuming process.
