Hot stamping is a kind of decoration technology widely used in the printing process, usually used in some relief hot foil packing box craft, hot stamping and embossing technology is the traditional post-press processing technology, the combination of the two composite technology three-dimensional Hot stamping makes the packaging of goods appear high-end, exquisite, magnificent and full of personality. This article is shared by relief hot foil packing box seller HC packaging related knowledge of relief hot foil process, welcome to read.

Relief hot foil

Hot stamping is to use a certain pressure and temperature to use the template installed on the hot stamping machine to press the printed matter and the hot stamping plate together in a short time, and transfer the metal foil or color pigment foil to the substrate according to the graphic requirements of the hot stamping template. The processing technology of the surface of hot material. Because hot stamping is mainly gold and silver, it is often called hot stamping.

Relief hot foil process is to increase the printing of labels, trademarks, cigarette packs, and wine packaging. Hot stamping and embossing technology are traditional post-press processing technologies. The composite technology of relief hot foil process makes the packaging of goods look high-end and exquisite. Regal and full of character. Three-dimensional hot stamping is a compound technology, which combines the characteristics of hot stamping and embossing technology. Three-dimensional hot stamping itself has no pattern, but the pattern of hot stamping and embossing is made into a female intaglio with upper and lower matching by etching or engraving And positive mold relief, in order to realize the simultaneous production and processing process of hot stamping and embossing embossing technology, the resulting process effect is a three-dimensional pattern in relief shape.

From the hot stamping method, it can be divided into hot stamping technology and cold stamping technology. Hot stamping technology is the hot stamping process mentioned above that requires a certain temperature and pressure to complete the transfer of electrochemical aluminum foil. Cold stamping technology is a process of transferring anodized aluminum foil to the surface of packaging printed matter under a certain pressure by coating UV adhesive on the part of the printed matter that needs to be hot stamped. These two methods have their own characteristics and meet the requirements of different products.

Relief hot foil process

Relief hot foil process is a composite technology combining bronzing technology and concave-convex embossing technology. It uses corrosion or engraving technology to make bronzing and embossed graphics and texts into a female intaglio and male relief that match up and down to achieve Hot stamping and concave-convex embossing technology complete the process at one time. This process completes bronzing and embossing at the same time, reduces the waste products caused by processing procedures and inaccurate registration, and improves productivity and product quality.

Since the relief hot foil process is a combination of hot stamping and embossing technology, the product formed is a relief-like three-dimensional pattern, which cannot be printed on it, so the process of printing first and then hot stamping must be used. High-precision and high-quality requirements are not suitable for cold stamping technology, but more suitable for hot stamping technology. Relief hot foil process and characteristics relief hot foil process technology is very different from ordinary bronzing. In addition to forming relief-like three-dimensional patterns, it is different in plate making, temperature control and pressure control.

Process requirements for relief hot foil process

Anodized aluminum foil is generally composed of 4 to 5 layers of different materials, such as: base film layer (polyester film), peeling layer, colored layer (silver anodized aluminum has no colored layer), aluminized layer, and adhesive layer.

The main role of each layer

①The basement membrane layer mainly plays the role of supporting other layers.

②The role of the peeling layer is to separate the anodized aluminum foil layer from the base layer, which determines the transferability of the anodized aluminum layer.

③ The main function of the coloring layer is to display the color of the anodized aluminum and protect the bottom layer. Common colors are: gold, silver, brown red, light blue, black, red, green, etc., of which gold and silver are the two most commonly used.

④ The role of the aluminum coating is to present a metallic luster.

⑤ The role of the adhesive layer is to bond the hot stamping material. The adhesive materials that make up the adhesive layer are different, and their adhesive properties are also different. In order to adapt to the different surface properties of different hot stamping materials, anodized aluminum will use different adhesive layers, thus forming different types of anodized aluminum.
