摘要： A method and apparatus for making a self-sealable packaging, and the self-sealable packaging and method of use are disclosed. The apparatus includes dispensing a web and converting it by folding or by welding two webs together to provide upper and lower layers defining a pocket therebetween. A line of weakness is provided in an extension on the lower web, and a release liner is positioned over the line of weakness in spanning relationship, with a pattern of adhesive applied between the release liner and the extension below the line of weakness. The release liner is secured to the extension above the line of weakness, and the web is sealed along side boundaries and separated therealong to provide individual bags. The pocket of the bag is sized to receive an article, such as a newspaper therein. After insertion of the newspaper, the extension is separated along the line of weakness to provide a flap carrying the adhesive. The flap is folded over the opening of the pocket to adhesively secure the newspaper therein.
