What is hot stamping on packaging bags, and what are its applications?

Hot stamping, also known as hot printing, is a printing and decoration process that involves heating a metal printing plate, applying foil, and pressing golden text or patterns onto printed materials. With the rapid development of hot stamping foil and the packaging industry, the application of electroplated aluminum hot stamping is becoming increasingly widespread. Hot stamping features clear and beautiful patterns, vibrant colors, and wear and weather resistance.

Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will summarize the applications of hot stamping technology:

1. Ordinary gold and laser gold hot stamping. It can be used for most packaging products and its application is relatively common.

2. Positioning holographic hot stamping. Holographic laser positioning electroplated aluminum is a special process application in design, with corresponding anti-counterfeiting patterns, which can greatly improve the anti-counterfeiting ability of products and enhance product grade. This electroplated aluminum is generally domestically produced, and its price is relatively cheaper compared to imported goods, but its hot stamping performance is slightly inferior. Holographic laser positioning electroplated aluminum is greatly affected by the control of hot stamping temperature, pressure, speed, and even the type of hot stamping machine.

3. Special application of electroplated aluminum in the process. Printing after hot stamping is a new creative idea in the cigarette packaging design and printing industry. This process has high requirements for electroplated aluminum. In addition to accurate hot stamping position, smooth and bright surface, balanced and uniform pressure, no bubbles or blurring, it is also necessary to pay special attention to the fact that there should be no obvious indentations at the edges of the hot stamping pattern, and the hot stamping electroplated aluminum should have good adhesion to the printing surface, and no obvious scratches.

The hot stamping process is actually the process of heating and pressing the outer plastic film of the packaging bag. Special attention should be paid to the protection of semi-finished products. During production, various unfavorable factors that cause deformation of the packaging bag film should be minimized, which is very helpful for the smooth progress of the post-hot stamping process and the improvement of product qualification rate.

In Direct hot stamping on the UV coating surface has very high requirements for both the UV coating and the hot stamping electroplated aluminum. When applying the coating, attention should be paid to controlling the amount of coating to ensure the relative stability of the coating of the entire batch of products, and the coating layer should be thin and flat; for the electroplated aluminum used for hot stamping, it is required to be high-temperature resistant, have good adhesion, and good hot stamping compatibility with the coating (the resin type used in the coating matches the hot melt adhesive in the electroplated aluminum). In all products, the application range of this process is relatively small.

In addition, hot stamping on gold, silver ink and matte oil also has high requirements for the hot stamping surface and electroplated aluminum. If the ink particles on the hot stamping surface are too large or the surface is rough, it will directly affect the normal progress of hot stamping.
