Matesa’s Grape guard
Paper device coextruded with physical barriers, conforming cells containing sodium metabisulphite. This element in the presence of humidity generates sulphurous anhydride, element which inhibits the growth of the Botrytis cinerea fungi.

Device formed by two paper barriers with polyethylene plus another of Kraft paper, the generator surface presents small cells which contain the active ingredient sodium metabisulphite (Na2S2O5) that in contact with humidity generates sulphurous anhydride (S02), gas which inhibits the development and growth of fungi, avoiding infection through Botrytis cinerea pers. in table grape during refrigerated packaging and transport.
Two phases device formed by a polypropylene barrier, a mid sheet of paper with polyethylene on both sides and an inferior barrier of brown Kraft paper, the generator surface presents small cells which contain the active ingredient sodium metabisulphite (Na2S2O5) that in contact with humidity generates sulphurous anhydride (S02), gas which inhibits the development and growth of fungi, avoiding infection through Botrytis cinerea pers. in table grape during refrigerated packaging and transport.
One phase emission device (slow phase) formed by two paper barriers with polyethylene that presents small cells which contain the active ingredient sodium metabisulphite (Na2S2O5) that in contact with humidity generates sulphurous anhydride (S02), gas which inhibits the development and growth of fungi, avoiding infection through Botrytis cinerea pers. in table grape during refrigerated packaging and transport.
One phase device formed by two paper barriers with polyethylene which contains the active ingredient sodium metabisulphite (Na2S2O5), between the papers. This in contact with humidity generates sulphurous anhydride (S02), gas which inhibits the development and growth of fungi, avoiding infection through Botrytis cinerea pers. in table grape during refrigerated packaging and transport
Device that generates S02 in the bottom part of the box, assuring gas concentration on the most sensitive points to the presence of Botrytis.
