Packaging bags

Abstract

This article is a packaging bag. As shown in the "reference rear perspective view," the lid has a first sealing adhesive tape, a reinforcing tape, and a second sealing adhesive tape provided parallel to the folding edge along which the lid is folded toward the bag body. Perforations extending parallel to the folding edge are provided between the first sealing adhesive tape and the reinforcing tape, and between the second sealing adhesive tape and the reinforcing tape. A tear-off section with reinforcing tape is formed between the two perforations. The tear-off section is reinforced with reinforcing tape to prevent it from tearing along the direction of the perforations. After placing contents in the bag body, the release paper from the first sealing adhesive tape is removed, and the lid is folded back at the folding edge while leaving the release paper from the second sealing adhesive tape intact, and then adhered to the bag body with the first sealing adhesive tape. This seals the bag body with the lid, as shown in the "reference perspective view showing the first state of use." In the sealed state shown in the "reference perspective view showing a first state of use," the tear-off portion is separated from the lid along the perforation, separating the lid into a first lid piece adhered to the bag body with a first adhesive sealing tape and a second lid piece provided with a second adhesive sealing tape, as shown in the "reference perspective view showing a second state of use," and the bag body is opened. In the opened state of the bag body shown in the "reference perspective view showing a second state of use," after contents are placed in the bag body, the release paper of the second adhesive sealing tape is removed, the second lid piece is folded back at the fold edge, and the second lid piece is adhered to the bag body with the second adhesive sealing tape. This seals the bag body with the second lid piece, as shown in the "reference perspective view showing a third state of use."
