[0002] Composite paper is made by bonding paper and paperboard with other plastics, aluminum foil, cloth, etc. using adhesives.

Metallized film is a composite flexible packaging material formed by coating an extremely thin layer of metallic aluminum onto the surface of a plastic film using a special process.

[0003] In the existing technology, the composite paper in composite paperboard is mostly arranged in a wavy single layer in the composite paper layer. Paperboard with this structure has poor strength and weak pressure resistance. During use, the composite paper often deforms due to stress. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure-resistant aluminized composite paper. The addition of a pressure-resistant layer enhances the overall stability of the composite paper, enabling it to better maintain its structural integrity when subjected to external forces. Since the pressure-resistant layer improves the pressure resistance and overall stability of the composite paper, it also extends the service life of the composite paper and improves its durability and reliability.

[0005] This utility model provides the following technical solution: a pressure-resistant aluminum-coated composite paper, comprising: a base paper layer body, a pressure-resistant layer provided on the outer side of the base paper layer body, a connecting layer provided at one end of the pressure-resistant layer away from the base paper layer body, an aluminum-coated layer fixedly connected at one end of the connecting layer away from the pressure-resistant layer, and a surface layer fixedly connected at one end of the aluminum-coated layer away from the connecting layer.

[0006] The pressure-resistant layer is used to increase the pressure resistance of the base paper layer. The pressure-resistant layer includes two sets of pressure-resistant plates located between the base paper layer and the connecting layer. A fixing plate is provided between the two sets of pressure-resistant plates. Multiple sets of pressure-resistant sheets are fixedly connected to both ends of the fixing plate and inside the two sets of pressure-resistant plates. Connecting strips are provided inside the pressure-resistant sheets.

[0007] As a preferred embodiment of this utility model, the two sets of pressure-resistant plates are fixedly connected to the base paper layer and the connecting layer, respectively, and the two ends of the pressure-resistant sheet are fixedly connected to the pressure-resistant plate and the fixing plate, respectively.

[0008] As a preferred embodiment of this utility model, multiple pressure-resistant plates are distributed at equal intervals on the outer side of the fixing plate, and the pressure-resistant plates are designed in a trapezoidal structure.

[0009] As a preferred embodiment of this utility model, multiple sets of first buffer plates are fixedly connected to both ends of the connecting strip and between the pressure-resistant plate and the fixing plate. A second buffer plate is fixedly connected inside the first buffer plate. Both the first buffer plate and the second buffer plate are designed with a semi-circular structure.

[0010] As a preferred embodiment of this utility model, the connecting strip has two sets of support plates fixedly connected inside, and the support plates have a wave-shaped structure design.

[0011] As a preferred embodiment of this utility model, multiple sets of elastic strips are fixedly connected to the inner side of the support plate, and the multiple sets of elastic strips are distributed at equal intervals inside the support plate.

[0012] As a preferred embodiment of this utility model, a bottom layer is fixedly connected to the end of the base paper layer away from the pressure-resistant layer, and the base paper layer, pressure-resistant layer, connecting layer, aluminum-plated layer and surface layer are fixedly connected to each other by composite adhesive.

[0013] The beneficial effects of this utility model are as follows: Through the design of the pressure-resistant layer, the design principle of which mainly lies in improving the pressure resistance of the composite paper through the combination of multiple structures. The pressure-resistant sheet has a trapezoidal structure design and is evenly distributed on the outside of the fixing plate. These structures work together to enable the pressure-resistant layer to better disperse pressure when subjected to external force, avoiding damage caused by excessive local pressure. Through the combined design of the pressure-resistant plate, fixing plate, and pressure-resistant sheet, the pressure-resistant layer can significantly improve the pressure resistance of the composite paper. The trapezoidal structure design of the pressure-resistant sheet can better disperse pressure when subjected to force, avoiding damage caused by excessive local pressure. When the composite paper is impacted by external force, the first and second buffer sheets can first absorb and disperse the impact force, reducing the damage to the pressure-resistant layer. The direct impact of the compression layer protects the integrity of the pressure-resistant layer structure. The design of the double-layer semi-circular buffer sheet effectively improves the impact resistance of the composite paper and increases the safety of use. The corrugated support sheet can undergo elastic deformation under stress, converting external force into the internal energy of the support sheet, thereby reducing the damage of external force to the overall structure of the composite paper. The design of the corrugated support sheet not only improves the pressure resistance of the composite paper, but also increases its flexibility and service life. The addition of the pressure-resistant layer enhances the overall stability of the composite paper, enabling it to better maintain its structural integrity when subjected to external forces. Because the pressure-resistant layer improves the pressure resistance and overall stability of the composite paper, it also extends the service life of the composite paper and improves its durability and reliability.

[0019] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example:

[0021] like Figures 1 to 4 As shown, a pressure-resistant aluminized composite paper includes: a base paper layer body 1, a pressure-resistant layer 2 provided on the outer side of the base paper layer body 1, a connecting layer 3 provided at one end of the pressure-resistant layer 2 away from the base paper layer body 1, an aluminized layer 4 fixedly connected to one end of the connecting layer 3 away from the pressure-resistant layer 2, and a surface layer 5 fixedly connected to one end of the aluminized layer 4 away from the connecting layer 3.

[0022] The pressure-resistant layer 2 is used to increase the pressure resistance of the base paper layer body 1. The pressure-resistant layer 2 includes two sets of pressure-resistant plates 6 located between the base paper layer body 1 and the connecting layer 3. A fixing plate 7 is provided between the two sets of pressure-resistant plates 6. Multiple sets of pressure-resistant sheets 8 are fixedly connected to both ends of the fixing plate 7 and located inside the two sets of pressure-resistant plates 6. A connecting strip 9 is provided inside the pressure-resistant sheet 8.

[0023] In this embodiment, two sets of pressure-resistant plates 6 are fixedly connected to the base paper layer 1 and the connecting layer 3, respectively. The two ends of the pressure-resistant sheet 8 are fixedly connected to the pressure-resistant plate 6 and the fixing plate 7, respectively. The pressure-resistant sheet 8 enhances the overall stability and uniform stress distribution of the pressure-resistant layer 2. The pressure-resistant sheet 8 has a trapezoidal structure design. Multiple sets of pressure-resistant sheets 8 are evenly distributed on the outside of the fixing plate 7. The trapezoidal structure design of the pressure-resistant sheet 8 allows it to better disperse pressure when subjected to force, improving its pressure resistance. The trapezoidal structure design of the pressure-resistant sheet 8 allows it to gradually disperse pressure to the pressure-resistant plate 6 and the fixing plate 7 through the trapezoidal slope when subjected to external force, avoiding damage caused by excessive local pressure. The evenly distributed pressure-resistant sheets 8 further enhance the overall pressure resistance of the pressure-resistant layer 2. Through the trapezoidal structure design of the pressure-resistant sheet 8 and the evenly distributed arrangement, the pressure resistance of the composite paper is significantly improved, and its service life is extended.

[0024] In this embodiment, multiple sets of first buffer sheets 10 are fixedly connected to both ends of the connecting strip 9 and between the pressure-resistant sheet 8 and the fixing plate 7. A second buffer sheet 11 is fixedly connected inside the first buffer sheet 10. Both the first buffer sheet 10 and the second buffer sheet 11 have a semi-circular structure design. When the composite paper is impacted by external force, the first buffer sheet 10 and the second buffer sheet 11 can first absorb and disperse the impact force, reduce the direct impact on the pressure-resistant layer 2, and protect the integrity of the pressure-resistant layer 2 structure. Through the design of the double-layer semi-circular buffer sheet, the impact resistance of the composite paper is effectively improved and the safety of use is increased.

[0025] In this embodiment, two sets of support plates 12 are fixedly connected inside the connecting strip 9. The support plates 12 have a wave-shaped structure design. When subjected to force, the wave-shaped support plates 12 can undergo elastic deformation, converting the external force into the internal energy of the support plates 12, thereby reducing the damage of the external force to the overall structure of the composite paper. The design of the wave-shaped support plates 12 not only improves the pressure resistance of the composite paper, but also increases its flexibility and service life.

[0026] In this embodiment, multiple sets of elastic strips 13 are fixedly connected to the inner side of the support piece 12. The multiple sets of elastic strips 13 are evenly distributed inside the support piece 12. The setting of elastic strips 13 further enhances the elasticity and compressive strength of the support piece 12, so that the composite paper can better maintain the stability of its overall structure when subjected to external force. The elastic strips 13 and the support piece 12 work together to form a structural system with stronger compressive strength. When external force is applied to the composite paper, the elastic strips 13 can respond quickly and absorb energy, thereby protecting the overall structure of the composite paper from damage. By adding the design of elastic strips 13, the compressive strength and overall stability of the composite paper are further improved, meeting the higher requirements of the application scenarios.

[0027] In this embodiment, a bottom layer 14 is fixedly connected to the end of the base paper layer 1 away from the pressure-resistant layer 2. The base paper layer 1, pressure-resistant layer 2, connecting layer 3, aluminum-plated layer 4, and surface layer 5 are fixedly connected to each other by a composite adhesive. The bottom layer 14 enhances the bottom strength of the composite paper, enabling the composite paper to better maintain the stability of its overall structure during use. At the same time, the use of composite adhesive ensures a firm connection between the layers, improving the overall strength and durability of the composite paper. The use of the bottom layer 14 and composite adhesive further enhances the overall strength and durability of the composite paper, improving its reliability and service life in practical applications.
