Hot Stamping Technology of Anodized Aluminum Bottles
Anodized aluminum hot stamping is a very important post-press processing technology in packaging and printing, mainly hot stamping patterns, words and lines to highlight the name and trademark of the product. Ang brand, beautifying products, thereby improving the grade of packaging products.
Anodized aluminum hot stamping is also often used for post-press processing of hardcover book covers, greeting cards, calendars and other products. The peeling layer is melted, and the hot stamping process of the anodized aluminum is as follows: the anodized aluminum is heated by the hot stamping plate. Then the adhesive layer is also melted, the adhesive layer is bonded to the substrate during embossing, the colored layer is separated from the polyester base layer, and the aluminized layer and the colored layer remain on the substrate. And can also play the role of anti-counterfeiting. Hot stamping anodized aluminum on the package can not only beautify the product and improve the quality of the product. But in practical application, one of the purposes of increasing the hot stamping process is to improve the product grade. Only reasonable use can achieve twice the result with half the effort. On the contrary, it will not only fail to reflect the advantages of the product, but also cause waste. The matching of the color of the hot-stamped text or pattern with the printing color and the influence of the hot-stamping post-processing on the hot-stamping. The hot stamping area should be fully considered. This depends on the overprinting accuracy of the product. For hot stamping on a large area, the hot stamping part and the splicing of the printed pattern should also be considered. Generally set to 0.2-0.5mm, of course, the hot stamping suitability of anodized aluminum itself must be considered. Do not directly hot stamp the pattern, consider the overall effect of hot stamping and the cost of hot stamping. For example, some products tend to only hot stamp the outline and text of the pattern. In order to achieve the effect of lining the surface with dots; for the printing design of some aluminized paper cigarette packs, the hot stamping can be replaced by printing transparent yellow and then embossing, thereby reducing the cost. There are single-color printing and multi-color printing; embossing and UV glazing should be carried out after hot stamping. Generally, hot stamping products must be printed before hot stamping. Lamination, re-printing, die-cutting, gluing and other processing.
