The liner biocides include 5-chloro-2-methyl-4-isothiazolin-3-one, hypochlorite and sodium hydroxide and sodium bromide. A fluted medium is sandwiched between the single and double face liners with an adhesive that is produced with diluted starch and to which biocides have also been added. The biocides in the adhesive include 1,2-benzothiazol-3(2H)-one and poly[oxyethylene(dimethyliminio)ethylene dichloride].
