[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides a high-strength puff pastry lettering film, such as Figure 1-4 As shown, the high-strength choux pastry lettering film includes: a backing paper 1; a plurality of choux pastry sheets 3 that are adhered to the backing paper 1 and can be bonded to rigid surfaces and textile fabrics; an adhesive sheet 2 that is adhered to the backing paper 1 for connecting the backing paper 1 and the choux pastry sheets 3; and a thermal adhesive sheet 4 disposed on the side of the choux pastry sheet 3 away from the backing paper 1, wherein the thermal adhesive sheet 4 and the backing paper 1 cooperate to protect the choux pastry sheet 3.

[0020] In this embodiment, the backing paper 1 serves as the cornerstone of the entire structure, providing stable support for the puff film 3. It not only ensures the stability of the puff film 3 during processing and transportation but also facilitates subsequent pasting operations. The selection of the backing paper 1 was carefully considered to ensure it possesses sufficient strength while allowing for easy peeling when needed without causing any damage to the puff film 3. The puff film 3 is a core component of the high-strength puff lettering film. These films are made of special materials with excellent flexibility and abrasion resistance. They can adhere tightly to hard surfaces and textiles, ensuring the clarity and durability of text, patterns, and other information. Simultaneously, the puff film 3 also possesses good elastic recovery capabilities, adapting to fabric stretching and deformation to a certain extent, thereby effectively reducing damage caused by fabric pulling. To minimize the risk of breakage, multiple puff-shaped film sheets 3 are arranged in a plane from point to surface, further increasing their adaptability to elastic fabrics and preventing them from being easily torn and falling off. The adhesive sheet 2 not only needs to have strong adhesive force to ensure that the puff-shaped film sheet 3 can be firmly attached to the backing paper 1, but also needs to maintain stable adhesion during subsequent use to prevent the puff-shaped film sheet 3 from falling off or shifting. The thermal adhesive sheet 4 is another important innovation of the high-strength puff-shaped lettering film. It is set on the side of the puff-shaped film sheet 3 away from the backing paper 1, and together with the backing paper 1, it forms an all-round protection for the puff-shaped film sheet 3. The thermal adhesive sheet 4 can respond to specific temperature stimuli to achieve close adhesion and separation with the puff-shaped film sheet 3, which is convenient to maintain the protection of the puff-shaped film sheet 3 when hot-pressing. The thermal adhesive sheet 4 loses its adhesiveness after being heated, which also facilitates the disassembly work.

[0021] In a further preferred embodiment of the present invention, the thermal film 4 has a groove 5 on the side away from the backing paper 1, and a pinch piece 6 for providing a pulling force point is installed in the groove 5. The thickness of the pinch piece 6 is the same as the height of the groove 5.

[0022] In this embodiment, the main function of the thermal film 4 is to respond to temperature stimulation and achieve a tight fit with the puff film 3, thereby enhancing the stability and durability of the overall structure. Based on the original design, this embodiment adds a groove 5 on the side of the thermal film 4 away from the backing paper 1. In practical applications, users often need to make precise cuts or positioning on the puff lettering film. The introduction of the groove 5 provides users with an intuitive and easy-to-identify operating area. The design of the pinch piece 6 fully considers the principles of ergonomics. Its shape, size and position have been carefully calculated to ensure that users can hold it easily and comfortably and easily tear off the thermal film 4, thereby fully exposing the puff film 3. At the same time, the thickness of the pinch piece 6 is exactly the same as the height of the groove 5. This detail not only ensures the compactness and aesthetics of the structure, but also avoids the inconvenience or damage risk caused by the protrusion of the pinch piece 6.

[0023] In a further preferred embodiment of the present invention, a double-sided adhesive 8 is attached to the side of the thermal film 4 near the pinch piece 6, and a top liner paper 9 for increasing tear resistance is attached to the double-sided adhesive 8.

[0024] In this embodiment, the choice of double-sided adhesive 8 is crucial. It must not only possess strong adhesion to ensure a firm bond with the thermal film 4 and the top liner 9, but also have a certain degree of elasticity and weather resistance to adapt to usage requirements in different environments. In practical applications, the double-sided adhesive 8 not only serves a connecting function but also subtly enhances the overall structural strength of the Puff lettering film, enabling it to exhibit higher tear resistance when faced with external tearing forces. The introduction of the top liner 9 further reinforces this design. When the Puff lettering film is installed on a rigid surface... When applied to flat surfaces or textiles, the top liner 9 effectively disperses external forces, reducing the risk of damage caused by excessive local stress. The combination of the top liner 9 and the double-sided adhesive 8 not only enhances the structural strength of the Puff lettering film but also provides users with a more convenient operating experience. During the installation of the Puff lettering film, users only need to peel off the top liner 9 to expose the thermal adhesive film 4. At this point, the adhesive film 2 is pasted onto the flat surface or textile, and then hot-pressed to stabilize the Puff film 3 on the flat surface or textile. The thermal adhesive film 4 loses its adhesiveness when heated and can be easily peeled off.

[0025] In a further preferred embodiment of this utility model, both the thermal film 4 and the pinch sheet 6 are provided with a waterproof film 7 for assisting in the tearing of the double-sided adhesive 8, and the puff film 3 is made of TPU material.

[0026] In this embodiment, the main function of the waterproof membrane 7 is to assist the tearing process of the double-sided adhesive 8, ensuring that the user can easily and cleanly separate the double-sided adhesive 8 when removing the top backing paper 9 and installing the Puff lettering film, avoiding problems such as adhesive residue or damage to the Puff lettering film. More importantly, the waterproof membrane 7 also has certain waterproof and moisture-proof properties, which can protect the Puff lettering film from moisture erosion to a certain extent and extend its service life. The Puff film 3 is made of TPU (thermoplastic polyurethane) material. TPU material is known for its excellent elasticity, wear resistance and weather resistance, making it very suitable for making Puff lettering films that need to withstand external tearing and long-term exposure to outdoor environments. Compared with traditional materials, TPU material not only has higher strength and toughness, but also maintains good flexibility and plasticity, making it easier to apply the Puff lettering film to various complex curved surfaces. In addition, TPU material also has a certain self-healing ability. Even if minor scratches or damage occur during use, it can self-repair to a certain extent, further extending the service life of the Puff lettering film.

[0027] In a further preferred embodiment of this utility model, the ratio of the spacing length of the plurality of puff pastry sheets 3 to the inner diameter length of the puff pastry sheet 3 is 1:5, and the bottom liner paper 1 and the top liner paper 9 are made of homopolymer polyvinyl chloride.

[0028] In this embodiment, the ratio of the spacing length of the multiple puff-shaped film pieces 3 to their inner diameter length is precisely set to 1:5. This ratio is not chosen arbitrarily, but is based on in-depth analysis and calculation of product performance and user needs. Through this design, the spacing between the puff-shaped film pieces 3 is reasonably controlled, ensuring sufficient visual impact while avoiding a loose overall structure due to excessive spacing. At the same time, the inner diameter length of the puff-shaped film pieces 3 is also optimized, enabling them to better adapt to the engraving needs of various texts and patterns, ensuring the clarity and accuracy of the engraving effect. The layout design also brings significant improvements in practicality. During the installation and use of the puff-shaped lettering film, the reasonable spacing... The layout of the PVC film sheet 3 not only improves installation efficiency but also effectively reduces material waste and lowers production costs. In addition, by optimizing the spacing and inner diameter-to-length ratio of the PVC film sheet 3, the tear resistance of the PVC lettering film can be improved to a certain extent, enabling it to exhibit higher strength and toughness when faced with external tearing forces. The PVC backing paper 1 and top backing paper 9 can be easily torn off without leaving glue residue or risking damage to the PVC film sheet 3. At the same time, the PVC material also has a certain degree of self-lubrication, making the installation and disassembly of the PVC lettering film smoother and further improving the user experience. PVC also has a certain degree of tear resistance, increasing the strength of the PVC lettering film.

[0029] In a further preferred embodiment of the present invention, the thermal film 4 is composed of a PE film coated with thermal adhesive on both sides, and the puff film 3 is coated with phosphorescent powder.

[0030] In this embodiment, PE film is renowned for its excellent physical properties and chemical stability, exhibiting good waterproof, moisture-proof, wear-resistant, and weather-resistant properties. This choice not only ensures the stability and durability of the thermal film 4 in complex environments but also provides it with strong adhesion. The flexibility of PE film also allows the thermal film 4 to easily adapt to various complex curved surfaces, ensuring the perfect presentation of the Puff lettering film in different application scenarios. By applying luminescent powder to the Puff film 3, the Puff lettering film can emit a soft glow at night or in low-light environments, bringing users a unique visual experience. This design not only enhances the aesthetics and visual appeal of the Puff lettering film but also provides unlimited possibilities for its application in areas such as nighttime signage, decoration, and safety warnings.

[0031] In summary, compared with related technologies, this device, through the ingenious combination of backing paper 1, adhesive sheet 2, puff film 3, and thermal film 4, constructs a stable and easy-to-operate puff lettering film system. The backing paper 1, as the foundation, provides necessary support and stability, ensuring the integrity of the puff film 3 during processing, transportation, and pasting. The strong adhesive force of the adhesive sheet 2 ensures that the puff film 3 adheres firmly to the backing paper 1, preventing detachment or displacement during subsequent operations. The thermal film 4 further enhances the overall stability of the puff film 3. This directional protection mechanism not only responds to temperature stimuli to achieve a tight fit but also maintains protection for the puff film 3 during hot-press bonding. It loses its adhesiveness upon heating, facilitating disassembly. This invention fully considers the performance and characteristics of different materials to achieve the best overall effect. The puff film 3 is made of a special material with excellent flexibility and wear resistance, allowing it to adhere tightly to hard surfaces and textiles, ensuring the clarity and durability of text, patterns, and other information. Simultaneously, the puff film 3 also possesses good elastic recovery capabilities, adapting to various conditions. To mitigate the stretching and deformation of the fabric, the risk of breakage due to fabric pulling is effectively reduced. The excellent physical properties and chemical stability of the PE film ensure the stability and durability of the thermal film 4, providing it with strong adhesion and allowing it to easily adapt to various complex curved surfaces. A groove 5 and a pinch tab 6 are added to the side of the thermal film 4 away from the backing paper 1, providing users with an intuitive and easily identifiable operating area, facilitating easy and comfortable gripping and removal of the thermal film 4. The introduction of double-sided adhesive 8 and top backing paper 9 further enhances the puff's texture. The structural strength of the lettering film gives it higher tear resistance when faced with external tearing forces. The waterproof membrane 7 protects the lettering film from moisture erosion and extends its service life. By precisely setting the ratio of the spacing length of the puff film 3 to its inner diameter length to 1:5, the spacing between the puff film 3 is reasonably controlled, which ensures sufficient visual impact and avoids the overall structure from becoming loose due to excessive spacing. At the same time, this layout design also improves installation efficiency, reduces material waste, and lowers production costs.
