Description

Technical Field

[0001] The utility model relates to the technical field of transfer films, in particular to a paper cold-foil transfer film. Background Art

[0002] Cold foil transfer film is a special film material used to achieve hot stamping effects on printed matter or other material surfaces without the need for traditional hot pressing technology. It is mainly composed of one or more functional layers, including an adhesive layer and a decorative layer (such as a metal layer, a color layer or a holographic layer, etc.). The working principle of cold foil transfer film is to first print a layer of special adhesive on the printed matter, then place the cold foil transfer film on the printed matter, and apply pressure (usually using the pressure roller of a printing press) to combine the decorative layer on the transfer film with the adhesive layer. Finally, peel off the excess transfer film from the printed matter, leaving only the desired decorative layer to form a hot stamping effect.

[0003] For example, in the patent document with announcement number CN206406545U, a cold stamping transfer film for paper is disclosed, including a PET base film, on which a release layer, a wear-resistant layer, a color layer and an aluminum-plated layer are coated in sequence; although this cold stamping transfer film has its unique advantages in paper hot stamping applications, it has certain limitations in terms of moisture-proof performance. In a humid environment, water molecules will gradually penetrate into the interior of the film through the tiny pores or interface gaps of the film. When the hot and humid air penetrates into the cold stamping transfer film, the inner layer of the film will soften. The softened film material will lose its original elasticity and supporting force and will not be able to effectively resist external pressure. In actual applications, this deformation will cause distortion, blurring or displacement of the hot stamping pattern. In view of this, a paper cold stamping transfer film is designed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a paper cold-foam transfer film, which can effectively prevent the penetration of water molecules and keep the inside of the film dry, thereby avoiding the problem of softening of the inner layer of the film due to moisture.

[0005] In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: a paper cold stamping transfer film, comprising a base layer, the base layer comprising a base film layer, the bottom of the base film layer is connected to an antistatic layer, the bottom of the antistatic layer is connected to a waterproof layer, and the bottom of the waterproof layer is connected to a wear-resistant layer.

[0006] Furthermore, the base film layer is one of a PET film, a PVC film or a PI film.

[0007] Furthermore, the base film layer has a thickness of 15 to 45 μm.

[0008] Furthermore, the waterproof layer is a PVC coating.

[0009] Furthermore, the antistatic layers are arranged at equal intervals.

[0010] Furthermore, the antistatic layer is arranged along the width direction of the base layer.

[0011] Furthermore, the wear-resistant layer is a silicon-modified acrylic resin layer.

[0012] Furthermore, a release layer, an adhesive layer, a decorative layer and a protective layer are sequentially arranged on the top of the base layer.

[0013] Furthermore, the decorative layer is one of a metal layer, a color layer or a holographic layer.

[0014] By means of the above technical solution, the utility model provides a paper cold stamping transfer film, which has at least the following beneficial effects:

[0015] 1. The moisture-proof performance of the cold iron transfer film is improved by setting a waterproof layer. In a humid environment, it can effectively prevent the penetration of water molecules and keep the inside of the film dry, thereby avoiding the softening problem of the inner layer of the film caused by moisture, and can maintain stable physical and chemical properties, extending the service life.

[0016] 2. The wear-resistant layer can enhance the wear resistance of the cold-ironing transfer film. During handling and transportation, it can effectively resist external friction and scratches, and protect the internal antistatic layer and waterproof layer from damage. It also enables the cold-ironing transfer film to maintain good appearance and performance during multiple uses and repeated operations.

[0017] 3. The antistatic layer can reduce or eliminate the generation and accumulation of static electricity. Static electricity will have an adverse effect on the hot stamping effect of the cold transfer film, such as causing pattern distortion or offset. The addition of the antistatic layer ensures the accuracy and stability of the hot stamping process. By reducing static electricity, the antistatic layer also reduces the risk of dust adsorption and contamination caused by static electricity, maintaining the cleanliness of the film surface and the quality of the hot stamping effect.

[0023] 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.

[0024] See also Figure 1 to Figure 3 A paper cold stamping transfer film comprises a base layer 1, wherein the base layer 1 comprises a base film layer 101, an antistatic layer 102 is connected to the bottom of the base film layer 101, a waterproof layer 103 is connected to the bottom of the antistatic layer 102, and a wear-resistant layer 104 is connected to the bottom of the waterproof layer 103.

[0025] By setting the waterproof layer 103, the moisture-proof performance of the cold iron transfer film is improved. In a humid environment, it can effectively prevent the penetration of water molecules and keep the inside of the film dry, thereby avoiding the problem of softening of the inner layer of the film due to moisture, and can maintain stable physical and chemical properties, thereby extending the service life.

[0026] The antistatic layer 102 can reduce or eliminate the generation and accumulation of static electricity, which can have an adverse effect on the hot stamping effect of the cold stamping transfer film, such as causing pattern distortion or offset. The addition of the antistatic layer 102 ensures the accuracy and stability of the hot stamping process. By reducing static electricity, the antistatic layer 102 also reduces the risk of dust adsorption and contamination caused by static electricity, maintaining the cleanliness of the film surface and the quality of the hot stamping effect.

[0027] The wear-resistant layer 104 can enhance the wear resistance of the cold stamping transfer film, effectively resist external friction and scratches during handling and transportation, and protect the internal antistatic layer 102 and waterproof layer 103 from damage. In addition, the cold stamping transfer film can maintain good appearance and performance during multiple uses and repeated operations.

[0028] The base film layer 101 is one of PET film, PVC film or PI film.

[0029] PET film has excellent transparency, which enables the pattern and color to be clearly and accurately transferred to the target paper during the hot stamping process; PET film has excellent tensile strength and impact strength, and can resist various mechanical stresses during printing and hot stamping, ensuring the stability and durability of the film; PET film can maintain stable performance in a wide temperature range and is suitable for various environmental conditions.

[0030] PVC film is a relatively low-cost base film material, suitable for large-scale production and application; PVC film is easy to process and install, and can meet the packaging needs of various irregular shapes; PVC film has good transparency and glossiness, which can improve the appearance quality of the product.

[0031] The decomposition temperature of PI film is generally over 500°C, which makes it suitable for applications in high temperature environments. It has extremely high tensile strength and elastic modulus and can resist various mechanical stresses. PI film is corrosion-resistant and hydrolysis-resistant and can maintain stable performance in harsh chemical environments.

[0032] The thickness of the base film layer 101 is 15 to 45 μm. The base film layer 101 within this thickness range has sufficient flexibility and strength to ensure that it can adapt to the slight undulations on the paper surface during the hot stamping process, and can maintain sufficient mechanical strength to prevent damage or deformation during handling and transportation.

[0033] The antistatic layer 102 is arranged at equal intervals. The antistatic layer 102 is arranged along the width direction of the base layer 1. By arranging the antistatic layer 102 at equal intervals, it is ensured that there is uniform static dissipation capability in the width direction of the entire base layer 1, preventing static electricity from accumulating in a certain area, thereby improving the overall antistatic effect. Compared with the full coverage setting, the antistatic layer 102 is arranged at equal intervals, which can significantly reduce the amount of antistatic material used, reduce production costs, and help reduce resource consumption, which meets the requirements of environmental protection and sustainable development.

[0034] The waterproof layer 103 is a PVC coating. The PVC coating has excellent waterproof properties, can effectively prevent moisture from penetrating into the interior of the paper cold foil transfer film, protect the internal antistatic layer 102 from moisture erosion, and ensure the stability and durability of the entire film structure. The PVC coating has good weather resistance, can resist the damage to the film structure caused by environmental factors such as ultraviolet rays, oxidation, high temperature and low temperature, and ensure that the paper cold foil transfer film can maintain stable performance in various harsh environments.

[0035] The wear-resistant layer 104 is a silicon-modified acrylic resin layer. The silicon-modified acrylic resin layer has excellent wear resistance and can effectively resist friction and wear that may occur during printing, processing, transportation, etc., thereby extending the service life of the paper cold foil transfer film.

[0036] The top of the base layer 1 is provided with a release layer 2, an adhesive layer 3, a decorative layer 4 and a protective layer 5 in sequence. The release layer 2 ensures that the decorative layer 4 can be smoothly peeled off from the base layer 1 and transferred to the paper during the transfer process; the adhesive layer 3 is mainly used to firmly adhere the decorative layer 4 to the target paper, and the adhesive layer 3 provides sufficient adhesion to prevent the decorative layer 4 from falling off or wrinkling during use; the decorative layer 4 is the core part of the cold stamping transfer film, and the decorative layer 4 contains the pattern, color or metal effect to be transferred to the target material. The decorative layer 4 can be a metal foil (such as aluminum foil, copper foil, etc.), color ink or other coatings with special effects; the protective layer 5 is used to protect the decorative layer 4 from damage or pollution, and the protective layer 5 is a transparent plastic film.

[0037] The decorative layer 4 is one of a metal layer, a color layer or a holographic layer. The metal layer gives the product a noble and elegant texture and glossiness, making the product look more upscale and refined. The metal layer is used in high-end packaging, gift boxes, book covers and other occasions to enhance the overall value of the product. The metal layer has excellent reflectivity and glossiness, and can produce a strong visual impact. At the same time, the metal layer also has certain wear resistance and corrosion resistance, and can protect the product surface from scratches and pollution.

[0038] The color layer provides a variety of appearance options for the product through rich color and pattern design. The color layer can be customized according to the needs of the product and the preferences of consumers to achieve a personalized decorative effect. The color layer has bright and rich colors and delicate pattern expression capabilities, which can show the characteristics and style of the product. At the same time, the color layer also has a certain covering power and durability, which can maintain the durability and stability of the product appearance.

[0039] The holographic layer provides unique visual effects and anti-counterfeiting functions for the product by using holographic technology. The holographic layer can produce three-dimensional and dynamic image effects, making the product look more vivid and interesting. At the same time, the holographic layer also has certain anti-counterfeiting properties, which can effectively prevent the counterfeiting of the product. The holographic layer has a high degree of three-dimensionality and dynamics, which can attract the attention of consumers and enhance the attractiveness of the product. In addition, the holographic layer also has certain anti-fouling and wear resistance, which can keep the appearance of the product clean and beautiful. The selection of these different decorative layers 4 can meet the needs of different products and the preferences of consumers, and enhance the overall value and attractiveness of the product.
