Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of packaging material, more particularly to a high-precision pen surface set position hot stamping film. BACKGROUND

[0002] The hot stamping film is a technology that combines laser holographic aluminum film with hot stamping technology to form colorful laser holographic identification and three-dimensional pattern anti-fake identification on the surface of printed matter. With the increasing demand for product appearance and brand anti-fake function in the consumer market, printing technology and anti-fake technology are constantly innovating and progressing. For writing tools such as fountain pens and ballpoint pens, the pen surface needs to have both laser holographic patterns and printed patterns, and the two need to be aligned or set to form a complete pattern. Since the pen surface is curved, traditional hot stamping + offset printing processes cannot be used. Currently, the two-step hot stamping process is commonly used for pen surface pattern processing. The first step is to stack the base film, the mold pressing layer, the aluminum plating layer, the support layer, and the adhesive layer in order, and then gradually transfer these layers to the surface of the object to be hot stamped by heat pressing. Finally, the base film is peeled off. The second step is to hot stamp the new base film, release layer, printing layer, support layer, and adhesive layer in a similar manner. The above process has a complex process flow and takes a long time. In particular, in the second step, the precise set position between the layers is required to be very high, otherwise it will directly affect the final hot stamping effect and aesthetics. In addition, the support layer and the adhesive layer are required for the two hot stamping processes, which further increases the material cost and the operation difficulty. SUMMARY

[0003] The utility model aims at providing a high-precision pen surface set position hot stamping film, which can hot stamp the mold pressing layer, the aluminum plating layer, and the printing layer to the pen surface only once, simplifying the process, improving the efficiency, and saving the material cost.

[0004] The utility model is implemented by the following technical solutions:

[0005] That is, a high-precision pen surface set position hot stamping film, comprising a base film, characterized in that the surface of the base film is sequentially provided from bottom to top with a release layer, a mold pressing holographic layer, an aluminum plating layer, a transparent dry adhesive layer, a high-temperature-resistant printing layer, a support layer, and an adhesive layer. The aluminum plating layer is provided with a plurality of hollow windows. The transparent dry adhesive layer is fully coated on the aluminum plating layer. The high-temperature-resistant printing layer is partially or entirely distributed in the hollow windows.

[0006] Further, the base film of the utility model is a BOPP film or a PET film, with a thickness of 15-25 microns, good heat resistance, and toughness

[0007] Further, the aluminum plating layer of the utility model has a thickness of 350-500 Å. The aluminum plating layer is attached to the surface of the mold pressing holographic layer by vacuum aluminum plating technology to ensure good gloss and reflection effect.

[0008] Further, the support layer is PET layer or PVC layer, and the thickness is between 20-30 microns, and the support layer is high heat-resistant material.

[0009] The molded holographic layer comprises a molded coating layer and a holographic pattern, the molded coating layer is a transparent polymer coating layer, and is used for pressing the holographic pattern or other microstructures, and the holographic pattern can be pressed by a pressing equipment at 160-180 DEG C, and the vehicle speed is 40-60 m / min, so that the accuracy of the pattern is ensured.

[0010] The dry glue layer is fully coated on the aluminum plating layer, and the dry glue process has the advantages of high composite firmness and good accuracy, and displacement is not prone to occur, so that the subsequent hot stamping process is more accurate, the coating amount of the glue should be controlled to be 5-10 g / m2 during the compounding, the drying temperature is 80-110 DEG C, so that the glue is fully cured and the subsequent hot stamping step is not affected.

[0011] The high-temperature-resistant printing layer is printed on the dry glue layer by using high-precision flexographic printing technology, and the printing content can be text, pattern, logo or the like, the high-temperature-resistant printing layer uses ink resistant to high-temperature environment during printing, and can maintain stability at a temperature of 160-180 DEG C and will not discolor or fail.

[0012] The dry glue layer is a transparent layer and does not affect the display of the printing layer.

[0013] The high-temperature-resistant printing layer, the molded holographic layer and the aluminum plating layer are first compounded together by using dry compound glue, and then hot stamping is performed, so that the complex step of secondary alignment is avoided.

[0014] The selection of the support layer and the back glue layer directly relates to the adhesion and firmness of the hot stamping pattern on the pen body.

[0015] The back glue layer is a strong adhesive, can be rapidly cured at high temperature and firmly combined with the surface of the pen body, the coating amount of the back glue layer is controlled to be 20-30 microns thick, the hot stamping temperature is 160-180 DEG C, and the hot stamping time is 5-10 seconds, so that the pattern is tightly attached to the surface of the pen body.

[0016] During hot stamping, the composite printing layer, the molded holographic layer and the film of the aluminum plating layer are placed in a hot stamping equipment, the support layer and the back glue layer are hot stamped on the pen body by heating and pressure, the working temperature of the hot stamping equipment is 160-180 DEG C, and the pressure is 2-4 kg / cm2, so that each layer can be uniformly heated and firmly transferred to the surface of the pen body.

[0017] The utility model has the advantages that:

[0018] 1) Process simplification: traditional pen body hot stamping requires two different material hot stamping processes, using the hot stamping film of the utility model, reducing one hot stamping step, significantly improving the production efficiency;

[0019] 2) Holographic pattern and printed pattern accurate location, avoid the deviation that two hot stamping in traditional process can produce, thereby greatly improve the quality of pattern, especially for complex, multi-level pattern design, the effect is more stable and outstanding;

[0020] 3) Material saving, the support layer and the back adhesive layer of the traditional process are used twice, the support layer and the back adhesive layer of the utility model only need to be used once, save the material, reduce the production cost, improve the economic benefit;

[0021] 4) Wide application range, the process of the utility model can be applied to various types of pens and other similar cylindrical or curved surface articles. BRIEF DESCRIPTION OF DRAWINGS
