Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of card making, in particular to a film-coated PVC color card base. Background Art
[0002] The base color of PVC color card base is the basic color of each card, and the color is darker. The visual effect of directly printing various colored patterns and texts is poor. Before printing patterns and texts, a white layer (called printing layer) must be covered on the color card base as the background to give the card text and pattern a good visual aesthetic. The original PVC color card base printing layer production process is completed by screen printing or coating process route.
[0003] However, screen printing has low efficiency. Although coating printing has solved the efficiency problem, it still has the following defects: 1. Unstable hiding power; 2. Poor whiteness controllability; 3. Poor peeling force. Therefore, there is an urgent need for a solution that can further improve the performance of the color card base. Utility Model Content
[0004] The utility model aims to provide a film-coated PVC color card base to solve the technical problem of insufficient application performance of the color card base.
[0005] In order to solve the above technical problems, the utility model provides a film-coated PVC color card base, comprising: a card base layer and a PVC printing layer stacked in sequence; the thickness of the PVC printing layer is 0.02-0.04 mm.
[0006] Furthermore, the card base layer has a thickness of 0.4 to 0.6 mm.
[0007] Furthermore, the peel strength of the PVC printed layer is not less than 11.4 N / cm.
[0008] Furthermore, the whiteness of the red card base coating of the coated PVC color card base is not less than 96.89.
[0009] Furthermore, the whiteness of the blue card base coating of the coated PVC color card base is not less than 97.89.
[0010] The beneficial effect of the utility model is that the coated PVC color card base of the utility model abandons the original cumbersome processes of screen printing and coating printing, and forms a composite material by directly arranging a PVC printing layer on the color card base layer, which greatly improves the production efficiency of the card factory and reduces costs. At the same time, the improved structure has stable and controllable whiteness, good covering performance, high composite fastness of the printing layer, and clear ink after offset printing, which improves the product quality of the card factory. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0012] Figure 1 It is a structural schematic diagram of the film-coated PVC color card base of the utility model.
[0013] In the figure:
[0014] Card base layer 1, PVC printing layer 2. DETAILED DESCRIPTION
[0015] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0016] like Figure 1 As shown, this embodiment provides a laminated PVC color card base, comprising: a card base layer and a PVC printing layer stacked in sequence; the thickness of the PVC printing layer is 0.02-0.04 mm.
[0017] Specifically, the thickness of the existing screen printing process layer is 0.20-0.22 mm, and the thickness of the coating process printing layer is 0.005-0.01 mm. Although the thickness of the PVC printing layer in this embodiment is 0.02-0.04 mm, which is higher than the thickness of the coating process printing layer, the screen printing process layer, which is a structural layer that must be set in the existing process, is discarded, which greatly reduces the thickness of the card base.
[0018] In this embodiment, specifically, the thickness of the card base layer is 0.4-0.6 mm.
[0019] In this embodiment, specifically, the peel strength of the PVC printed layer is not less than 11.4 N / cm, the industry standard requirement is ≥6 N / cm, the peel strength of the traditional screen printing layer is 6.6-7.5 N / cm, and the test standard is: GB / T 2792-2014, 90° peeling; in this embodiment, the peel strength is greatly improved by directly bonding the PVC printed layer to the card base layer.
[0020] In this embodiment, specifically, the whiteness of the red card base coating of the coated PVC color card base is not less than 96.89.
[0021] In this embodiment, specifically, the whiteness of the blue card base coating of the coated PVC color card base is not less than 97.89.
[0022] Specifically, the hiding power and whiteness of various card bases were compared, and the performance was as follows.
[0023] Example Whiteness Red card base lamination 96.89 Blue card base lamination 97.89 Screen printed red card base 82.06 Red coated card base 79.34、88.69 Blue coated card base 93.92
[0024] It can be seen that the whiteness of the red card base and the blue card base are greatly improved under the structure of this embodiment.
[0025] In summary, this embodiment provides a laminated PVC color card base, which includes: the laminated PVC color card base abandons the original cumbersome processes of screen printing and coating printing, and forms a composite material by directly setting a PVC printing layer on the color card base layer, which greatly improves the production efficiency of the card factory and reduces costs. At the same time, the improved structure has stable and controllable whiteness, good covering performance, high composite fastness of the printing layer, and clear ink after offset printing, which improves the product quality of the card factory.
[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
