Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a breathable packaging bag. Background Technology

[0002] In modern logistics and commodity storage, breathable packaging bags play a crucial role. Many products, including food, pharmaceuticals, and some chemical products, have special requirements for their packaging environment during storage and transportation. On the one hand, the packaging needs to provide necessary physical protection to prevent damage from collisions and compression. On the other hand, good breathability is also crucial for maintaining product quality. For example, if food products are not packaged breathably, they are prone to mold and spoilage due to moisture accumulation. If pharmaceuticals are placed in a non-breathable packaging environment, their chemical stability may be affected, reducing their efficacy. Therefore, breathable packaging bags can effectively balance the protection and breathability requirements for product preservation, ensuring the quality and safety of products during distribution.

[0003] However, traditional breathable packaging bag technology has many drawbacks. First, in terms of structural design, traditional packaging bags often rely solely on a single material to achieve breathability. This simple structure results in poor protective performance. When faced with complex transportation environments, such as bumps and collisions, the bag is easily damaged, leaving the product unprotected and causing economic losses. Second, traditional breathable packaging bags do not precisely balance breathability and protection. Either the breathability is too strong, allowing excessive dust and impurities to enter the packaging and contaminate the product; or it prioritizes protection at the expense of breathability, failing to meet the product's air circulation needs and affecting product quality. These shortcomings not only reduce the reliability and practicality of the packaging but also negatively impact the market circulation and use of the product. To address these issues, we have proposed a breathable packaging bag. Utility Model Content

[0028] Structural Description:

[0029] Bag body: The bag body is the main structure of the breathable packaging bag, which carries the inner bag and other auxiliary structures, forming the spatial framework of the entire packaging. It has a certain strength and flexibility to adapt to the packaging needs of different items. There are molding blocks on the top two sides and a pressing strip on the front. These structures work together with other components to enable the bag body not only to hold items, but also to play a key role in sealing and shaping. It is the basic framework for the packaging bag to achieve multiple functions.

[0030] Shaping blocks: Located on both sides of the top of the bag, shaping blocks are a structure that helps the bag maintain a specific shape. They have a certain degree of hardness and toughness. During the storage or handling of the packaging bag, they can help maintain the shape of the top of the bag and prevent the top from deforming arbitrarily due to external forces. This prevention of deformation is crucial for maintaining the sealing effect of the packaging bag, ensuring a stable storage environment for the items inside the bag, and also improving the convenience and aesthetics of the packaging bag during use.

[0031] Compression strip: The compression strip is located on the front of the bag and is one of the key structures to achieve the sealing function of the packaging bag. It works closely with the sealing strip on the top of the sealing wing and the inner pressure strip of the side wing. When the sealing wing covers the bag, the compression strip can interact with the sealing strip through pressing and other operations to generate sufficient pressure, thereby achieving the sealing of the bag and effectively preventing the leakage of the contents of the bag and the entry of outside air and moisture into the bag.

[0032] Sealing Wings: Sealing wings are movable structures located at the opening of the bag. Their main function is to seal the packaging bag. They have a label slot on the front, made of transparent material, which makes it easy for users to insert product labels and other information cards. Sealing strips are provided on both sides of the top of the sealing wings. When packaging items, the sealing wings cover the bag and work together with the pressing strip on the front of the bag and the pressing strip on the inside of the side wings to complete the sealing process, ensuring the airtightness and safety of the items inside the bag.

[0033] Sealing strip: The sealing strip is installed on both sides of the top of the sealing wings and is a key component for achieving the sealing function. Its material has good elasticity and sealing performance. When the sealing wings cooperate with the bag body to perform the sealing operation, the sealing strip fits tightly with the pressing strip on the front of the bag body. It uses its own elastic deformation to fill any gaps that may exist, thereby preventing the entry and exit of air, moisture and impurities, ensuring the stability of the internal environment of the packaging bag, and providing good preservation conditions for the items inside the bag.

[0034] Side wings: The side wings are structures connected to both sides of the bag body, which play a role in assisting sealing and enhancing structural stability. They have pressure strips on their inner sides, which work together with the pressure strip on the front of the bag body and the sealing strip on the top of the sealing wing. When the sealing wing covers the bag body, the pressure strip on the inner side of the side wing helps to press it tight, further strengthening the sealing effect and ensuring good sealing of the packaging bag. At the same time, it also provides additional structural support for the entire packaging bag, making it more stable during handling and storage.

[0035] Inner bag: The inner bag is the structure inside the breathable packaging bag that directly holds the items. It is made of a specific material and has a certain degree of flexibility and durability. It has internal ribs that are evenly distributed inside the inner bag, which, like reinforcing ribs, significantly enhance the structural strength of the inner bag. This allows the inner bag to effectively distribute pressure when items are placed inside or when it is subjected to external pressure, preventing the inner bag from being easily damaged and thus providing reliable direct protection for the items inside.

[0036] Resilient strips: The resilient strips are evenly distributed inside the inner bag and are an important component that enhances the structural strength of the inner bag. They are distributed linearly or in a grid pattern inside the inner bag. During the packaging and handling of goods, when the inner bag is squeezed or impacted, the resilient strips can effectively absorb and disperse external forces with their own characteristics, preventing the inner bag from breaking due to excessive local stress. This ensures that the inner bag continues to protect the goods and greatly improves the safety of the goods during packaging and transportation.

[0037] Outer breathable layer: The outer breathable layer is the outer breathable structure of the breathable packaging bag. It is usually made of a breathable material and has a specific arrangement of pores on its surface. It can ensure that the inside of the packaging bag can have an appropriate gas exchange with the external environment, prevent damage to the goods due to moisture accumulation, and also block dust, impurities and other pollutants from entering the bag to a certain extent. It plays a preliminary role in protecting the goods inside the bag and regulating the breathability. It is an important part of maintaining a suitable environment inside the packaging bag.

[0038] Activated carbon filling layer: The activated carbon filling layer is a functional structure between the outer and inner breathable layers. It is composed of activated carbon material with a rich pore structure. It utilizes the strong adsorption properties of activated carbon to adsorb odors, harmful gases and excess moisture that may be generated inside the packaging bag, further purifying the environment inside the bag and creating a fresher and drier storage space for the items inside, thereby extending the shelf life of the items and improving the quality of the packaging and the protective effect on the items.

[0039] Inner breathable layer: The inner breathable layer is a breathable structure close to the inner bag. Its material also has good breathability. It works together with the outer breathable layer to ensure that gas can flow smoothly inside and outside the packaging bag, while providing a certain degree of protection for the inner bag. It prevents particles and other substances in the activated carbon filling layer from contacting and damaging the inner bag and the items inside. At the same time, it helps maintain the stability of the environment around the inner bag. It is an indispensable part of the packaging bag's breathable system.

[0040] Label slot: The label slot is a structure set on the front of the sealing wing. It is generally made of transparent material. Its shape and size are specially designed for inserting product labels, so that users can clearly see relevant product information, such as product name, specifications, and production date, without opening the packaging bag. It provides convenience for product identification, management and sales, and is a part of the packaging bag with practical information display function.

[0041] Working principle: First, the bag body 1, as the main structure of the entire packaging bag, provides space for the contents. The sealing wings 2 at the top play a crucial sealing role during the packaging process. When the bag body 1 needs to be sealed, the sealing wings 2, through the cooperation of the sealing strips 201 on both sides of the top, the pressing strip 102 on the front of the bag body 1, and the pressing strips on the inner side of the side wings 3, achieve a tight seal. The pressing strips on the inner side of the sealing wings 2, which are adapted to the pressing strip 102, and the pressing strips on the inner side of the side wings 3, which are adapted to the sealing strip 201, when a certain amount of pressure is applied... After pressure is applied, the pressure strip adheres to the sealing strip 201, effectively preventing outside air and moisture from entering the bag and ensuring a relatively stable environment for the contents. Simultaneously, the outer breathable layer 5, activated carbon filling layer 6, and inner breathable layer 7 on both sides of the bag body 1 work together to provide ventilation. The hexagonal perforations evenly spaced on the outer breathable layer 5 allow initial entry of outside air into the bag. This air then passes through the activated carbon filling layer 6, which is adhered to the outer breathable layer 5. Activated carbon has a strong adsorption capacity. It can absorb odors, moisture, and some impurities in the air, thereby purifying the incoming air. The purified air continues to flow inward, entering the bag body 1 through the equidistant circular through-holes on the outer side of the inner breathable layer 7. It is worth noting that the staggered design of the through-holes of the inner breathable layer 7 and the outer breathable layer 5 further optimizes the breathability, preventing external impurities from directly entering the bag through the through-holes while ensuring air circulation. The tough strips 401 inside the inner bag 4 enhance the structural strength of the inner bag 4, preventing it from being easily damaged when items are placed inside or when subjected to external pressure, thus providing better protection for the contents. In addition, the molding blocks 101 on both sides of the top of the bag body 1 help to shape the top of the packaging bag, keeping it in a certain shape during storage or transportation, and preventing the top from deforming arbitrarily due to external forces, which would affect the sealing effect. The label slot 8 on the front of the sealing wing 2 is made of transparent material, making it convenient for users to insert product labels and other information cards, facilitating the identification and classification of the contents of the bag, and allowing for quick access to relevant information without opening the packaging bag.
