Color sealing material for edge of card base and manufacturing method thereof

Abstract

The invention relates to the field of materials, and specifically discloses a color sealing material for the edge of a card base and a manufacturing method thereof. The color sealing material is formed by a base film layer, a separation gel layer, a sealing protection layer, a colored tape layer and an adhesive layer which are in successive arrangement. The color sealing material for the edge of the card base can be transferred to the edge of the card base after heating, so the adhesive layer is directly adhered to the edge of the card base; and after the color sealing material is dried and fixed, the base film layer on the edge of the card base is torn off, so the card base with a colored edge is formed. The color sealing material provided by the invention can effectively prevent the phenomenons of layering and stripping of the cross section of the card base, can improve smoothness of the cross section of the card base and overall beauty of the card base, and has advantages like simple and convenient operation, low cost and high efficiency at the same time.

Description

technical field [0001] The invention relates to the field of materials, and specifically discloses a card base edge color sealing material and a manufacturing method thereof. Background technique [0002] At present, most of the card products in the society use PVC, PET, PETG, PC and other plastics and paper materials to make the card base. Way to make card base. The cross-section of the punched card base is the original color of the material, which is different from the color printed on the surface of the card base, which affects the overall appearance of the card base product. More importantly, the card base is made of multi-layer materials. The cross-section of the base has been exposed for a long time. Over time, the cross-section of the card base often has interlayer delamination, which seriously affects the use of card products. Especially in recent years, with the demand for high-temperature resistant card products in the market, the card base material adopts This d...
