Shantou Jinlan Machinery has newly developed a single sheet of cold ironing equipment

Cold stamping technology is a printing technology that uses a UV-curing adhesive to transfer foils onto printing materials using a printing plate. It breaks the traditional bronzing process of relying on hot pressure to transfer gold foil, which not only solves the technical problems that are difficult to solve in hot foil printing, but also avoids the environmental pollution caused during the production of metal printing plates, and can also save a lot of energy. Cold press technology has the advantages of fast printing speed, short production cycle, wide application of materials, high printing precision, good anti-counterfeit effect, and compliance with environmental protection printing requirements. It is the latest scientific and technological achievements in the European and American printing industry in recent years.

In China, because of its strong visual impact, metal packaging materials can make the color of commodity packaging beautiful. It has become a packaging material that is highly recommended by businesses and is rapidly being applied to various commodity packaging. The sales of high-grade cigarette products have determined that the packaging will inevitably become the focus of the cigarette factory. The packaging of cigarettes is no longer a simple design and the production of rough old faces, have changed their bones, and use a lot of metal luster and high-luminosity aluminum foil composite Or PET coated cardboard and other materials. However, due to the non-degradability of such materials, it is easy to cause environmental pollution and inevitably bring about an environmental crisis. With the establishment of environmental protection awareness, especially in the face of the green trade barriers imposed by developed countries after the accession to the WTO and the impact of low tar and high environmental protection cigarettes on the domestic market, green environmental protection has become an irresistible trend in the development of tobacco packaging. Being phased out is a foregone conclusion.

So what kind of environmentally friendly materials are used to replace composite packaging materials?

Cold ironing technology is an ideal choice. It not only has the characteristics of all transfer gold and silver cardboard, but also meets the needs of the existing cigarette package market in China to pursue individualization. The existing cold-stencil technology is mainly applied to narrow-width flexo printing machines, but it is only suitable for printing roll-shaped substrates. Cannot be used with existing sheetfed presses. And printing adhesives are mainly used in flexo printing units. Flexographic printing units can easily produce problems such as broken lines, pastes, etc. in the printing of fine lines, small texts, large fields, and halftone patterns. difference. On-line offset printing, web flexo cold foiling In production, hot stamping foils run at the same speed as the printing cylinders, and the circumference of the printing cylinders is not always the same as the size of the product, and the gold foil foil is wasted. In addition, the stencil seam problem of holographic hot stamping foil also greatly restricts the application of the cold ironing process.

In response to these circumstances, Shantou Jinlan Machinery has recently developed a single sheet of cold ironing equipment. When the printing equipment is used to print adhesives such as UV oil, the distance between two adjacent printing materials is very compact when it is cold-stenciled, so that the utilization rate of hot foil is improved. In addition, when the holographic hot stamping foil is cold-ironed, the device-configured photoelectric eye monitoring system can monitor the position of the hologram foil in real time and transmit the signal to the servo mechanism. The servo mechanism controls the substrate speed and real-time according to the signal. The position is such that the gap position of the substrate is just aligned with the position of the hologram hot stamp foil. In this way, the surface of the substrate can avoid holographic hot stamping foil seams, greatly improving the pass rate of printed products. At the same time, the equipment can be freely applied to the processing of raw materials before printing to produce special printing effects. Or it is the realization of surface metal decoration effect after the printed matter is printed, and metal decoration effects such as fine lines, small texts, large solid ground, and halftone patterns are smoothly achieved on the substrates.

At present, the device has applied for national patents and is intended to fill the gap in the domestic technology.
