Description

A type of thermal paper with plastic substrate Technical Field

[0001] This utility model relates to the field of thermal paper technology, and in particular to a thermal paper with a plastic substrate. Background Technology

[0002] Thermal paper, also known as thermal fax paper, thermal recording paper, and thermal copy paper, is called thermal copy paper in Taiwan. It is a processed paper, manufactured by coating a layer of "thermal coating" (thermal color-changing layer) onto high-quality base paper. Applications of thermal paper include: serving as a communication medium for text and graphics in fax machines; as recording material in medical and measurement systems, such as electrocardiogram sheets and thermal instrument recording paper; printing paper for internet terminals; and in commercial activities, used to create trademarks, POS (Point of Sale) labels, etc.

[0003] A search of Chinese patent publication number CN204774148U reveals a type of thermal paper.

[0004] The above technical solution includes a thermal coating, a coated base paper, and a resin layer. The thermal coating is disposed on the top layer of the coated base paper, and the resin layer is disposed on the bottom layer of the coated base paper. The resin layer is a PP resin layer, a PE resin layer, a PET resin layer, or a PVA resin layer, and the bottom surface of the resin layer is coated with self-adhesive. In the above thermal paper, the bottom surface of the coated base paper has a resin layer. During the process of making thermal labels using this thermal paper, when applying glue to the thermal paper, self-adhesive can be applied to the resin layer. Since the resin layer is a PP resin layer or a PE resin layer, under the action of this resin layer, it can effectively prevent glue, solvents, etc. from penetrating through the coated base paper and damaging the thermal coating, which not only avoids material waste but also improves product quality.

[0005] However, in the above solution, the thermal layer is placed on the surface. External friction, solvents, and humidity will affect the coating, causing it to darken and obscure the printed image. This technical solution is simple, lacks anti-counterfeiting features, and is easily counterfeited.

[0006] Therefore, we propose a type of thermal paper with a plastic substrate. Summary of the Invention

[0007] The present invention aims to solve the technical problems existing in the prior art and provide a plastic substrate thermal paper.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a plastic substrate thermal paper, comprising a first substrate, characterized in that: a first information coating is disposed on the top of the first substrate, a waterproof layer is disposed on the top of the first information coating, and a wear-resistant layer is disposed on the top of the waterproof layer.

[0009] Preferably, the first substrate is a plastic mixture of polyurethane and color masterbatch, and the first information coating is a thermosensitive material.

[0010] Preferably, the waterproof layer and the wear-resistant layer are made of polyurethane.

[0011] Preferably, an antistatic layer is disposed below the first substrate, and a second substrate is disposed below the antistatic layer.

[0012] Preferably, the second substrate is provided with a second information coating, and the second information coating has reserved a blank area for marking.

[0013] This utility model provides a plastic substrate thermal paper, which has the following improvements and advantages compared with the prior art:

[0014] (1) This utility model adopts a waterproof layer and a wear-resistant layer on the surface, with a first information coating layer disposed on the first substrate, a waterproof layer disposed on the first information coating layer, and a wear-resistant layer disposed on the waterproof layer layer. The first substrate is a plastic mixture of polyurethane and color masterbatch, the first information coating layer is a thermosensitive material, and the waterproof layer and wear-resistant layer are made of polyurethane. By using a plastic mixture of polyurethane, the thermosensitive paper of this application has a high gloss, a smooth surface, and excellent dimensional stability. The waterproof layer has excellent water (wet) resistance, and the wear-resistant layer makes the surface wear-resistant and reduces coating exposure caused by friction.

[0015] (2) This utility model adopts a reserved marking blank area in the second information coating, an antistatic layer is set below the first substrate, a second substrate is set below the antistatic layer, a second information coating is set on the second substrate, and a marking blank area is reserved in the second information coating. By setting the antistatic layer, this thermal paper has excellent antistatic properties. The marking blank area is reserved in the second information coating, which can be displayed under strong light, making anti-counterfeiting identification simple. Attached Figure Description
