Description
Technical Field
[0001] This utility model belongs to the field of cigarette packaging technology, specifically relating to a flavored, environmentally friendly laser packaging paper. Background Technology
[0002] Laser paper is widely popular in the market due to its unique gloss and visual effects. However, traditional laser paper printing often uses solvent-based inks, which poses environmental pollution problems.
[0003] Currently, in order to improve environmental friendliness, water-based inks are being used instead of solvent-based inks. Although this reduces VOC emissions, it also reduces functionality and sensory experience.
[0004] Therefore, how to balance these factors has become a key problem that urgently needs to be solved in this field. Utility Model Content
[0005] This invention provides a scented, environmentally friendly laser packaging paper. It uses water-based, odorless, amine-free ink for die-cutting printing on ordinary laser paper and introduces microcapsule technology. Under the premise of environmental protection, it allows customers to have a multi-sensory experience including touch, smell, and sight when using it.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a scented, environmentally friendly holographic packaging paper, comprising:
[0007] Laser-etched paper layer;
[0008] A perforated printing layer is arranged on the upper surface of the laser base paper layer;
[0009] Microcapsule ink layer, wherein the microcapsule ink layer is disposed on the upper surface of the stencil printing layer;
[0010] A photochromic ink layer, which covers the upper part of the microcapsule ink layer;
[0011] The laser base paper layer is a water-based transfer full-page laser paper with a five-layer composite structure.
[0012] Preferably, the perforated printing layer uses water-based, odorless, amine-free ink.
[0013] Preferably, the microcapsule ink layer is a sustained-release microcapsule, the shell of the sustained-release microcapsule is a nanoscale polymer, and the core material of the sustained-release microcapsule is a micron-sized fragrance particle.
[0014] Preferably, the microcapsule ink layer covers a localized area on the upper surface of the stencil printing layer.
[0015] Preferably, the laser base paper layer consists of, from bottom to top, a transfer film, a molded laser layer, a water-based transfer coating layer, an ultra-thin aluminum plating layer, a water-based adhesive layer, and a base paper layer;
[0016] The water-based transfer coating layer is a water-based polyurethane coating, and the thickness of the ultra-thin aluminum plating layer is 20-50 nanometers.
[0017] Preferably, the transfer film needs to be peeled off before the laser base paper layer is cut out.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] (1) The embossed laser layer in this utility model provides a strong visual impact, the hollow printing layer also increases the sense of layering and artistry of the packaging, the microcapsule ink layer emits a unique fragrance, creating a unique olfactory memory, and the light-changing effect of the light-changing ink layer presents a novel visual transformation experience. The multi-sensory interaction allows consumers to see the gorgeous visual effect of the laser packaging paper, smell the pleasant fragrance, and touch it, presenting a sensory feast, enhancing product memory points, and improving customer experience.
[0020] (2) The aluminum plating process of this utility model uses ultra-thin aluminum foil with low aluminum content, and all inks are water-based environmentally friendly coatings with low VOC emissions. At the same time, the introduction of microcapsule technology and its biodegradable polymer wall material further reflects the pursuit of green concept in the entire life cycle of packaging paper.
[0021] (3) The combination of multiple anti-counterfeiting technologies, including its unique hollow design, distinctive fragrance in microcapsules, and water-based coatings, makes this fragrance-enhanced environmentally friendly laser packaging paper unique. Its multi-stage and multi-field anti-counterfeiting measures are unreplicable. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1:
[0028] like Figure 1 As shown, this embodiment provides a scented, environmentally friendly laser packaging paper, comprising a laser base paper layer 1, a perforated printing layer 2 disposed on the upper surface of the laser base paper layer 1, a microcapsule ink layer 3 disposed on the upper surface of the perforated printing layer 2, and a photochromic ink layer 4 covering the upper part of the microcapsule ink layer 3. The perforated printing layer 2 uses water-based, odor-free, amine-free ink. The microcapsule ink layer 3 consists of slow-release microcapsules. The shell of the slow-release microcapsules is a biodegradable nanoscale polymer material, and the core material of the slow-release microcapsules is micron-sized fragrance particles. The micron-sized fragrance particles are slowly released through the porous nanoscale polymer shell. The slow-release microcapsules are existing technology and are directly purchased finished products; therefore, detailed descriptions of their structure and principles are not provided here.
[0029] Among them, the microcapsule ink layer 3 covers a local area on the surface of the stencil printing layer 2, which can save the amount of microcapsule ink while emitting fragrance.
[0030] Example 2:
[0031] Based on Example 1, in order to improve the sensory experience, the laser base paper layer 1 is arranged as a water-based transfer full-page laser paper with a five-layer composite structure.
[0032] Specifically, the laser base paper layer 1 consists of, from bottom to top, a transfer film 8, a molded laser layer 7, a water-based transfer coating layer 6, an ultra-thin aluminum plating layer 5, a water-based adhesive layer 10, and a base paper layer 9.
[0033] Among them, the water-based transfer coating layer 6 is a water-based polyurethane coating, and the transfer film 8 needs to be peeled off before the laser base paper layer 1 is cut out.
[0034] To reduce VOC emissions, the thickness of the ultra-thin aluminum-plated layer 5 is arranged to be 20-50 nanometers, thus reducing the aluminum content.
[0035] Working principle:
[0036] A laser-etched layer 7 is formed on the surface of the transfer film 8 by embossing a laser effect. Then, a layer of water-based polyurethane coating, namely the water-based transfer coating layer 6, is applied. Next, an ultra-thin aluminum layer 5 with a thickness of 20-50 nanometers is deposited on the surface of the water-based transfer coating layer 6. Then, the transfer film 8 is laminated to the base paper using water-based adhesive. Then, the transfer film 8 is peeled off to form a water-based full-page laser paper. Next, water-based odorless and amine-free ink is used to cut out and print graphics on the surface of the laser paper, and microcapsule ink is printed in some areas. Finally, a layer of photochromic ink is covered on the microcapsule ink printing area for protection.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
