Description

TECHNICAL FIELD

[0001] The utility model relates to an advertisement printing material, especially to a high-definition cold laminating film with synthetic paper base structure. BACKGROUND

[0002] The cold laminating film is usually pasted on the spray painting material, and the spray painting material is protected by the cold laminating film after printing, so that the printed spray painting material is lightfast, heat-resistant and water-resistant, and the service life is prolonged, and the cold laminating film is pasted on the required position for display. The cold laminating film for protecting indoor / outdoor spray painting advertisement consumables in the prior art is usually obtained by pasting transparent PVC or transparent PP with pressure-sensitive adhesive and release paper.

[0003] 1. Since the paper base is rough, even if a film is sprayed on the surface of the paper base and a layer of silicon oil is coated, the roughness cannot be satisfied, the adhesive surface is affected by the microscopic unevenness of the release paper, and the pattern after lamination is prone to uneven line problems such as snowflake points, which affects the visual clarity of the pattern;

[0004] 2. The release paper with the paper base does not meet the requirements of national ecological forestry protection;

[0005] 3. The most commonly used release paper is a spraying paper obtained by spraying a layer of plastic particles on the surface of paper, which is a paper-plastic hybrid and is not convenient for recycling and reuse;

[0006] 4. The release paper is greatly affected by environmental temperature and humidity, is prone to curling, reverse warping, and tearing, and often needs to be set according to the weather temperature and humidity, which has high requirements on workers and processes in the application to cold laminating film production and processing.

[0007] Therefore, it is necessary to optimize the structure of the cold laminating film to overcome the above-mentioned defects. CONTENT OF THE UTILITY MODEL

[0008] The utility model aims to provide a high-definition cold laminating film with synthetic paper base structure to improve the cold laminating effect.

[0009] The utility model adopts the technical scheme that:

[0010] A high-definition cold laminating film with synthetic paper base structure comprises:

[0011] A base bearing layer body is made of synthetic paper;

[0012] The anti-sticking release layer is made of an anti-sticking material and is arranged on the base bearing layer to isolate the base bearing layer and make the base bearing layer have anti-sticking performance.

[0013] The transparent protective layer is made of a transparent material.

[0014] The switching adhesive layer is made of an adhesive material and is arranged on the transparent protective layer and is combined with the anti-sticking release layer, so that the transparent protective layer can be adhered to or separated from the base bearing layer.

[0015] Specifically, the base bearing layer is made of any one of PP synthetic paper, pearl film, polypropylene and polyethylene terephthalate.

[0016] In an embodiment of the utility model, the transparent protective layer is made of polyvinyl chloride or polypropylene.

[0017] In an embodiment of the utility model, the anti-sticking release layer is coated on the surface of the base bearing layer by using ultraviolet curing silicone oil release agent.

[0018] In an embodiment of the utility model, the switching adhesive layer is formed between the transparent protective layer and the anti-sticking release layer by using an adhesive.

[0019] In an embodiment of the utility model, the adhesive is made of water-based adhesive.

[0020] The utility model discloses the advantages are:

[0021] 1. High apparent flatness, which makes the glue surface on the base bearing layer more apparent and flat than the conventional release paper, making the cold mounting film prepared therefrom have higher clarity and transparency when mounting, and being suitable for high-end cold mounting applications.

[0022] 2. The polypropylene synthetic paper release film is a plastic material that is not easily affected by temperature and humidity, and when processing as a cold mounting film base layer, there is no need to set the humidity ratio according to the weather temperature and humidity, and the process requirements are lower, and the finished product authenticity rate is higher.

[0023] 3. The polypropylene synthetic paper has a bidirectional stretching function and is not easy to tear during processing, and compared with the easily torn release paper, it is easier to achieve a higher coating speed, thereby improving production efficiency.

[0024] 4. Compared with the same thickness of paper-plastic hybrid release paper, the polypropylene synthetic paper release film has lower cost, and the torn polypropylene synthetic paper and waste can be recycled, and forestry resources are also saved. BRIEF DESCRIPTION OF DRAWINGS
