押しつけて貼り付け、閉封する。If the item is half or less than the height of the bag, fold the bag in front as shown in FIG.
The adhesive layer 3 of the flap is pressed against the lowermost adhesive layer 3n of the front body portion, adhered, and closed.

【００２０】このように、本発明の袋では中に入れる品
物の大小に応じてフラップの接着剤層を前胴部の所要の
接着剤層へ貼り付けて、品物を体裁よく包装できる。As described above, according to the bag of the present invention, the adhesive layer of the flap is stuck to the required adhesive layer of the front body according to the size of the article to be put therein, and the article can be packaged in a good format.

ブロッキングを防止できる。Each adhesive layer is made pressure-sensitive and adheres to each other by the adhesive layers. However, when the adhesive layers do not adhere to each other, the adhesive layers do not adhere to each other. Even if the bags are stacked with the (or back body) facing upward, the bags do not adhere to each other, and blocking of the bags can be prevented.

【００２２】また、フラップの粘着剤層を剥離紙で被覆
