HELLAGRO plastic grape guards (or sulfur dioxide generating sheets) appeared in the market 20 years ago and have brought a new, highly innovative development in the grape guard sector.
They became the product of choice in many markets and therefore over the years there has been development of competing plastic grape guards. These products are manufactured and printed deliberately to resemble the original. Their performance however is very different. It is the sole plastic grape guard featuring dual release.
In recent years, in order to meet the needs of grape preservation solely during transportation or few day storage, the manufacturer also introduced a product to the market, which features single, rather than dual release of sulfur dioxide.
