The invention relates to a package for a sterilised disposable article, the package having opposing base materials bonded together along marginal portions by a heat sealed adhesive and peelable apart to open the package. One of the base materials is paper which has been neutrally sized to prevent absorption of the adhesive. The outer surface of the paper is preferably machine glazed for porosity and pore size control. The adhesive may be applied all over the unglazed surface of the paper but in a discontinuous form to permit passage of a sterilising gas into the sealed package.
