Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective bag technology, and in particular to a protective bag for young fruit. Background Technology
[0002] Currently, the market offers a wide variety of protective bags for young fruit, including double-layered bags with an inner waxed paper layer and an outer paper layer, and single-layered plastic film bags. However, both of these typical protective bags have their limitations. Specifically, while double-layered bags with an inner waxed paper layer and an outer paper layer are favored by fruit growers, the interior is prone to moisture buildup due to the fruit's respiration, leading to a damp environment that breeds bacteria and negatively impacts fruit growth. Single-layered plastic film bags are not effective at blocking direct sunlight, and as the young fruit matures and changes color, they are not effective at preventing birds from pecking at it. In addition, existing protective bags have poor expansion properties, and as the fruit grows, the internal space of the bag can become restrictive. Therefore, there is an urgent need to develop a protective bag for young fruit that uses a pleated design to allow the bag to expand further, providing more space for the fruit as it grows; a bag that effectively prevents sun exposure, pests, diseases, and bird pecking, offering higher protection to overcome the shortcomings of current applications and meet current needs. Utility Model Content
[0003] The purpose of this utility model is to provide a protective bag for young fruit to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A protective bag for young fruit includes a protective sleeve with pleats, a heat-sealing area at the upper inner end of the protective sleeve, and two positioning soft iron wires fixed at the opening of the protective sleeve. The protective sleeve includes an outer layer, an inner layer, and a graphene coating, with the inner layer fixed to the inside of the outer layer and the graphene coating fixed to the inside of the inner layer.
[0006] Preferably, the outer layer is made of wood pulp paper, straw pulp paper, or kraft paper.
[0007] Preferably, the inner layer is made of polyethylene plastic film.
[0008] Preferably, the diameter of the positioning soft iron wire is 1mm.
[0009] The beneficial effects of this utility model are as follows: When using this fruit young fruit protective bag, the protective bag is placed in the bagging machine, and then the fruit is inserted into the protective bag. The bagging machine then squeezes and merges the bag opening, and heats it to fuse and fix the heat-sealed area at the bag opening together. The pleats allow the protective bag to expand further. As the large fruit grows inside the protective bag, it expands accordingly to provide growth space. The outer and inner layers provide double protection for the fruit, preventing damage from pests and diseases and strong sunlight, and effectively preventing birds and other animals from pecking at it. In addition, the graphene coating has good gas barrier properties, which can prevent oxygen and water vapor from entering the bag, slow down the fruit's respiration and water loss, inhibit the growth of microorganisms, and prevent fogging on the inner surface of the bag, making it difficult for water vapor to form small water droplets on the inner surface of the bag, thereby keeping the fruit surface dry and reducing the occurrence of diseases caused by a humid environment. In summary, this utility model, through its pleated design, allows the bag to expand further, providing more space for the fruit to grow; it also effectively prevents sun exposure, pests and diseases, and bird pecking, offering enhanced protection.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0015] Specific implementation examples are given below.
[0016] See Figures 1-2In this embodiment of the invention, a protective bag for young fruit includes a protective bag 1. The protective bag 1 has pleats 101, which allow it to expand further. As the fruit grows inside the protective bag 1, it expands accordingly to provide growth space. A heat-sealing area 102 is located at the upper interior of the protective bag 1. During heat sealing, a bagging machine squeezes the opening of the protective bag 1 together and heats it, causing the heat at the opening of the protective bag 1 to... The sealing area 102 is fused and fixed together. Two positioning soft iron wires 2 are fixed at the opening of the protective bag 1. The diameter of the positioning soft iron wires 2 is 1mm. The positioning soft iron wires 2 can maintain the shape of the opening of the protective bag 1. The protective bag 1 includes: an outer layer 3, an inner layer 4 and a graphene coating 5. The outer layer 3 is made of wood pulp paper, straw pulp paper or kraft paper. The inner layer 4 is made of polyethylene plastic film. The inner layer 4 is fixed to the inside of the outer layer 3. The graphene coating 5 is fixed to the inside of the inner layer 4.
[0017] Working principle: When using this fruit young fruit protective bag, the protective bag 1 is placed in the bagging machine, and then the fruit is inserted into the protective bag 1. The bagging machine then squeezes and closes the opening of the protective bag 1, and heats it to fuse and fix the heat-sealed area 102 at the opening of the protective bag 1 together. The pleats 101 allow the protective bag 1 to expand further. As the large fruit grows inside the protective bag 1, the protective bag 1 can expand accordingly to provide growth space. The outer layer 3 and inner layer 4 provide double protection for the fruit, preventing damage from pests and diseases and strong sunlight, and effectively preventing pecking behavior by birds and other animals. In addition, the graphene coating 5 has good gas barrier properties, which can prevent oxygen and water vapor from entering the bag, slow down the respiration and water loss of the fruit, inhibit the growth of microorganisms, and prevent fogging on the inner surface of the bag, making it difficult for water vapor to form small water droplets on the inner surface of the bag, thereby keeping the fruit surface dry and reducing the occurrence of diseases caused by humid environments.
[0018] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
