Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0018] Embodiment one:

[0019] As Figs. 1-3 The utility model discloses a kind of high tenacity packing belts, including packing belt body 1, packing belt body 1 includes tenacity layer 2 and the reinforcing layer 3 being set in the upper and lower both sides of tenacity layer 2, tenacity layer 2 includes framework 4 and filling layer 5 with secondary integrated molding of framework 4, framework 4 includes main bone 6 and the bone 7 of continuous setting in the both sides of main bone 6, packing belt body 1 outside is wrapped with protective layer 8.

The material of reinforcing layer 3 is PP material, and reinforcing layer 3 is fixed by adhesive with tenacity layer 2.

[0020] Through the technical scheme, the packing belt body 1 comprises a toughness layer 2 and a reinforcing layer 3, the reinforcing layer 3 is arranged on the upper and lower sides of the toughness layer 2, the tensile property of the packing belt body 1 is improved, the toughness layer 2 comprises a framework 4 and a filling layer 5, the framework 4 and the filling layer 5 are prepared by using a secondary integral forming process, and the framework 4 improves the toughness of the packing belt.

[0021] The utility model discloses a packing belt body 1 outside is wrapped with the protective layer 8, and the protective layer 8 is wrapped with packing belt, prevents packing belt burr to scratch the skin.

[0022] Example two:

[0023] As Figs. 1-3 The utility model discloses a packing belt body 1 by three layers structure composition. The middle is toughness layer 2, and the upper and lower sides are provided with reinforcing layer 3 respectively. Toughness layer 2 is composed of framework 4 and filling layer 5. Framework 4 and filling layer 5 are closely combined together through secondary integral forming process, and form complete toughness layer 2 structure. Framework 4 includes the main bone 6 in the center and the bone spur 7 continuously arranged on the both sides of main bone 6. Main bone 6 plays the main support and tensile role, provides longitudinal strength. Bone spur 7 enhances the transverse strength and stability. Filling layer 5 fills in the gap of framework 4 and forms the integrated structure with framework 4. Filling layer 5 all has strong tensile property. Reinforcing layer 3 is arranged on the upper and lower sides of toughness layer 2, and further enhances the tensile property of packing belt. Reinforcing layer 3 is closely combined with toughness layer 2, and forms multilayer composite structure. This multilayer structure design significantly improves the overall strength and toughness of packing belt. On the outermost side of packing belt body 1, there is a protective layer 8. Protective layer 8 is coated on the surface of packing belt and plays a protection role. Protective layer 8 reduces the burr that can be generated on the surface of packing belt, reduces the risk of causing harm to operators in the use process. At the same time, protective layer 8 also protects packing belt body 1, prolongs the service life of packing belt. This structure design solves the problems that the existing packing belt is easy to break and easy to produce creases. The framework 4-filling layer 5 structure of toughness layer 2 provides good strength and ductility, the reinforcing layer 3 enhances the tensile property, and the protective layer 8 improves the use safety. Each structure layer is closely combined through glue and forms an integral whole. In the use process of packing belt, each structure layer cooperates and bears the external stress. When subjected to tension, the reinforcing layer 3 first bears the tensile stress, and the framework 4 structure of toughness layer 2 provides the main support force. This multilayer cooperative working mode makes the packing belt have excellent tensile strength and toughness. Even under a larger stress, the packing belt is not easy to break or produce permanent deformation.

[0024] Example three:

[0025] As Figs. 1-3As shown, this invention incorporates reinforcing ribs 9 on both the main frame 6 and the spikes 7 to enhance the toughness of the skeleton 4. The reinforcing ribs 9 on the main frame 6 are evenly distributed along its length, forming a multi-protruding structure. These reinforcing ribs 9 strengthen the longitudinal strength of the main frame 6, enabling it to withstand greater longitudinal stress. The reinforcing ribs 9 on the spikes 7 are arranged along their extension direction, forming a mesh-like structure. This mesh-like reinforcing rib structure significantly improves the lateral strength and stability of the spikes 7. The reinforcing ribs 9 make the overall structure of the skeleton 4 more robust, further improving the tensile strength and toughness of the strapping. When the strapping is subjected to bending, the reinforcing ribs 9 effectively disperse stress, reducing stress concentration and lowering the risk of skeleton 4 breakage. In practical use, the reinforcing ribs 9 increase the rigidity of the skeleton 4, allowing the strapping to maintain good shape stability under stress. Furthermore, the reinforcing ribs 9 improve the bending resistance of the skeleton 4, reducing the possibility of permanent deformation or breakage of the strapping during repeated bending. The reinforcing rib 9 provides the skeleton 4 with better stress dispersion capabilities. When the strapping is subjected to localized impact or compression, the reinforcing rib 9 can quickly transfer the stress to the surrounding area, preventing localized damage caused by stress concentration. The presence of the reinforcing rib 9 also gives the skeleton 4 better fatigue resistance, allowing the strapping to maintain good performance even under long-term repeated use.

[0026] Example 4:

[0027] like Figs. 1-3 As shown, the filler layer 5 of this invention is made of PET (polyethylene terephthalate). PET material has excellent mechanical properties and chemical stability, making it an ideal choice for manufacturing high-performance strapping. The filler layer 5 and the skeleton 4 are tightly bonded together through a secondary integrated molding process, forming a complete tough layer 2 structure. The PET filler layer 5 has good ductility and elastic recovery, capable of undergoing moderate deformation when the strapping is subjected to tensile force and quickly returning to its original shape after the force is unloaded. This characteristic provides good cushioning during use, reducing the risk of breakage due to impact or sudden stress. Simultaneously, the PET filler layer 5 also has excellent wear resistance and anti-aging properties, maintaining stable physical and chemical properties over long-term use. The large bonding area and high bonding strength between the filler layer 5 and the skeleton 4 form an integrated tough layer 2 structure. When the strapping is under stress, the filler layer 5 works collaboratively with the skeleton 4 to jointly bear the externally applied stress. The presence of the filler layer 5 not only increases the cross-sectional area of ​​the strapping and improves its overall strength but also plays a role in stress dispersion, reducing stress concentration.

[0028] Example 5:

[0029] like Figs. 1-3As shown, the protective layer 8 completely wraps the outside of the packaging tape body 1, forming a soft and elastic protective barrier. The synthetic rubber has good toughness and wear resistance. During the packaging process, even if the packaging tape is squeezed or rubbed, the synthetic rubber protective layer 8 can maintain its integrity and is not prone to damage or cracking. The design of the protective layer 8 significantly reduces the roughness of the surface of the packaging tape, making the entire packaging tape surface smoother and more attractive. When the operator holds or contacts the packaging tape, the synthetic rubber protective layer 8 can effectively block the burrs or sharp edges that may exist on the packaging tape body 1, preventing skin scratches. At the same time, the synthetic rubber has a certain friction coefficient, enhancing the adhesion between the packaging tape and the packaged items, reducing the likelihood of the packaging tape slipping during use.

[0030] Example six:

[0031] As Figs. 1-3 shown, the reinforcing layer 3 is made of PP material, which is fixed by adhesive with the toughness layer 2. The reinforcing layer 3 is arranged on the upper and lower sides of the toughness layer 2, forming a sandwich structure. The PP material has excellent mechanical properties, including high strength, high toughness and good wear resistance, which enables the reinforcing layer 3 to significantly improve the overall tensile performance of the packaging tape. During the manufacturing process, the PP material is first processed into a thin sheet, and then the adhesive is uniformly applied on the contact surface of the PP material reinforcing layer 3 and the toughness layer 2 through a precisely controlled gluing process. Subsequently, the reinforcing layer 3 and the toughness layer 2 are tightly bonded together through a hot pressing or cold pressing process, forming an integral structure. This bonding method ensures the firm connection between the reinforcing layer 3 and the toughness layer 2, avoiding the problem of interlayer separation during use.
