Each has a glue-free portion, and the sealing portion and the hot-melt adhesive portion of the packaging bag are folded and bonded to the back portion to close the opening of the storage space, and both ends of the hot-melt adhesive portion are blocked by the glue-free portion. Therefore, it is possible to prevent the two ends of the hot melt adhesive from sticking to other surrounding packaging bags, and it is more convenient for packaging and use, and the packaging bag is suitable for automatic sorting and transportation of general express articles.

In order to achieve the above object, the presently-applied packaging bag includes a bag body and a hot-melt adhesive portion, wherein: the bag body has front and rear opposite front and back portions to surround the upper and lower seals. The side of the storage space, and the front portion extends upwardly from the sealing portion; the hot melt adhesive portion is attached to the back surface of the sealing portion of the packaging body to form a long-shaped hot melt adhesive surface extending laterally. The hot melt adhesive surface is covered with a release paper sheet, and the sealing portion has a glueless portion between the opposite sides and the hot melt adhesive surface, respectively, and the sealing portion and the hot melt adhesive portion of the packaging bag body are folded. Adhered to the back portion to open the upper part of the storage space, and both ends of the hot melt adhesive portion are blocked by the glue-free portion of the sealing portion.

In the above-mentioned adhesive-type packaging bag, the two ends of the release paper sheet respectively extend beyond the hot melt adhesive portion.

In the above-mentioned adhesive-type packaging bag, the two ends of the release paper sheet are respectively aligned with the opposite sides of the sealing portion.

In the above-mentioned adhesive-type packaging bag, the opposite sides of the sealing portion of the packaging bag body and the two ends of the release paper sheet may be beveled or straight.

For the purpose of achieving the above objectives, the technical means and its effects, the following is a description of the possible embodiments, and the following diagrams are described as follows: First, please refer to the third to seventh figures, which can be clearly seen from the figure. It can be seen that the self-adhesive packaging bag of the present invention is suitable for the packaging of goods for express articles, and the plastic packaging bag comprises a bag body 1, a hot melt adhesive portion 2 and a release paper sheet 3, wherein: the bag body 1 can be made of a plastic material, and the package body 1 has front and rear facing portions 11 and a back portion 12 to surround the storage space 15 having the upper opening 13 and the lower sealing edge 14, and the front portion 11 extends upwardly. Shaped seal 16 and sealed The hinge 16 has two opposite sides 161.

The hot melt adhesive portion 2 is attached to the back surface of the sealing portion 16 of the package body 1 by a hot melt blasting method to form a long-length elongated hot melt adhesive surface 21, and the two ends 22 of the hot melt adhesive surface 21 are close to each other. At the opposite side edges 161 of the sealing portion 16, the sealing portion 16 has a glueless portion 162 between the opposite side edges 161 and the two ends 22 of the hot melt adhesive surface 21, respectively.

The release paper sheet 3 is placed on the hot melt adhesive surface 21, and the two ends of the release paper sheet 3 respectively extend beyond the two ends 22 of the hot melt adhesive portion 2, and the two ends of the release paper sheet 3 are respectively aligned with the sealing portion 16. The two opposite side edges 161, and the opposite side edges 161 of the sealing portion 16 and the ends of the release paper sheet 3 are beveled.

When the gel-filled packaging bag of the present invention is in use, an article (not shown) is placed in the storage space 15 from the opening 13 above the packaging bag body 1, and then the release paper sheet 3 is torn off, and then the packaging bag body 1 is removed. The sealing portion 16 and the hot melt adhesive portion 2 are folded and adhered to the back surface portion 12 to close the opening 13 of the storage space 15, and the two ends 22 of the hot melt adhesive portion 2 are respectively received by the glueless portion 162 of the sealing portion 16. The barrier can prevent the two ends 22 of the hot melt adhesive surface 21 from sticking to other surrounding bags for more convenient use, and the packaging bag is suitable for automatic sorting and transportation of general express items.
