Application of  roll to roll coating machine

Roll to roll coating is a technology of continuous coating on flexible substrate by physical vapor deposition. Generally speaking, roll to roll coating has two functions: one is functionality, the other is for decorative function. The so-called functionality is to use different coating methods to coat semiconductor film, metal film, insulating film, optical multilayer film on flexible substrates such as plastic film, paper, metal belt, cloth, etc., which can improve its surface hardness, mechanical strength and water resistance, and make it have conductivity, reflection and absorption, Insulation, barrier, anti-static, etc. For example for coating touch screen, capacitor, automobile film and building film (Low-E film). The so-called decorative film is the use of a variety of metal and optical film luster, color to make it more beautiful, generous, durable, expanding its life time. If metal and dielectric film are plated on the plastic surface, the plastic can have a strong metal or dielectric light layer, such as coating chrome, aluminum or dielectric film.

The common vacuum roll to roll coating machine can be divided into evaporation roll to roll coating, magnetron sputtering roll to roll coating and combined roll to roll coating according to its working principle. The evaporation roll to roll coating can be divided into resistance heating evaporation and electron beam evaporation. The magnetron sputtering roll to roll coating can be divided into DC sputtering and intermediate frequency reactive sputtering. The combined roll to roll coating can be divided into resistance evaporation and magnetron sputtering, The combination of resistance evaporation and electron beam evaporation, electron beam evaporation and magnetron sputtering, etc.

At present, roll to roll vacuum coating technology is used in various industries. In practical application, most of them are resistance heating evaporation vacuum roll to roll coating equipment. This kind of equipment is mainly used in low melting point metal materials such as aluminum plating and zinc plating. Products are widely used in packaging, decoration, printing, textile, food packing, anti-counterfeiting, cigarette, electronic industry and other fields, such as "gold and silver" box in cigarette industry, Wine label paper, food packaging paper, etc.
