Plastic Grape Preservative UVASYS


The South African plastic grape preservative UVASYS (or sulfur dioxide generator) is an innovation in the field of grape preservatives. It is the only plastic grape preservative with dual release.

Additionally, FAST FRESH is available, a single-release grape preservative for maintaining grapes only during their transportation or for short-term storage. UVASYS VIVO, a dual-release preservative that is fully and immediately recyclable, is also offered, along with the classic paper grape preservative UvasQuality from Chile.


  • Ease of grape box packaging
  • Cost savings due to the elimination of paper packaging materials
  • More uniform and stable distribution of sulfur dioxide in the box Safety: The chemical cannot leak in case the UVASYS is accidentally torn UVASYS can easily be adjusted to fit most boxes
  • Extended storage periods are possible without changing the preservative
  • Consistent aesthetic appearance before and after use
  • Unpacking personnel are never exposed to high levels of sulfur dioxide gas
  • Excellent appearance of stems and cracks
  • Extended shelf life of grapes
  • As the sheets are compressed, they require less storage space
