[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 In this embodiment, a composite seamless packaging hose based on a multi-daylight color-changing effect sheet comprises an inner layer 1, an isolation layer 2 is arranged on the outer side of the inner layer 1, and the isolation layer 2 is aluminized polyethylene. Aluminized polyethylene is a composite material composed of a polyethylene substrate coated with an aluminum film. Aluminized polyethylene has excellent gas and water vapor barrier properties, can effectively protect the packaged items from the influence of external gas and water vapor, has good sealing performance and good light transmittance, and can better meet the requirements of specialization, personalization, and anti-counterfeiting of the appearance of the hose;

[0019] An insulating layer 3 is provided on the outside of the isolation layer 2. The insulating layer 3 is made of silica gel, which is a colloidal substance composed of silicon dioxide and water. Silicone has excellent high temperature resistance and can work stably for a long time at a high temperature. It can effectively resist heat radiation and conduction in a high temperature environment and protect the medium inside the hose from heat.

[0020] A reinforcing layer 4 is provided on the outside of the heat insulating layer 3. The reinforcing layer 4 is plastic fiber, which is a fiber made of synthetic polymers. The plastic fiber increases the strength and wear resistance of the hose, makes the hose more durable and stretch-resistant, reduces the risk of wear and damage of the hose during use, and can increase the pressure resistance of the hose, making the hose less likely to deform or break when subjected to external pressure. The plastic fiber layer can improve the anti-aging performance of the hose and extend the service life of the hose;

[0021] A flame retardant layer 5 is provided on the outside of the reinforcing layer 4. The flame retardant layer 5 is polytetrafluoroethylene. Polytetrafluoroethylene is a polymer material with excellent chemical stability and heat resistance. It is a polymer made by polymerization of fluorine atoms and ethylene monomers. It has excellent heat resistance and can work stably for a long time at high temperatures. Its melting point is about 327°C, and its short-term high temperature resistance reaches 260°C.

[0022] A color-changing layer 6 is provided on the outside of the flame-retardant layer 5. The color-changing layer 6 is an optical film. An optical film is a film material with specific optical properties, which is usually used to regulate the propagation, reflection, transmission and absorption of light. The optical film can be designed to have transmission, reflection or absorption characteristics of a specific wavelength as needed. The optical film is usually stacked by multiple layers of thin films. The thickness and refractive index of each layer of film are precisely designed to achieve the regulation of light of different wavelengths and angles, thereby presenting multiple daylight color-changing effects. A reflective layer 7 is provided on the outside of the color-changing layer 6. The reflective layer 7 is an anti-reflective coating. The design and preparation of the anti-reflective coating usually involves the stacking of multiple layers of thin films. The thickness and refractive index of each layer of film are precisely designed and controlled. By rationally designing the optical parameters of the coating, the reflectivity of light within a specific wavelength range can be reduced, thereby improving the transmittance of the optical device. The setting of the reflective layer 7 can be used to reduce reflection and improve transmittance.

[0023] An outer layer 8 is provided on the outside of the reflective layer 7, and the outer layer 8 and the inner layer 1 are both polyethylene. Polyethylene is easy to be processed into various shapes and can be made into hoses by extrusion molding. Therefore, it is suitable for packaging hoses of various shapes and sizes. Polyethylene has good acid and alkali resistance and chemical stability, so it can remain stable when in contact with chemicals such as cosmetics and medicines, and is not easily susceptible to chemical corrosion. The polyethylene hose can have good transparency, making the appearance of the packaged items clearer and more visible. At the same time, the polyethylene hose is relatively light and easy to carry and use.

[0024] In this embodiment, by setting the color-changing layer 6, under the composition of the multi-layer optical film, it is possible to control light of different wavelengths and angles, thereby presenting multiple daylight color-changing effects, and the set radiation layer 7 can reduce reflection and increase transmittance, thereby enhancing the unique visual effect of the packaging hose and increasing product recognition.

[0026] Material preparation: Prepare various required raw materials, including inner layer materials, middle layer materials, outer layer materials, etc. These materials usually include plastic film, aluminum foil, paper, polyethylene, polyvinyl chloride, etc.

[0027] Compounding: Bonding different materials together through compounding process to form a multi-layer structure. The compounding process can be hot pressing compounding, coating compounding, co-extrusion compounding and other methods.

[0028] Molding: The composite material is molded, usually by extrusion molding or blow molding, into a tubular structure.

[0029] Bag making: Cut and seal the tubular structure to make a hose of the required length.

[0030] Printing: Print the hose as needed, with product information, trademarks, patterns, etc.

[0031] Inspection: Carry out quality inspection on the manufactured hose, including appearance quality, dimensional accuracy, physical properties, etc.

[0032] Packaging: Qualified hoses are packaged, usually in roll packaging or finished product packaging.

[0033] The working principle of the above embodiment is:

[0034] By setting up the isolation layer 2, under the action of aluminum-plated polyethylene, water, oxygen, gas, etc. can be blocked. At the same time, it also has the characteristics of flame retardancy, corrosion resistance, good air tightness, etc., which improves the practicability of the packaging hose; and the setting of the heat insulation layer 3 can effectively resist the heat radiation and conduction in a high temperature environment through silica gel, and protect the medium inside the hose from being affected by heat; the setting of the flame retardant layer 5 can effectively resist high temperature and flame, and protect the medium inside the hose from being affected. The setting of the color-changing layer 6, under the composition of the multi-layer optical film, can realize the regulation of light of different wavelengths and angles, thereby presenting multiple daylight color-changing effects, and the setting of the radiation layer 7 can reduce reflection and improve transmittance, thereby enhancing the unique visual effect of the packaging hose and increasing product recognition.
