Outer packaging labels refer to the labels attached to product packaging or packaging boxes. They are one of the important publicity and promotion tools for enterprises, and are also a reference for consumers to choose products. With the intensification of market competition and the diversification of consumer demand, packaging labels are a kind of identification or label used for goods packaging. The label should indicate the product's specifications, ingredients, production date, shelf life and related quality certification information, so that consumers can understand the basic situation of the product. The material has excellent weather resistance and adhesion, and can withstand the erosion of various diluents and chemicals in different environments, playing an important role.
