Description

Technical Field

[0001] This utility model relates to the field of logistics packaging technology, specifically to a packaging box and a packaging carton. Background Technology

[0002] During transportation, to prevent fragile items (such as delicate and juicy fruits) from physical damage or deterioration in quality during transit, protective packaging is necessary. Mulberries, for example, are relatively delicate, sweet, and juicy, making them prone to damage during transport.

[0003] In related technologies, these fruits are usually pre-cooled at the source of production and transported under a cold chain throughout the entire process, but the damage rate during actual transportation remains high. Utility Model Content

[0004] In view of this, the present invention provides a packaging box and a packaging carton to solve the problem of high damage rate of fragile goods such as fruits during transportation in related technologies.

[0005] In a first aspect, this utility model provides a packaging box, comprising:

[0006] Paper-plastic box, with a storage slot for holding items;

[0007] A lid is placed over the opening of the storage compartment. The lid includes a modified atmosphere film, which is positioned corresponding to the storage compartment and connects the storage compartment of the paper-plastic box to the external space.

[0008] Beneficial effects: The packaging box of this utility model embodiment includes a paper-plastic box and a lid with a modified atmosphere film. The paper-plastic box itself has water absorption properties, which can reduce the damage to fruits with high water content, such as mulberries, caused by high humidity during transportation due to sealed packaging. The modified atmosphere film can reduce the respiration rate of the fruit and slow down metabolism by adjusting the ratio of oxygen and carbon dioxide inside the film, thereby delaying fruit aging and spoilage.

[0009] Therefore, the packaging box of this utility model embodiment can reduce the damage to fragile goods such as fruits caused by high humidity, and delay the aging and spoilage of fruits, thereby reducing the damage rate during actual transportation. When used to transport mulberries, it can effectively reduce the damage caused during the express delivery of mulberries.

[0010] In one optional embodiment, a first adhesive film is provided at the opening of the storage compartment, and the cover includes:

[0011] The second adhesive film is used to adhere to the first adhesive film. The second adhesive film has a clearance opening, which is located at the corresponding position of the storage slot. The modified atmosphere film is placed inside the clearance opening.

[0012] Beneficial effect: With this configuration, the cover can be attached to the opening of the storage compartment via the second adhesive film, thereby sealing the storage compartment.

[0013] In one alternative embodiment, the first adhesive film and / or the second adhesive film are provided with an ethylene absorbent.

[0014] Beneficial effects: Taking mulberries as an example, mulberries are a fruit with a high respiratory climacteric. Ethylene absorbents can effectively control the ripening of mulberries during transportation, thereby delaying fruit aging and spoilage, and reducing the damage rate during actual transportation.

[0015] In one alternative implementation, the storage compartment includes a plurality of limiting slots.

[0016] Beneficial effects: The limiting groove can limit the movement of fruits, thereby preventing them from squeezing each other during transportation and reducing damage to the fruits during transportation.

[0017] In one optional embodiment, the pulp of the paper-plastic box includes sugarcane pulp, bamboo pulp and wood pulp, and the ratio of sugarcane pulp, bamboo pulp and wood pulp is: 10%~20%: 20%~30%: 55%~65%.

[0018] Beneficial effects: When the pulp ratio of paper-plastic boxes is within the above range, it can effectively reduce the damage to goods caused by high humidity during transportation due to sealed packaging, and reduce the damage rate during actual transportation.

[0019] In one optional embodiment, the thickness of the controlled atmosphere film is w1, 50 μm ≤ w1 ≤ 90 μm; and / or,

[0020] The air permeability of the modified atmosphere membrane is k, where 300 mm / s ≤ k ≤ 400 mm / s.

[0021] Beneficial effects: When the thickness of the modified atmosphere film is within the above range, it can ensure that the modified atmosphere film can reliably protect the fruit, and the air permeability of the modified atmosphere film is moderate.

[0022] Mulberries are a fruit with a high respiratory climacteric rate. When the permeability of the modified atmosphere membrane is within the above-mentioned range, it can help reduce the physiological loss of mulberries during transportation and reduce the damage rate during actual transportation.

[0023] Secondly, this utility model also provides a packaging box, comprising:

[0024] The packaging box of the first aspect of this utility model;

[0025] The box and packaging are located inside the box, which contains a refrigerant tank for holding the refrigerant.

[0026] Beneficial effects: By setting it up in this way, the packaging box can reduce the damage to fragile products such as fruits caused by high humidity, and delay the aging and spoilage of the fruit. The box can hold refrigerant, which can then inhibit the respiration intensity of the fruit through low temperature, reduce energy consumption, inhibit the growth of microorganisms, and reduce water evaporation.

[0027] Therefore, the packaging box of the second aspect of this utility model combines two preservation technologies, modified atmosphere and temperature control, which can reduce the damage rate during actual transportation. When used to transport mulberries, it can effectively reduce the damage caused during the express delivery of mulberries.

[0028] In one optional embodiment, the box is provided with a partition, and receiving slots are formed on both sides of the partition. The packaging box is placed in the receiving slot, and the refrigerant tank is placed on the partition.

[0029] Beneficial effects: With this design, the divider can not only be used to create a receiving slot inside the box to limit the packaging box and prevent it from being damaged by vibration during transportation, but also to hold the refrigerant and prevent the condensate produced by the refrigerant during use from coming into contact with the packaging box and causing damage.

[0030] In one alternative implementation, the box is a foam box.

[0031] Beneficial effects: Foam boxes can work with refrigerants to maintain the temperature inside the box, have good cushioning properties, and can create a semi-enclosed environment, allowing carbon dioxide to accumulate naturally, inhibiting mold activity, and slowing down the respiration of fruits.

[0032] In one optional embodiment, the thickness of the housing is w2, 15mm ≤ w2 ≤ 30mm; and / or,

[0033] The density of the box is ρ, ρ≥18Kg / m³ 3 .

[0034] Beneficial effects: When the density of the foam box is within the above range, the dense structure can improve the resistance to compression, load-bearing capacity and deformation resistance, extend the service life and support reuse, while enhancing moisture resistance and shape stability, making it suitable for heavy cargo transportation, customized packaging, multiple turnovers or fruit protection needs in extreme environments.
