Description

Durian packaging structure Technical Field

[0001] This application relates to the field of logistics and transportation packaging technology, specifically to a durian packaging structure. Background Technology

[0002] With the rapid development of fresh food e-commerce, people are buying fresh durians more and more frequently on e-commerce platforms.

[0003] Currently, e-commerce companies primarily ship durians that are six to seven tenths ripe. The packaging for durians often uses perforated, breathable cardboard boxes with paper trays. However, as durians ripen, they continuously emit an odor, which can affect other items in the same shipment. Furthermore, durians ripen relatively quickly, making them prone to cracking and spoilage during transport.

[0004] For fresh perishable items like durian, which have a strong odor, there is currently no effective packaging solution or material that can slow down ripening and prevent the spread of odor. Summary of the Invention

[0005] In view of this, this application provides a durian packaging structure, which, through a complete packaging solution consisting of absorbent paper, a breathable packaging bag that can retain the odor to a certain extent, and a shockproof outer box, can effectively prolong the ripening of durian, prevent the odor of durian from dissipating during the transportation of the shipped goods, and extend the delivery time by 24h to 48h.

[0006] To achieve the above objectives, embodiments of this application provide a durian packaging structure, including absorbent paper, a packaging bag, and an outer box. The absorbent paper is used to wrap and cover the outer periphery of the durian. The packaging bag and outer box encapsulate the durian wrapped in absorbent paper. The outer box is used to secure the packaging bag containing the durian inside the outer box.

[0007] Optionally, the absorbent paper has 3 to 5 layers, with multiple layers of absorbent paper stacked on top of the durian's shell and completely encasing it.

[0008] Optionally, the durian packaging structure also includes securing tape, with securing tape pasted and wrapped around the outermost absorbent paper.

[0011] Optionally, the air permeability K of the packaging bag satisfies 20μm / (Pa·s)≤K≤50μm / (Pa·s).

[0012] Optionally, the moisture permeability M of the packaging bag meets 2000g / (m²)2 ·24h)≤M≤4000g / (m 2 •24h).

[0013] Optionally, the burst strength S of the packaging bag must meet the following condition: S≥500KPa.

[0014] Optionally, the packaging bag includes pre-processed edge sealing and closed edge sealing. Pre-processed edge sealing is the edge sealing formed by processing the raw materials of the packaging bag into a bag-shaped structure with a pre-reserved opening. Closed edge sealing is the edge sealing at the opening.

[0015] Optionally, the pre-processed edge banding is ultrasonic edge banding.

[0016] Optionally, the sealing edge is heat-fused.

[0017] Optionally, hot melt adhesive is applied to the sealing edge, and the melting point of the hot melt adhesive is lower than that of the packaging bag.

[0025] Optionally, a slit is provided around the through hole, and the slit extends radially along the through hole; when the durian is placed in the through hole, part of it extends into the buffer space.

[0026] Durians release a large amount of moisture during respiration, leading to increased internal humidity. High humidity accelerates respiration, promotes microbial growth, and thus speeds up ripening. Wrapping the durian with absorbent paper effectively absorbs this moisture, reducing local humidity and slowing down the durian's respiration rate. This reduced respiration rate decreases the durian's energy consumption, thus delaying the ripening process. The durian packaging structure provided in this application, through a complete packaging solution consisting of absorbent paper, a breathable bag that retains some odor, and a shockproof outer box, effectively prolongs durian ripening, prevents the durian's odor from escaping during transport, and extends delivery time by 24 to 48 hours.

[0035] This application provides a durian packaging structure, which, through a complete packaging solution consisting of absorbent paper, a breathable packaging bag that can retain the odor to a certain extent, and a shockproof outer box, can effectively prolong the ripening of durian, prevent the odor of durian from dissipating during the transportation of the shipped goods, and extend the delivery time by 24h to 48h.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] As shown in Figures 1 to 6, the durian packaging structure provided in this application includes absorbent paper 2, packaging bag 3, and outer carton 6.

[0038] Absorbent paper 2 is wrapped around the durian 1 (e.g., a fresh durian) to absorb moisture produced during its respiration and some odor. The packaging bag 3 encloses the fresh durian 1 wrapped with absorbent paper 2, further isolating it from odors. The packaging bag 3 containing the fresh durian 1 is secured inside the outer box 6 for shock absorption.

[0039] During respiration, durian 1 releases a large amount of moisture, leading to increased internal humidity. High humidity promotes microbial growth, and the rapid reproduction of microorganisms damages the durian's outer skin, inducing and exacerbating decay. This stimulates the respiration intensity and ethylene production of fruits and vegetables, thereby accelerating durian ripening (i.e., post-ripening). The absorbent paper 2 wrapped around the durian 1 effectively absorbs this moisture, reducing local humidity, slowing down and preventing microbial growth, and thus slowing the respiration rate of the durian 1. With a reduced respiration rate, the durian 1 consumes less energy, delaying the ripening process. Furthermore, the packaging bag 3, while possessing a certain degree of breathability, maintains a low oxygen concentration within the bag, further reducing the respiration rate of the durian 1, thereby further reducing its ripening effect and preserving its freshness. This application, through its complete packaging solution of absorbent paper 2, a breathable packaging bag 3 that retains some odor, and a shockproof outer box 6, effectively prolongs durian ripening, prevents the odor from escaping during transport, and extends delivery time by 24-48 hours.

[0040] In one embodiment, the absorbent paper 2 has 3 to 5 layers. The multiple layers of absorbent paper 2 are stacked and cover the outer shell of the durian 1, completely enclosing the outer shell of the durian 1. The outermost layer of absorbent paper 2 is covered with fixing tape 7.

[0041] The multi-layered absorbent paper 2 can completely wrap the durian 1's outer shell, preventing any part of the durian 1's shell from being exposed. This allows for better absorption of the moisture produced during the fresh durian 1's respiration and prevents the odor from escaping, keeping the inside of the packaging bag 3 relatively dry. To prevent the absorbent paper 2 from coming apart during transportation, it is best to wrap the outermost layer of absorbent paper 2 with adhesive tape 7.

[0042] In one embodiment, the packaging bag 3 is made of flash-evaporated nonwoven fabric.

[0043] Flash-evaporated nonwoven fabric is waterproof, breathable, lightweight, strong, tear-resistant, and puncture-resistant, making it suitable for fresh durians with hard shells and sharp points. In one example, a flash-evaporated nonwoven fabric made of high-density polyethylene (HDPE) can be used.

[0044] The air permeability and moisture permeability of the packaging need to ensure that the durian 1 can breathe while preventing excessive odor from escaping. The material weight and burst strength also need to prevent the packaging bag 3 from being punctured by the sharp edges of the durian 1's shell. In one embodiment, the material weight W of the packaging bag 3 meets the following requirement: 50 g / m³. 2 ≤W≤60g / m 2 .

[0045] In one embodiment, the air permeability K of the packaging bag 3 satisfies 20μm / (Pa·s)≤K≤50μm / (Pa·s).

[0046] In one embodiment, the moisture permeability M of the packaging bag 3 satisfies 2000 g / (m³). 2 ·24h)≤M≤4000g / (m 2 •24h).

[0047] In one embodiment, the burst strength S of the packaging bag 3 satisfies: S≥500KPa.

[0048] In one embodiment, the packaging bag 3 includes a pre-processed sealing edge 31 before the durian 1 is filled and a sealing edge 32 after the durian 1 is filled. The pre-processed sealing edge 31 is a sealing edge formed by processing the raw material of the packaging bag 3 into a bag-shaped structure with a pre-reserved opening, which can be mass-produced.

[0049] Sealing and edge sealing 32 is the sealing of the opening. After the durian 1 is put into the packaging bag 3 through the opening, the opening is sealed.

[0050] The pre-processed edge banding 31 is ultrasonic edge banding, which is convenient for mass production. Since the sealing edge banding 32 is the edge banding after the durian 1 has been inserted, ultrasonic edge banding is not easy to operate. In one example, the sealing edge banding 32 uses heat fusion edge banding.

[0051] In one embodiment, a sealing hot melt adhesive 33 is provided at the sealing edge 32, and the melting point of the sealing hot melt adhesive 33 is lower than that of the packaging bag 3.

[0052] The sealing edge 32 is a heat-sealing edge, meaning it is sealed using a heat-sealing machine. Since the material of the packaging bag 3 is not heat-resistant, if a conventional heat-sealing machine is used directly, the sealing edge will overheat and melt, causing holes. To ensure the sealing strength during heat sealing, hot melt adhesive 33 is applied to the sealing edge 32. Because the melting point of the hot melt adhesive 33 is lower than that of the packaging bag 3 material, the sealing edge 32 will not overheat, preventing damage to the packaging bag 3.

[0053] To prevent the durian 1 from falling out of the packaging bag 3 due to insufficient strength at the pre-processed edge sealing 31 and the sealing edge sealing 32, in one embodiment, the width of both the pre-processed edge sealing 31 and the sealing edge sealing 32 is greater than or equal to 1 cm.

[0054] In one embodiment, as shown in Figures 3 and 4, the outer box 6 includes a box body 5 and a paper tray 4 disposed inside the box body 5, and the packaging bag 3 containing the durian 1 can be secured between the paper tray 4 and the box body 5.

[0055] In one example, the paper tray 4 includes an upper paper tray 41 and a lower paper tray 42, and the packaging bag 3 containing the fresh durian 1 can be positioned between the upper paper tray 41 and the lower paper tray 42.

[0056] The outer box 6 consists of an upper paper tray 41, a lower paper tray 42, and a box body 5. The upper paper tray 41 and the lower paper tray 42 can limit and buffer the durian 1 inside the packaging bag 3, preventing the durian 1 from being damaged due to violent rolling during transportation.

[0057] In one embodiment, the housing 5 has ventilation holes 51.

[0058] For example, in one example, each side of the housing 5 has at least two ventilation holes 51.

[0059] In order to facilitate ventilation, in addition to the top and bottom surfaces, the box body 5 has two ventilation holes 51 on each of its four sides.

[0060] In one embodiment, as shown in Figures 3-4, both the upper paper tray 41 and the lower paper tray 42 are concave structures. The paper tray 4 includes a paper tray body 43 and an abutment portion 44 disposed on the outer edge of the paper tray body 43. A buffer space is formed between the abutment portion 44, the paper tray body 43, and the box body 5. A through hole 45 is provided in the middle of the paper tray body 43, and slits 46 are provided around the through hole 45, extending radially along the through hole 45. When the durian 1 is placed in the through hole 45, it can partially extend into the buffer space. Due to the tension of the paper tray 4 itself, the size of the slits 46 can be adjusted according to the size and weight of the durian 1. In this way, the size of the through hole 45 can change with the size of the durian 1 itself, always keeping the durian 1 locked inside.

[0061] The packaging process for the fresh durian in this application is as follows:

[0062] 1. Select fresh durians that are about 70% ripe for shipment.

[0063] 2. Select absorbent paper 2 of appropriate size and wrap the fresh durian 1. Wrap 3 to 5 layers of absorbent paper 2 to completely wrap the outer shell of the durian 1, and secure it with adhesive tape 7.

[0064] 3. Use an ultrasonic welding machine to process the raw material of the packaging bag 3 to create a pre-processed sealing edge 31, so that the packaging bag 3 is formed and an opening is reserved for filling the fresh durian 1.

[0065] 4. Place the fresh durian 1 into the packaging bag 3 through the opening, apply hot melt adhesive 33 to the opening, and use a heat sealing machine to heat seal the opening of the packaging bag 3 with the sealing edge 32.

[0066] 5. Place the packaging bag 3 containing the fresh durian 1 between the upper paper tray 41 and the lower paper tray 42 inside the box 5.

[0067] 6. Seal the box.
