Verpackungsmaterial und seine Anwendung. |
摘要 |
The present invention relates to a packaging material for reduced transfer from a package to its content of substances causing undesirable taste and/or hazardous substances, this reduction being due to the packaging material containing a hydrophobic zeolite. More specifically, the invention concerns paperboard, in which case the substances causing undesirable taste mainly are naturally occurring extractive substances, oxidation products thereof and, to a lesser extent, the paper chemicals present. Further, the presence of a hydrophobic zeolite in the paperboard enhances the water-repellent (hydrophobic) capacity. Also, the present invention concerns a method for production of a packaging material of paper, board or paperboard by forming and dewatering a suspension of lignocellulose-containing fibres, where the dewatering takes place in the presence of a hydrophobic zeolite. Moreover, the present invention relates to the use of a hydrophobic zeolite for production of a packaging material, as well as the use of the thus-produced packaging material in packages for solid or liquid foodstuff, tobacco or medicines. |
