Problems solved by technology

Metal labels are mostly made of metals or alloys such as copper, iron, zinc, aluminum, tin, nickel, etc., and most of the metal labels are hard and cannot be printed by printing machines. Most of them are colored by electroplating, and the color is relatively single.
Metal aluminum has relatively good ductility due to its low hardness. It can be made into aluminum foil for printing. Aluminum foil also has good printability and can be used for multi-color ink printing. However, due to the certain stiffness of aluminum foil, large-area labels When labeling, there will be problems such as the label is not easy to fit and easy to wrinkle, which also greatly limits the development and application of metal labels

Embodiment 1

[0014] A metal label, which includes a metal substrate and a printing layer from bottom to top, and the metal substrate includes tin foil with a thickness of 0.03mm and aluminum foil with a thickness of 0.01mm from bottom to top; the specific preparation process includes the following steps:

[0015] Take aluminum foil with a thickness of 0.01mm and tin foil with a thickness of 0.03mm for solvent-free compounding to obtain a metal substrate, then place the metal substrate on a gravure printing machine, and print white, gold, black, red and brown on the surface of the aluminum foil , cut according to actual needs to get metal labels.

Embodiment 2

[0017] A metal label, which includes a metal substrate and a printing layer from bottom to top, and the metal substrate includes lead foil with a thickness of 0.5mm and aluminum foil with a thickness of 0.01mm from bottom to top; the specific preparation process includes the following steps:

[0018] Take aluminum foil with a thickness of 0.01mm and lead foil with a thickness of 0.5mm for solvent-free compounding to obtain a metal substrate, then place the metal substrate on a screen printing machine, and print white, gold, black, red, and brown on the surface of the aluminum foil Five-color printing, cutting according to actual needs to get metal labels.

Embodiment 3

[0020] A metal label, which includes a metal substrate and a printing layer from bottom to top, and the metal substrate includes tin foil with a thickness of 0.02mm and aluminum foil with a thickness of 0.06mm from bottom to top; the specific preparation process includes the following steps:

[0021] Take an aluminum foil with a thickness of 0.06mm and a tin foil with a thickness of 0.02mm for solvent-free compounding to obtain a metal substrate, then place the metal substrate on a screen printing machine, and print five colors of white, gold, black, red and brown on the surface of the aluminum foil Printing, cutting according to actual needs to get metal labels.

Abstract

The invention discloses a metal label and a preparation method thereof. The metal label sequentially comprises a metal substrate and a printing layer from bottom to top, wherein the metal substrate sequentially comprises a first metal foil and an aluminum foil from bottom to top, and the first metal foil is a tin foil or a lead foil. The metal label is advantaged in that the metal label is ingenious in design and low in production cost, special equipment and instruments are not needed, a problem that a metal aluminum label is prone to wrinkling and edge warping is solved, meanwhile, better plasticity is achieved, application of the metal label can be further broadened, and wide market prospects are achieved.

Description

technical field [0001] The invention belongs to the field of labels, and in particular relates to a metal label and a preparation method thereof. Background technique [0002] Labels are classified according to their materials, including paper labels, plastic labels, paper-plastic materials, metal labels, etc. Most of the metal labels are made of metals or alloys such as copper, iron, zinc, aluminum, tin, nickel, etc., and most of the metal labels are hard and cannot be printed by printing machines. Most of them are colored by electroplating, and the color is relatively simple. Metal aluminum has relatively good ductility due to its low hardness. It can be made into aluminum foil for printing. Aluminum foil also has good printability and can be used for multi-color ink printing. However, due to the certain stiffness of aluminum foil, large-area labels When labeling, there will be problems such as the label is not easy to fit and easy to wrinkle, which also greatly limits th...
