Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum technology, specifically to a temperature-sensitive heat transfer electroplated aluminum with good coverage. Background Technology

[0002] Electroplated aluminum foil, commonly known as hot stamping foil, is made by processing a release layer, a coloring layer, vacuum metallization, and a hot stamping adhesive layer onto PET film. A specialized hot stamping machine transfers the coating from the film into text or patterns onto the object being stamped. Current electroplated aluminum foil includes ordinary electroplated aluminum foil, laser electroplated aluminum foil, and anti-counterfeiting label electroplated aluminum foil. It is mainly used for product packaging, giving it a high-end, exquisite, and personalized look, while also providing anti-counterfeiting features.

[0003] A search revealed Chinese patent application number 201520493022.6, which discloses a photochromic electroplated aluminum. This aluminum is composed of a base film, a release layer, an information layer, a reflective layer, and an adhesive layer stacked from top to bottom. It is an electroplated aluminum that changes color according to different light sources or changes in light intensity, offering improvements in decoration and anti-counterfeiting compared to existing electroplated aluminum, with easily identifiable effects. However, this patent has the following shortcomings in practical use: It lacks a waterproof layer, making it easily soaked when water droplets fall on it, affecting its performance. Furthermore, its color stability is poor; ultraviolet light causes oxidation on the surface, leading to fading and whitening after prolonged exposure to sunlight. Utility Model Content
