A chlorine generator for preserving fruits and vegetables includes a first layer of paper or polyethylene and a second layer of polyethylene. The first layer has a weight of from about 20 to about 70 g/m2 and is preferably made from a laja-type paper. It is preferred that at least one surface of the first layer is coated with a plastic permeable film, such as polyethylene, having a weight of from about 5 to about 25 g/m2. The two layers are joined together, preferably by thermal seal, to define one or more pockets. A hypochlorite material, such as calcium hypochlorite, is placed in the pockets. This material releases active chlorine gas upon reaction with moisture from said fruits and vegetables. Alternatively, the first layer can be impregnated with a mixture containing the hypochlorite (such as a mixture of hypochlorite and sodium chloride) and is preferably coated with a resin material. |
