2, Color fastness: string lock and tags are directly attached to the clothing, so the color fastness requirements are strong. Seal tag color fastness includes string, plastic, hot color/foil stamping etc. Normal strings and plastic are not easy to fade after strict control. Simple test method: boiling water infusing 3-5 minutes. And some foreign trade orders will require professional test report. However, the hot color/foil stamping is difficult to control. At present, even if the best color foil imported can not guarantee the color will not fade,so it is recommended to use gold foil-like anodized aluminum or black & white, which can be used for transparent organic protection with high requirements and other colors.

It is best to have the same design style and main color in the packaging bag, brochure, tag, hanging grain and so on.
