In addition, within the package, the absorbent articles may be damaged when an external force is applied thereto during storage and transportation thereof. The individually packaged absorbent articles in the packaging bag may be deformed due to the external force applied to the bag.
People tried to overcome above mentioned problems. For that reason, line of perforations are used in the packaging film which circumscribs partially or entirely one side of the package, to facilitate opening of the package. But in that case, when the diaper package is opened once, it can not be reclosed.
JP04532154 relates to a diaper packaging body having slip resistant strips attached to the front and back end edges are in contact with and releasably engaged with each other. The application provides a solution about preventing the shape of the diapers in the package. Therefore, anti-slip sheet is mounted on front and rear ends of the closure. But the closure is not very effective to hold the diapers together in their desired shape. Because there still remains free spaces in tha package that allows moving of the diapers freely. And as a consequence the shapes of the diapers may not be protected and the folding may be deformed.
US9393161 relates to a package containing disposable diapers having reclosable zip-lock components and a handle cut. This application enables the package to be recloseable compressed in stacks that are roughly block-shaped, which are then enclosed in retail packages formed of polymer film. But when the packages are transported or placed on the market shelfs they can be deformed in the single zip- locked package. Because there will be again free spaces that will allow freely moving of the articles.
