INTEROX® AG Spray 35 is a clear, colorless liquid which is a specially designed hydrogen peroxide grade, used in aseptic packaging process using spray technology. Spray technology e.g. in Combibloc aseptic packaging machines, where the hydrogen peroxide (35% w/w) is typically heated to 90-200oC to form a spray which is applied to the performed packs (paperboard / aluminium / plastic composite or PET/PE containers). The packs are dried using hot air before being filled with beverage or food product and heat sealed. In this case, the hydrogen peroxide solution is continually replaced. The intension of aseptic packaging is the filling of beverages or liquid foods such as soups into paperboard or plastic containers under aseptic conditions in order to conserve the shelf-life of the packaged products. Hydrogen peroxide’s density is slightly higher than that of water, but is miscible with water in all proportions. It decomposes exothermally to water and oxygen. The decomposition is naturally slow (<1% per year), but is accelerated by heat and decomposition catalysts, such as transition metals and their compounds, strong acids and strong alkalis.
