Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bag technology, and in particular to a PPE industrial packaging plastic bag. Background Technology
[0002] In the fields of industrial production and logistics transportation, the performance of packaging materials directly affects the storage safety and transportation efficiency of goods. As a commonly used packaging container, industrial packaging plastic bags must meet core requirements such as high structural strength, good sealing performance, and ease of operation to adapt to the diverse storage and transportation needs of industrial products.
[0003] However, existing technologies, such as Chinese Publication No. CN219566051U, describe a PPE industrial packaging plastic bag, which includes a sealing layer, an anti-tensile layer bonded to the outer side of the sealing layer, an adhesive seam on the inner side of the sealing layer, a sealing strip bonded to the inner side of the sealing layer, and a binding rope bonded to the outer side of the sealing strip, extending to the outer side of the sealing layer. The cooperation of the anti-tensile layer and the inner reinforcement layer improves the structural strength of the PPE industrial packaging plastic bag. At the same time, the anti-tensile layer reduces external wear on the sealing layer, and the inner reinforcement layer reduces wear between the industrial products in the filling area and the inner side of the sealing layer, preventing excessive wear of the sealing layer from causing holes and leakage of goods from the device. The design of the sealing strip and the adhesive seam allows users to easily remove the PPE industrial packaging plastic bag by pulling the sealing strip with the binding rope to release the connection of the outer adhesive seam of the sealing layer, achieving rapid removal of the packaging and solving the problem of easy breakage and leakage of goods caused by existing industrial packaging plastic bags.
[0004] However, during use, it was found that the device's structural strength is not high. Its sealing layer only uses heat-pressed stitching at the bottom, which may become a weak point when bearing heavy loads. As the weight of the goods increases, cracks easily appear at the bottom heat-pressed stitching, affecting the overall sealing and load-bearing capacity. Furthermore, the hook and loop sides of the Velcro will lose their adhesiveness after long-term use or after accumulating dust and oil, resulting in an insecure seal and the possibility of goods falling out or external impurities entering. Moreover, in industrial environments, industrial debris easily adheres to the Velcro surface, further affecting its adhesion. Additionally, the plastic bags provided by this device lack identification functionality, making it difficult to quickly identify the type, quantity, and weight of the industrial products loaded inside during industrial storage and transportation, which is detrimental to management and inventory. Summary of the Invention
[0005] The purpose of this invention is to solve the problems of insufficient structural strength, inconvenient sealing and operation, and limited functionality in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a PPE industrial packaging plastic bag, comprising: a bag body; a pair of handles fixedly connected to the upper middle part of both sides of the bag body; multiple sets of layered components installed inside the bag body; a load-bearing reinforcement component installed inside the bag body; and zippers installed on both sides of the opening at the upper end of the bag body.
[0007] The technical advantages of adopting the above-mentioned further solution are: the handles on both sides facilitate handling; the multi-component layered assembly divides the interior into multiple independent compartments, enabling the categorized storage of different items; the internal load-bearing reinforcement components enhance load-bearing capacity; and the top zipper seals the opening, thus improving the overall convenience of categorization, load-bearing safety, and sealing reliability of industrial product packaging.
[0008] In a preferred embodiment, the layering component includes: a folding layering cavity, one side of which is fixedly connected to the inner side of the bag body; and snap fasteners, respectively disposed on one side of the folding layering cavity and the inner side of the bag body.
[0009] The technical advantage of adopting the above-mentioned further solution is that spatial separation is achieved through a folded, layered cavity fixed to one side of the bag. Combined with snap fasteners located on one side of the folded, layered cavity and the inside of the bag, the layered structure can be flexibly fixed. This design ensures the independence of categorized storage while allowing adjustment of the layered state via snap fasteners, thus improving the flexibility and stability of categorizing and storing items within the packaging.
[0010] In a preferred embodiment, the load-bearing reinforcement component includes: an annular elastic support ring, installed on the inner side of the bottom surface of the bag body, the diameter of which is consistent with the short side of the bottom surface of the bag body, and a memory metal wire is embedded inside it.
[0011] The technical effect of adopting the above-mentioned further solution is as follows: the bottom load-bearing capacity is enhanced by the annular elastic support ring on the inner side of the bag bottom, the diameter of which matches and adapts to the bag body. The memory metal wire embedded in the support ring gives the structure elasticity and shape retention, which can stably bear the weight of the items, reduce bottom deformation, and improve the structural stability and load-bearing reliability of the packaging plastic bag when loaded with heavy objects.
[0012] In a preferred embodiment, the load-bearing reinforcement component further includes: side reinforcing ribs, installed on the side edge of the bag body, and having pleated structures evenly distributed thereon.
[0013] The technical advantage of adopting the above-mentioned further solution is that the uniformly wrinkled structure on the side reinforcing ribs can naturally unfold or conform to the side as the bag is subjected to force. This design can flexibly adapt to changes in loading capacity, enhance the load-bearing strength of the sides, reduce deformation under stress, and, in conjunction with the bottom support ring, further improve the overall structural stability and load-bearing adaptability of the packaging plastic bag.
[0014] In a preferred embodiment, the bag body adopts a multi-layer composite structure, including a first composite layer, a second composite layer and a third composite layer; wherein, the first composite layer is a modified PPE material, the second composite layer is a high-strength fiber reinforcement layer, and the third composite layer is a biodegradable PPE composite material.
[0015] The technical effects of adopting the above-mentioned further solutions are: the modified layer improves the basic performance, the fiber reinforcement layer strengthens the structural strength, and the biodegradable layer takes into account environmental protection. The three layers work together to give the bag good toughness, load-bearing capacity and environmental protection properties, thus optimizing the durability and ecological adaptability of industrial packaging.
[0016] In a preferred embodiment, the bag body is fixedly connected to two nylon cable ties, and the nylon cable ties are connected to fixed buttons and have buckle holes at their ends.
[0017] The technical advantage of adopting the above-mentioned further solution is that the nylon cable ties are equipped with fixing buttons and end buckles, which can be used to further reinforce the bag opening by fastening the buttons and buckles. This design can further tighten and fix the bag on top of the zipper seal, preventing items from falling off during handling, enhancing the sealing and stability of the packaging, and improving the safety of transporting and storing industrial goods.
[0018] In a preferred embodiment, the base of the handle extends laterally and is connected to two reinforcing tabs, which are heat-sealed to the bag body.
[0019] The technical effect of adopting the above-mentioned further solution is that the two reinforcing pieces extending laterally from the base of the handle are heat-sealed to the bag body, which can disperse the local pressure when the handle is under force and strengthen the connection between the handle and the bag body. This design reduces the risk of tearing at the base of the handle due to lifting heavy objects, improves the load-bearing stability of the handle, and, together with other reinforcing structures, further ensures the structural reliability of the packaged plastic bag during handling.
[0020] In a preferred embodiment, the bag body has an external label slot, and the label slot is made of transparent plastic.
[0021] The technical advantages of adopting the above-mentioned further solution are: the transparent plastic label slot allows for easy insertion of label information cards. The transparent material ensures that the content is clearly visible, facilitating quick identification of information such as the type and specifications of items inside the packaging, improving the efficiency of item classification management in industrial warehousing and transportation, reducing identification errors, and enhancing the practicality and management convenience of the packaging.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model enhances strength through a multi-layered load-bearing reinforcement design. Specifically, the inner ring of the bottom surface has a built-in memory metal wire, which provides stable support to the bottom through its elasticity and shape memory function, preventing heavy objects from damaging the bottom surface; the side reinforcing ribs on the side edges have a pleated structure, which naturally unfolds under force to enhance the side load-bearing capacity, and closes to the side without taking up space when not in use; the reinforcing piece at the base of the handle is heat-sealed to the bag body, greatly improving the load-bearing stability of the handle and preventing it from falling off during handling. At the same time, in the multi-layered composite structure of the bag body, the high-strength fiber reinforcement layer further enhances the overall tensile and tear resistance, allowing the plastic bag to stably support heavy industrial items.
[0023] This utility model utilizes a zipper for quick opening and closing, ensuring reliable sealing and preventing items from falling out. The external nylon cable ties, with their securing buttons and snap holes, further reinforce the seal when there are many items. Functionally, multiple internal folded, layered cavities are flexibly separated by snap fasteners, allowing for the categorized storage of different items and preventing damage from crushing. An external transparent label slot allows for the insertion of labels, facilitating quick and easy identification of internal items and improving retrieval efficiency. These designs enable the plastic bag to combine reliable sealing, convenient operation, and categorized storage, meeting the diverse needs of industrial packaging. Attached Figure Description

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0027] Please see Figure 1-5 This utility model provides a technical solution: a PPE industrial packaging plastic bag, the specific concept of which is as follows: The industrial packaging plastic bag includes a bag body 1, and a handle 2 is fixedly connected to the upper middle part of each side of the bag body 1 to facilitate handling. Two reinforcing pieces 3 extend from the base of the handle 2 to the side. These reinforcing pieces 3 are tightly connected to the bag body 1 by heat sealing. This connection method can greatly enhance the firmness of the connection between the handle 2 and the bag body 1, and effectively prevent the handle 2 from falling off the bag body 1 when bearing weight. Zippers 5 are installed on both sides of the opening at the top of the bag body 1. The bag can be easily opened and closed by pulling the zipper 5. The zipper 5 has good sealing performance and can prevent the items inside the bag from falling out. Two nylon cable ties 8 are also fixedly connected to the outside of the bag body 1. The nylon cable ties 8 are connected to the fixing buttons 9, and the ends of the buttons 8 are provided with buckle holes 10. When there are many items in the bag or when the bag needs to be additionally fixed, the fixing buttons 9 can be fastened into the buckle holes 10 to further ensure the sealing and stability of the bag. Example
[0028] like Figure 1-5 As shown in Example 1, this PPE industrial packaging plastic bag is further equipped with a multi-layered component to achieve classified storage of different items within the same package. The specific idea is as follows: The layering assembly includes a folding layering cavity 7 and a snap fastener 11. One side of the folding layering cavity 7 is fixedly connected to the inner side of the bag body 1, and the snap fastener 11 is respectively set on one side of the folding layering cavity 7 and the inner side of the bag body 1.
[0029] When items need to be sorted and stored, the folded compartment 7 can be unfolded and secured in a suitable position inside the bag body 1 by fastening the snap fastener 11, thereby dividing the interior of the bag body 1 into multiple independent compartments; when no stratification is needed, the snap fastener 11 can be unfastened and the folded compartment 7 can be folded up without taking up too much space.
[0030] Furthermore, it should be noted that the bag body 1 adopts a multi-layer composite structure, including a first composite layer 101, a second composite layer 102, and a third composite layer 103. The first composite layer 101 is a modified PPE material, possessing good corrosion resistance and abrasion resistance; the second composite layer 102 is a high-strength fiber reinforcement layer, which significantly improves the overall strength of the bag body 1; and the third composite layer 103 is a biodegradable PPE composite material, enabling the plastic bag to gradually degrade in the natural environment after disposal, reducing environmental pollution.
[0031] In addition, the exterior of the bag body 1 is provided with a label slot 12. The label slot 12 is made of transparent plastic, which makes it easy to insert a label to mark the information of the items inside the bag, so as to facilitate quick identification of the items inside the bag. Example
[0032] like Figure 1-5 As shown, based on Embodiment 1 and Embodiment 2, this PPE industrial packaging plastic bag is also equipped with load-bearing reinforcement components to improve the load-bearing capacity of the bag. The specific idea is as follows: The load-bearing reinforcement components include an annular elastic support ring 4 and side reinforcing ribs 6. The annular elastic support ring 4 is installed on the inner side of the bottom surface of the bag body 1, and its diameter is consistent with the short side of the bottom surface of the bag body 1. A shape memory wire is embedded inside the annular elastic support ring 4. The shape memory wire has good elasticity and shape memory function, enabling the annular elastic support ring 4 to effectively support the bottom surface of the bag body 1. When heavy items are placed inside the bag, it can prevent the bottom surface of the bag from breaking due to excessive force.
[0033] Side reinforcing ribs 6 are installed on the side edges of the bag body 1. The side reinforcing ribs 6 have evenly distributed pleated structures that can naturally unfold or conform to the side of the bag body 1 depending on the stress it experiences. When the bag is filled with items, the side of the bag body 1 is subjected to stress, and the pleated structures on the side reinforcing ribs 6 will naturally unfold, thereby enhancing the load-bearing capacity of the side. When the bag contains fewer items and the side stress is less, the pleated structures will conform to the side without taking up extra space. Through the combined action of the annular elastic support ring 4 and the side reinforcing ribs 6, the load-bearing capacity of the plastic bag is greatly improved, extending its service life.
[0034] Working principle: This device is a PPE industrial packaging plastic bag. In use, first pull the zippers 5 on both sides of the opening at the top of the bag body 1 to open the bag. If items need to be stored separately, the internal folding compartment 7 can be unfolded. The folding compartment 7 is then secured by fastening one side of the compartment with the snap fastener 11 on the inside of the bag body 1, thus dividing the bag's interior into multiple independent chambers for the separate storage of different items. When no separation is needed, the snap fastener 11 can be unfastened, and the folding compartment 7 can be folded and fitted to the inside, saving space.
[0035] After filling the bag with items, zip up 5 to seal it. If there are many items, the fastening buttons 9 on the two nylon cable ties 8 on the outside of the bag body 1 can be fastened into the end buckle holes 10 to further reinforce the bag. When carrying, lift the bag by the handles 2 on the upper middle part of both sides. The reinforcing piece 3 extending from the base of the handle 2 is heat-sealed to the bag body 1, which enhances the load-bearing stability of the handle 2 and prevents it from falling off.
[0036] When items are placed inside the bag, the side of the bag body 1 is subjected to force, and the pleated structure on the side reinforcing rib 6 will naturally unfold, thereby enhancing the load-bearing capacity of the side. When there are fewer items in the bag and the side is subjected to less force, the pleated structure will fit against the side without taking up extra space. The ring elastic support ring 4 can prevent the bottom of the bag from being damaged due to excessive force when heavier items are placed inside.
[0037] Meanwhile, the external transparent sign slot 12 allows for the insertion of a sign, facilitating the identification of internal items. The above is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may utilize the disclosed technical content to make changes or modifications to create equivalent embodiments applicable to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, shall still fall within the protection scope of this utility model's technical solution.
