There are two conventional stressful problems about the package of zipper bag. One is the difficulty to pick up and to take out just one piece of bag. The other is the uncomfortability of instable opened flap lid. To settle these issues, the package is improved to be able to place vertically instead of horizontally with the lid placed on the top of it. Thanks to the new usable structure, users can take out just one piece easily and the package can be reclosed with the flap lid firmly.
