[0030] Hereinafter, the plastic film bag of the embodiment of the present invention will be described in detail based on the drawings. However, the plastic film bag of the present invention can be embodied in various ways and is not limited to the embodiments described in this specification. This embodiment is provided for the purpose of enabling those skilled in the art to fully understand the invention by making the disclosure of the specification sufficient.

[0031] Figure 1 This shows the front view of the plastic film bag 1 of an embodiment of the present invention, Figure 2 and shows the back view. The plastic film bag 1 of the present embodiment includes a front surface A, a back surface B, and side enclosures C provided on the left and right. The front surface A and the back surface B are plastic films in a substantially rectangular shape. The side enclosures C are plastic films that are continuously and concavely folded with the front surface A and the back surface B. The bottom D of the plastic film bag 1 is sealed by heat sealing. The upper end portion of the plastic film bag 1 is not heat-sealed and is used as the bag opening E.

[0032] As Figure 1 shown, the plastic film bag 1 of the present embodiment includes a tape 18 such as a tape for closing the bag opening E (refer to Figure 3The upper part 11 for attachment, the label attachment part 12 for attaching a label, and the main body part 13. The upper part 11 and the label attachment part 12 can be separated from the main body part 13 by the cutting lines 15, 16, and 17.

[0033] On the upper part 11 of the plastic film bag 1, marks 11a (such as characters, solid lines, arrows, dotted lines, etc.) indicating the attachment position of the belt 18 are depicted by printing or the like. The mark 11a is depicted on the front surface A of the plastic film and also on the back surface B. When closing the bag mouth E, the upper part 11 is folded back in a convex manner, and the belt 18 is attached to the folded part (see Figure 3 ).

[0034] Below the upper part 11, a label attachment part 12 is provided, and a label printed with the name of the recipient, barcodes, etc. is attached to the label attachment part 12. The label attachment part 12 is continuous with the upper part 11, and no cutting line is provided between the upper part 11 and the label attachment part 12. On the label attachment part 12, marks 12a (such as characters, graphics, etc.) indicating the attachment position of the label are depicted by printing or the like.

[0035] The cutting line 15 on the front surface A of the plastic film bag 1 crosses the front surface A and has a concave part 15a. The concave part 15a of the cutting line 15 locally surrounds the label attachment part 12. In the present embodiment, three sides of the substantially rectangular label attachment part 12 are surrounded. The cutting line 15 delimits the boundary between the upper part 11 and the label attachment part 12 and the main body part 13.

[0036] As Figure 2 shown, the cutting line 16 on the back surface B of the plastic film bag 1 crosses the back surface B and has a concave part 16a. The concave part 16a of the cutting line 16 locally surrounds the part 14 corresponding to the label attachment part 12 on the front surface A. In the present embodiment, three sides of the substantially rectangular part 14 are surrounded. The cutting line 16 determines the boundary between the upper part 11 and the corresponding part 14 and the main body part 13.

[0037] On the side circumference C of the plastic film bag 1, a linear cutting line 17 continuous with the cutting lines 15 and 16 on the front surface A and the back surface B is provided.

[0038] The cutting lines 15, 16, and 17 surround the periphery of the plastic film bag 1 in a ring shape. The cutting lines 15, 16, and 17 are provided, for example, by pressing a perforating tool against the plastic film bag 1.

[0039] As Figure 3 shown, when using the plastic film bag 1, items such as a suit and small objects are put in from the bag mouth E, the upper part 11 is folded back in a convex manner, and the belt 18 is attached to the upper part 11. Thereby, the bag mouth E can be closed. Then, a label (not shown) is attached to the label attachment part 12.

[0040] As Figure 4As shown, when opening the plastic film bag 1, firmly grasp and pull the label attachment part 12 on the surface A and the corresponding part 14 on the back B of the plastic film bag 1 with your hand. Then, the upper part 11, the label attachment part 12, and the corresponding part 14 are separated from the main body part 13 along the cutting lines 15, 16, and 17. Since the tape 18 and the label are attached to these separated parts 11, 12, and 14, they cannot be reused. However, the main body part 13, which accounts for more than 60% of the whole, can be reused.

[0041] Again, as Figure 1 shown, patterns 19 are depicted on the main body part 13 and the upper part 11 on the surface A of the plastic film bag 1 by printing or the like, and these patterns 19 interfere with reading the barcodes of the items placed in the plastic film bag 1.

[0042] As described above, barcodes are attached to the labels. Barcodes are also attached to the items inside the plastic film bag 1. Therefore, even if one wants to use a reading device to read the barcode on the label, it is possible to read the barcode of the item inside the plastic film bag 1. To prevent this, the patterns 19 are provided. The patterns 19 reflect the red light emitted by the LED and laser diode of the reading device, making it impossible to read the barcode of the item inside the plastic film bag 1.

[0043] The color of the patterns 19 is preferably white. This is because it can reflect the red light emitted by the reading device well, making it impossible to read the barcode of the item inside the plastic film bag 1. When the patterns 19 are of a red color system, the red light emitted by the reading device can pass through, so the barcode of the item inside the plastic film bag 1 will be read. When the patterns 19 are of a black color system, the reused plastic film bag 1 will turn black, making it difficult to confirm the inside.

[0044] The shape of the patterns 19 is not particularly limited. For example, it is a shape in which small quadrilaterals and large quadrilaterals are alternately arranged vertically and horizontally. The shape of the patterns can also be a water droplet pattern or the like.

[0045] The material of the plastic film bag 1 is not particularly limited. For example, it is polyethylene, polypropylene, polystyrene, recycled resin raw material, etc. The recycled resin raw material refers to recycling waste plastic film bags and other waste plastics, crushing and cleaning them, and using an extruder to make recycled resin pellets. To achieve the SDGs, it is preferable to use recycled resin raw material.

[0046] The color of the plastic film bag 1 is not particularly limited. To be able to confirm the items inside, it is preferably semi-transparent or transparent.

[0047] The manufacturing method of the plastic film bag 1 is not particularly limited. For example, side enclosures C are formed on the left and right of a tubular plastic film, bottom sealing is performed at a specified bag length interval, and then cutting is performed at a specified bag length interval, whereby the plastic film bag 1 can be manufactured.

[0048] The above has described the structure of the plastic film bag 1 of the present embodiment. According to the plastic film bag 1 of the present embodiment, the following effects are achieved.

[0049] The upper part 11 to which the tape 18 for closing the bag mouth E is attached and the label attachment part 12 for attaching a label can be separated from the main body part 13 by the cutting lines 15, 16, 17. Therefore, even if a label and the tape 18 are attached, the plastic film bag 1 can be reused.

[0050] Since the concave portions 15a, 16a are provided in the cutting lines 15, 16 on the front surface A and the back surface B of the plastic film bag 1, the label attachment part 12 on the front surface A and the corresponding part 14 on the back surface B corresponding to the label attachment part 12 can be firmly grasped by hand to open the plastic film bag 1. Therefore, the opening operation becomes easy.

[0051] Since the mark 11a indicating the attachment position of the tape 18 is depicted on the upper part 11 of the plastic film bag 1, the tape 18 can be attached so as not to contact the cutting line 15 on the front surface A.

[0052] Industrial applicability

[0053] The use of the plastic film bag 1 of the present embodiment is not particularly limited, and it is suitable for mailing and express delivery of items such as suits and small items. Since a barcode can be printed on the label, it is particularly suitable for use as a delivery bag when a clothing manufacturer delivers items to a mass retailer. If the barcode is read, mailing and express delivery from the logistics center of the mass retailer to each store become easy.

[0054] It should be noted that the present invention is not limited to being embodied as the above embodiment, and can be embodied as other embodiments within the scope of not changing the gist of the present invention.

[0055] In the above embodiment, side circumferences are provided on the left and right of the plastic film bag, but side circumferences can also be provided at the bottom, or the left and right side circumferences can be omitted.

[0056] This specification is based on Japanese Patent Application No. 2023-199928 filed on November 27, 2023. The entire content is incorporated herein.
