[0026] The present application provides a durian packaging structure, which uses a complete packaging solution consisting of absorbent paper, a breathable packaging bag that can trap odors to a certain extent, and a shockproof outer box. This can effectively prolong the ripening of durian, prevent the release of durian odor during the transportation of consignments, and extend the shipping time by 24h-48h.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] like Figures 1-4 As shown, the durian packaging structure provided by this application includes:

[0029] The absorbent paper 2 is wrapped around the periphery of the fresh durian 1 to absorb the moisture generated during the respiration of the fresh durian 1 and absorb certain odors;

[0030] The packaging bag 3 can enclose the fresh durian 1 wrapped with the absorbent paper 2, thereby further isolating the odor;

[0031] The outer box, in which the packaging bag 3 containing the fresh durian 1 is fixed, plays a shockproof role.

[0032] This application uses a complete packaging solution consisting of absorbent paper 2, a breathable packaging bag 3 that can trap odors to a certain extent, and a shockproof outer box, which can effectively prolong the ripening of durian, prevent the release of durian odor during the transportation of consignments, and extend the shipping time by 24h-48h.

[0033] In a preferred embodiment, the number of layers of absorbent paper 2 is 3-5 layers, and the multiple layers of absorbent paper 2 are stacked and covered on the durian shell to completely wrap the durian shell inside, and a fixing tape is pasted and wrapped on the outermost layer of absorbent paper 2.

[0034] The multi-layer absorbent paper 2 can wrap the durian shell more completely, preventing part of the durian shell from being exposed. This can better absorb the moisture generated during the breathing process of the fresh durian 1 and prevent the odor from escaping, so that the packaging bag 3 remains relatively dry. In order to prevent the absorbent paper 2 from spreading during transportation, it is best to wrap the outermost layer of absorbent paper 2 with fixing tape.

[0035] In a preferred embodiment, the packaging bag 3 is made of flash-steamed non-woven fabric.

[0036] The flash-steamed non-woven fabric material is waterproof, breathable, lightweight, strong, tear-resistant and puncture-resistant, and is suitable for fresh durian 1 with a hard shell and sharp thorns; preferably, a flash-steamed non-woven fabric material of HDPE can be used.

[0037] The air permeability and moisture permeability of the packaging need to ensure the breathing of the durian itself and prevent excessive odor from escaping. The material weight and burst resistance also need to prevent the packaging bag 3 from being broken by the thorns of the durian shell. In a preferred embodiment, the material weight W of the packaging bag 3 meets the following requirements: 50g / m 2 ≤W≤60g / m 2 and / or, the air permeability K of the packaging bag 3 satisfies 20 μm / (Pa·s)≤K≤50 μm / (Pa.s), and / or, the moisture permeability M of the packaging bag 3 satisfies 2000 g / (m 2 ·24h)≤M≤4000g / (m 2 ·24h), and / or, the bursting strength S of the packaging bag 3 satisfies: S≥500KPa.

[0038] In a preferred embodiment, the packaging bag 3 includes a pre-processed edge seal before the durian is loaded and a sealed edge seal after the durian is loaded, that is, the pre-processed edge seal is formed by processing the raw material of the packaging bag 3 into a bag-shaped structure with an opening reserved, which can be mass-produced;

[0039] The sealing edge is the edge sealing at the opening. After the durian is put into the packaging bag 3 from the opening, the opening is sealed;

[0040] The pre-processed edge sealing is ultrasonic edge sealing, which is convenient for mass production. Since the sealing edge sealing is performed after the durian has been loaded, ultrasonic edge sealing is not easy to operate, and hot melt edge sealing is preferably used for the sealing edge sealing.

[0041] In a preferred embodiment, edge sealing hot melt glue is provided at the sealing edge, and the melting point of the edge sealing hot melt glue is lower than the melting point of the packaging bag 3.

[0042] The sealing edge is hot-melt sealing, that is, the edge is sealed with a heat sealer. Since the material of the packaging bag 3 is not heat-resistant, if a conventional heat sealer is used to directly heat seal it, the edge will overheat and melt, and holes will form. In order to ensure the sealing strength during heat sealing, hot-melt glue is applied to the sealing edge. Since the melting point of the hot-melt glue is lower than the melting point of the material of the packaging bag 3, the sealing edge can be prevented from overheating and the packaging bag 3 will not be damaged.

[0043] In order to prevent the durian from falling out of the packaging bag 3 from the pre-processing edge seal and the sealing edge seal due to insufficient strength of the pre-processing edge seal and the sealing edge seal, in a preferred embodiment, the width of the pre-processing edge seal and the sealing edge seal is greater than or equal to 1 cm.

[0044] In a preferred embodiment, Figure 3-Figure 4 As shown, the outer box includes a box body 5 and a paper support 4 arranged in the box body 5. The paper support 4 includes an upper paper support 41 and a lower paper support 42. The packaging bag 3 containing the fresh durian 1 can be stuck between the upper paper support 41 and the lower paper support 42.

[0045] The outer box is composed of an upper paper support 41, a lower paper support 42 and a box body 5. The upper paper support 41 and the lower paper support 42 can limit and buffer the durian in the packaging bag 3 to prevent the durian from being damaged by violent rolling during transportation.

[0046] In a preferred embodiment, each side of the box body 5 is provided with at least two ventilation holes.

[0047] In order to achieve the purpose of ventilation, the box body 5 has two holes on each of the four side surfaces except the upper and lower bottom surfaces.

[0048] In a preferred embodiment, Figure 3-Figure 4 As shown, the upper paper support 41 / the lower paper support 42 are both "concave" structures, and the paper support 4 includes a paper support body and an abutment portion arranged on the outer edge of the paper support body, and a buffer space is formed between the abutment portion, the paper support body and the box body 5; a through hole is provided in the middle of the paper support body, and cracks are provided around the through hole, and the cracks extend along the radial direction of the through hole; when the durian is placed in the through hole, it can partially extend into the buffer space, and due to the tension of the paper support 4 itself, the size of the crack will adjust itself according to the size and weight of the durian; the size of the through hole can change with the size of the durian itself, and the durian is always stuck inside.

[0049] The packaging process of the fresh durian in this application is as follows:

[0050] 1. Choose fresh durian that is about 70% mature for shipment;

[0051] 2. Choose a piece of absorbent paper 2 of appropriate size to wrap the fresh durian 1. Wrap the absorbent paper 2 in 3-5 layers, completely wrapping the durian shell and securing it with fixing tape;

[0052] 3. Use an ultrasonic welding machine to process the raw materials of the packaging bag 3 into pre-processed edge seals, so that the packaging bag 3 is formed and an opening is reserved for loading the fresh durian 1;

[0053] 4. Put the fresh durian 1 into the packaging bag 3 through the opening, apply hot melt glue to the edge of the opening, and use a heat sealing machine to heat seal the edge of the opening of the packaging bag 3;

[0054] 5. Place the packaging bag 3 containing the fresh durian 1 between the upper paper support 41 and the lower paper support 42 in the box 5;

[0055] 6. Seal the box.

[0056] The packaging materials involved in the packaging solution of the durian packaging structure of this application have all determined specific technical parameters, and the operation methods and packaging materials have been proofed, and can be industrially produced.
