Description

[Technical Field]

[0001] The present invention relates to a recyclable plastic film bag. [Background technology]

[0002] In order to achieve the SDGs (Sustainable Development Goals), plastic film bags that have been used and discarded are being recycled. For example, Patent Document 1 discloses that waste plastics such as waste plastic film bags are collected, crushed and washed, and turned into recycled resin pellets using an extruder, and plastic film bags are recycled from the recycled resin pellets (see Patent Document 1).

[0003] Generally, plastic film bags are strong, lightweight, waterproof, and easy to use. For this reason, plastic film bags are often used rather than cardboard boxes when mailing or delivering items such as clothes and small items. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 7-903 Summary of the Invention [Problem to be solved by the invention]

[0005] However, labels printed with addresses, barcodes, etc. are affixed to plastic film bags used for mailing and home delivery. Furthermore, to close the opening of the plastic film bag, tape such as packing tape is affixed to the top of the bag. Because these labels and tapes are sometimes made of paper, there is a problem in that plastic film bags with labels and tapes affixed cannot be recycled.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a plastic film bag that can be recycled even if a label and tape are attached. [Means for solving the problem]

[0007] In order to solve the above problems, one aspect of the present invention is a plastic film bag in which an upper portion to which a tape for closing the bag opening is attached and a label attachment portion to which a label is attached can be separated from a main portion by a tear line. The plastic film bag has a pattern printed on the main body portion on the front side of the plastic film bag that prevents the barcode of an item placed in the plastic film bag from being read. Another aspect of the present invention is a plastic film bag in which an upper portion to which tape for closing the bag opening is attached and a label attachment portion to which a label is attached can be separated from a main portion by a perforation line, and the perforation line on the front of the plastic film bag crosses the front and has a recess that partially surrounds the label attachment portion, and the perforation line on the back of the plastic film bag crosses the back and has a recess that corresponds to the label attachment portion and partially surrounds the portion where the label is not attached. [Effects of the Invention]

[0008] The present invention One aspect of According to the FDA, plastic film bags can be recycled even with labels and tape attached. It is also possible to prevent the barcodes of the articles placed in the plastic film bags from being read. According to another aspect of the present invention, plastic film bags can be recycled even when labels and tape are attached. Furthermore, the plastic film bags can be opened by firmly grasping the areas corresponding to the label attachment areas on the front and back of the bags with the hands, making the opening process easier.

[0010] Hereinafter, a plastic film bag according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the plastic film bag according to the present invention can be embodied in various forms and is not limited to the embodiments described herein. The present embodiment is provided with the intention of enabling those skilled in the art to fully understand the invention by providing sufficient disclosure in the specification.

[0011] FIG. 1 shows a front view of a plastic film bag 1 according to one embodiment of the present invention, and FIG. 2 shows a back view. The plastic film bag 1 of this embodiment has a front A, a back B, and gussets C on the left and right sides. The front A and back B are made of approximately rectangular plastic film. The gusset C is a valley-folded plastic film that is continuous with the front A and back B. The bottom D of the plastic film bag 1 is sealed by heat sealing. The upper end of the plastic film bag 1 is not heat-sealed and is used as the bag opening E.

[0012] As shown in Figure 1, the plastic film bag 1 of this embodiment comprises an upper portion 11 to which tape 18 (see Figure 3), such as gummed tape, is attached to close the bag opening E, a label attachment portion 12 to which a label is attached, and a main body portion 13. The upper portion 11 and the label attachment portion 12 can be separated from the main body portion 13 by perforations 15, 16, and 17.

[0013] Marks 11a (letters, solid lines, arrows, broken lines, etc.) indicating the position where tape 18 is to be attached are printed or drawn on the top 11 of the plastic film bag 1. These marks 11a are drawn on both the front A and back B of the plastic film. When closing the bag opening E, the top 11 is folded back in a mountain fold, and tape 18 is attached to the folded part (see Figure 3).

[0014] A label attachment section 12 is provided below the upper section 11, where labels printed with addresses, barcodes, etc. are attached. The label attachment section 12 is continuous with the upper section 11, and no cut line is provided between the upper section 11 and the label attachment section 12. Marks 12a (characters, figures, etc.) indicating the label attachment position are printed or drawn on the label attachment section 12.

[0015] The tear line 15 on the front A of the plastic film bag 1 crosses the front A and has a recess 15a. The recess 15a of the tear line 15 partially surrounds the label attachment portion 12. In this embodiment, the recess 15a surrounds three sides of the approximately rectangular label attachment portion 12. The tear line 15 defines the boundary between the upper portion 11 and the label attachment portion 12 and the main body portion 13.

[0016] As shown in Figure 2, the tear line 16 on the back B of the plastic film bag 1 crosses the back B and has a recess 16a. The recess 16a of the tear line 16 partially surrounds the portion 14 corresponding to the label attachment portion 12 on the front A. In this embodiment, it surrounds three sides of the approximately rectangular portion 14. The tear line 16 defines the boundary between the upper portion 11 and the corresponding portion 14 and the main body portion 13.

[0017] A straight cut line 17 continuous with the cut lines 15, 16 on the front A and back B is provided on the gusset C of the plastic film bag 1.

[0018] The tear lines 15, 16, and 17 form a ring around the periphery of the plastic film bag 1. The tear lines 15, 16, and 17 are formed by pressing a perforation cutter against the plastic film bag 1, for example.

[0019] As shown in Figure 3, when using the plastic film bag 1, clothes, small items, and other items are placed into the bag opening E, the top 11 is folded back, and tape 18 is attached to the top 11. This closes the bag opening E. Then, a label (not shown) is attached to the label attachment section 12.

[0020] As shown in Figure 4, when opening plastic film bag 1, label attachment portion 12 on front A of plastic film bag 1 and corresponding portion 14 on back B are firmly grasped and pulled by hand. This separates top portion 11, label attachment portion 12, and corresponding portion 14 from main body portion 13 along perforations 15, 16, and 17. These separated portions 11, 12, and 14 are not recyclable because tape 18 and labels are attached to them. However, main body portion 13, which accounts for more than 60% of the total, can be recycled.

[0021] As shown in FIG. 1 again, a pattern 19 that prevents the barcode of an item placed in the plastic film bag 1 from being read is printed or otherwise drawn on the main body 13 and top 11 of the front A of the plastic film bag 1.

[0022] As described above, a barcode is attached to the label. A barcode is also attached to the item inside the plastic film bag 1. Therefore, even if an attempt is made to read the barcode on the label with a reading device, there is a risk that the barcode of the item inside the plastic film bag 1 may be read instead. To prevent this, pattern 19 is provided. Pattern 19 reflects the red color emitted by the LED or laser diode of the reading device, preventing the barcode of the item inside the plastic film bag 1 from being read.

[0023] The color of the pattern 19 is preferably white, as it reflects the red color emitted by the reading device well, preventing the barcodes of the items inside the plastic film bag 1 from being read. If the pattern 19 is red, it will transmit the red color emitted by the reading device, allowing the barcodes of the items inside the plastic film bag 1 to be read. If the pattern 19 is black, the recycled plastic film bag 1 will appear dark, making it difficult to see what is inside.

[0024] The shape of the pattern 19 is not particularly limited, and may be, for example, a shape in which small and large squares are alternately arranged vertically and horizontally. The shape of the pattern may also be a polka dot pattern or the like.

[0025] The material of the plastic film bag 1 is not particularly limited, and may be, for example, polyethylene, polypropylene, polystyrene, recycled resin raw materials, etc. Recycled resin raw materials are made by collecting waste plastic such as waste plastic film bags, crushing and cleaning them, and turning them into recycled resin pellets using an extruder. In order to achieve the SDGs, it is desirable to use recycled resin raw materials.

[0026] The color of the plastic film bag 1 is not particularly limited, but it is preferably translucent or transparent so that the contents inside can be seen.

[0027] The manufacturing method of the plastic film bag 1 is not particularly limited, and for example, the plastic film bag 1 can be manufactured by forming gussets C on the left and right sides of a cylindrical plastic film, sealing the bottom at a predetermined bag length pitch, and then cutting at a predetermined bag length pitch.

[0028] The configuration of the plastic film bag 1 of this embodiment has been described above. The plastic film bag 1 of this embodiment has the following advantages.

[0029] The upper part 11 to which tape 18 for closing the bag opening E is attached and the label attachment part 12 to which a label is attached can be separated from the main body part 13 along cut lines 15, 16, 17, so that the plastic film bag 1 can be recycled even if the label and tape 18 are attached.

[0030] Since recesses 15a, 16a are provided on the attachment lines 15, 16 on the front A and back B of the plastic film bag 1, the label attachment portion 12 on the front A and the portion 14 corresponding to the label attachment portion 12 on the back B can be firmly grasped by hand to open the plastic film bag 1. This makes the opening operation easier.

[0031] A mark 11a indicating the position where the tape 18 is to be stuck is drawn on the upper part 11 of the plastic film bag 1, so that the tape 18 can be stuck so as not to overlap the cut line 15 on the front A. [Industrial Applicability]

[0032] The plastic film bag 1 of this embodiment is suitable for use in mailing and home delivery of items such as clothing and small items, although there are no particular limitations on its applications. Because a barcode can be printed on the label, it is particularly suitable for delivery bags used by clothing manufacturers when delivering items to mass retailers. Reading the barcode makes it easy to mail or home delivery from the mass retailer's logistics center to each store.

[0033] The present invention is not limited to the above-described embodiment, and can be embodied in other embodiments without departing from the spirit of the present invention.

[0034] In the above embodiment, the plastic film bag has gussets on the left and right sides, but the gussets may be provided on the bottom, or the left and right gussets may be omitted. [Explanation of symbols]
