The History Of Hot Stamping And Application Areas

  With the development of the national economy and printing packaging industry, people gradually demand high-grade, exquisite, environmental protection and rich personalization for packaging products. Hot stamping process in the semi-automatic hot stamping machine, automatic hot stamping machine after the use of improved production efficiency, reduce costs. Hot stamping has two main functions: one is the surface decoration, can improve the added value of the product. Second is to give the product a high anti-counterfeiting performance, such as the use of holographic positioning stamping trademark logo.

1.hot stamping development history

The hot stamping process emerged in modern times, and since 1950s, the process has gradually become popular on plastic products, which is a very important anti-counterfeiting measure.

2. Application fields

(1) ordinary gold, holographic gold hot stamping, applied to most products positioning holographic hot stamping, improve anti-counterfeiting ability, holographic laser positioning electrochemical aluminum in the design of a special process application, with the corresponding anti-counterfeiting pattern, can greatly improve the product's anti-counterfeiting ability, but also to improve the product's grade. This kind of electrochemical aluminum is generally domestic production, compared with foreign imports, the price is cheaper, but the hot stamping processing performance is slightly worse. Holographic laser positioning electrochemical aluminum on the hot stamping processing temperature, hot stamping processing pressure and speed control, and even hot stamping processing machine type have a great deal to do with.

(2) first after the hot stamping, the process of high requirements for the electrochemical aluminum, in addition to the accurate location of the hot stamping processing, smooth and bright appearance, pressure balance, uniform, no blistering, no paste plate requirements, but also pay special attention to the edge of the hot stamping processing pattern can not have obvious indentation, hot stamping processing electrochemical aluminum in the hot stamping surface to have good adhesion, as well as no obvious scuffing and scratching and other phenomena.

(3) in the UV varnish surface directly gold plating, UV varnish and hot stamping aluminum requirements are high, varnish coating, to pay attention to control the size of the oil, try to ensure that the whole batch of products varnish coating relative stability, and oil layer to thin, flat; for hot stamping processing of aluminum, require high temperature resistance, good adhesion, and varnish has a good hot stamping processing suitability in all products, the application of this process is small. in addition, the aluminum in gold, silver ink and matte oil hot stamping processing also on the hot stamping processing appearance and hot stamping processing of aluminum has high requirements, if the hot stamping processing appearance of ink particles larger or rough surface, will directly affect the normal hot stamping processing.

  We all know that the hot stamping process is actually a paper heat and pressure process. For white card, glass card, pay special attention to the maintenance of semi-finished products, the production process to minimize the paper deformation of various favorable factors, so that the smooth conduct of the post-stamping processing process, the product qualification rate is very helpful. The application of hot stamping processing process will encounter the problem of how to improve the efficiency of production, especially for a large number of products is very necessary to improve the process.

  Hot stamping in lipstick tube, serum, mascara, shampoo bottles and other cosmetic packaging products are more widely used, such as some daily chemical packaging products lotion pump’s  circle, airless bottles, perfume pump, etc..
