[0001] This utility model relates to the field of express delivery bag technology, and in particular to a waterproof and shock-resistant express delivery bag that is easy to reuse. [Background Technology]

[0002] Currently, most common express delivery bags are made of plastic. However, plastic bags are easily worn and damaged during actual transportation, potentially leading to lost or damaged items. Furthermore, consumers often violently tear open packages, making the bags inconvenient to reuse and wasting resources. Plastic bags are also not environmentally friendly, are non-biodegradable, and easily pollute the environment. While some express delivery bags, such as envelopes, are used, these are also not easily reusable. Given these problems, there is an urgent need for an express delivery bag that is convenient to reuse and has waterproof and shock-resistant properties. [Utility Model Content]

[0003] The technical problem to be solved by this utility model is to provide a waterproof and shock-resistant express bag that is easy to reuse after being opened, and has waterproof and shock-resistant properties.

[0035] Please see Figures 1 to 5 As shown, this utility model discloses a waterproof and shock-resistant express bag 100 that is easy to reuse. The express bag 100 includes a paper bag body 1 with a bag opening 11 and a flap 2 for closing the bag opening 11. Folding handles 3 are provided on both sides inside the paper bag body 1, which can be folded out to the outside of the bag opening 11. When the express bag 100 is used for the first time, the folding handles 3 need to be folded inside the paper bag body 1 to ensure that the flap 2 can close the bag opening 11. When the express bag 100 is used as a tote bag for the second time, the folding handles 3 can be folded out to the outside of the bag opening 11 so that the entire express bag 100 can be carried with the help of the folding handles 3.

[0036] Please refer to the following carefully. Figure 5As shown, the cross-section of the paper bag body 1 includes, from the inside out, a first functional layer 12, a paper substrate layer 13, and a second functional layer 14. The second functional layer 14 is a waterproof layer, which enables the paper bag body 1 to have waterproof performance. In this way, when the express bag 100 comes into contact with water during use, it will not be easily damaged like other conventional paper, and the degree of damage to the express bag 100 can be minimized, thereby ensuring the packaging performance of the express bag 100.

[0037] To ensure the strength of the express bag 100, the paper substrate layer 13 is designed as follows:

[0038] As the first specific embodiment of this utility model, the paper substrate layer 13 is made of stretchable paper. Stretchable paper has advantages such as strong and tough paper, not easy to break, and good waterproof performance, which can effectively prevent the express bag 100 from being damaged during loading and unloading.

[0039] As a second specific embodiment of this utility model, the paper substrate layer 13 is made of wet-strength paper, which refers to paper with added wet-strength agent. The dry strength of wet-strength paper is greater than 20%, and when it is damp or soaked in water, it still maintains more than 15% dry strength and can resist cracking or disintegration.

[0040] As a third specific embodiment of this utility model, the paper substrate layer 13 is made of long-fiber virgin pulp paper. Long-fiber virgin pulp paper refers to paper made from long-fiber virgin pulp, which has advantages such as high toughness, resistance to breakage, high softness, and good water absorption. Of course, the above are only three specific embodiments listed in this utility model, but this utility model is not limited to these. In specific implementations, other papers with higher strength can also be used as the paper substrate layer 13 according to actual needs.

[0041] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0042] 1. The paper bag body 1 is designed to include, from the inside out, a first functional layer 12, a paper substrate layer 13, and a second functional layer 14. The paper substrate layer 13 is made of high-strength paper, and the second functional layer 14 is a waterproof layer. Through the cooperation of the paper substrate layer 13 and the second functional layer 14, the waterproof and shock-resistant performance of the express bag 100 can be effectively improved, making the express bag 100 less susceptible to wear and damage during transportation or in rainy weather. This allows the express bag 100 to better maintain its integrity, ensuring that the contents are less likely to be lost or damaged, and also provides conditions for the reuse of the express bag 100.

[0043] 2. A folding handle 3 is provided on the inside of the paper bag body 1, which can be folded out to the outside of the bag opening 11. This allows the consumer to fold the handle 3 out to the outside of the bag opening 11 after opening the bag opening 11 to take out the package, thus forming a tote bag. Figure 3 As shown, this allows for the reuse of the express bag 100, thus avoiding resource waste.

[0044] 3. Compared with plastic express delivery bags, paper express delivery bags are more environmentally friendly and biodegradable, and will not pollute the environment, which is beneficial to environmental protection.

[0045] Regarding the second functional layer 14:

[0046] In the first specific embodiment of this utility model, the second functional layer 14 is a waterproof coating, that is, a waterproof agent is applied to the outer surface of the paper bag body 1 to achieve a certain waterproof effect.

[0047] As a second specific embodiment of the present invention, the second functional layer 14 is a coating layer, that is, a thin film is covered on the outer surface of the paper bag body 1 by a coating process, and the film can be a plastic film or a biodegradable biofilm to achieve a certain waterproof effect.

[0048] For the first functional layer 12:

[0049] In the first specific embodiment of this utility model, the first functional layer 12 is an oil-resistant coating to achieve an oil-resistant effect. In this way, when oil drips onto the inner surface of the express bag 100 during actual use, the oil can be wiped off quickly, which helps to extend the service life of the express bag 100.

[0050] In the first specific embodiment of this utility model, the first functional layer 12 is an antibacterial coating to achieve an antibacterial effect and ensure that items placed in the express bag 100 are not prone to mold or other problems.

[0051] In this invention, the flap 2 is integrally connected to the paper bag body 1. Specifically, the flap 2 is formed by extending the upper part of the bag surface on one side of the paper bag body 1 directly upwards, which makes production more convenient. Of course, this invention is not limited to this. In specific implementations, the flap 2 and the paper bag body 1 can also be formed separately and then the flap 2 can be glued together with the paper bag body 1. However, this method is more complicated to manufacture and is not conducive to improving production efficiency.

[0052] In this invention, an adhesive part 4 is provided on the inner side of the flap 2 or on the outer side of the paper bag body 1 near the bag opening 11, and the adhesive part 4 is equipped with a protective layer 41. In a specific implementation of this invention, the adhesive part 4 is an adhesive applied to the inner side of the flap 2 or the outer side of the paper bag body 1. The adhesive can be hot melt adhesive, water-based adhesive, oil-based adhesive, etc. The protective layer 41 can be release paper, plastic film, etc., and before the bag opening 11 is sealed, the protective layer 41 can protect the adhesive part 4. Figure 1As shown; when sealing the bag opening 11, the protective layer 41 needs to be torn off so that the adhesive part 4 can stick the flap 2 to the paper bag body 1 together to achieve sealing, as shown. Figure 2 As shown.

[0053] In this utility model, a tear strip or tear line 5 is provided between the tongue opening 2 or the tongue opening 2 and the paper bag body 1. For example... Figure 3 As shown, by setting a tear strip or tear line 5 between the flap 2 and the paper bag body 1 or on the flap 2, the user can neatly tear open the bag opening 11 with the tear strip or tear line 5 during actual use without damaging the bag body, thus making it convenient to reuse the express bag 100 after taking out the items.

[0054] In this invention, the lower end of the folding handle 3 is adhered to the inner side of the paper bag body 1 by an adhesive strip 31. In a specific implementation of this invention, the adhesive strip 31 is coated with adhesive on the side facing the folding handle 3, and the adhesive is used to adhere and fix the lower end of the folding handle 3 to the inner side of the paper bag body 1. The adhesive can be hot melt adhesive, water-based adhesive, oil-based adhesive, etc., while the side of the adhesive strip 31 facing away from the folding handle 3 is not coated with adhesive.

[0055] In this invention, the folding handles 3 on both sides are staggered, which makes it easier to stack and store the express bag 100 when not in use and avoids protrusions at the folding handles 3.

[0056] In this utility model, the outer surface of the paper bag body 1 is provided with a waybill pasting area 15 so that the waybill can be pasted on the express bag 100 at a designated position during use.
