The development of green packaging and printing by carton printing plants is a concrete manifestation of circular economy in the packaging and printing industry. It is an essential requirement for the development of circular economy and a comprehensive and coordinated view of sustainable development. It is a powerful measure to build a resource-saving society and promote harmony between man and nature. . As a member of the packaging and printing industry, we must understand the importance and urgency of the development of circular economy from a strategic perspective and use an overall perspective to further enhance our consciousness and sense of responsibility. It is imperative to vigorously develop green packaging and printing!
Promote the increase in tea packaging printing?
First of all, packaging and printing plants need to pay attention to the safety of the selection of materials. This is the basis for whether the tea packaging is more refined. Only on this basis can we further study how to improve the printing of tea packaging to be more refined. Tea packaging and printing companies must choose high-safety paper and ink. Pay attention to the paper not to be too thin, otherwise it will not be good for packaging tea. At the same time, pay attention to the number of grams of paper not to be too large. This is not only a waste of money, but also a waste of printing costs. When it comes to ink selection, safety comes first. At the same time, we should also pay attention to the relevant characteristics of the ink.
The main components of paper are cellulose, sizing material, fillers and so on. The flowing part of the ink is the binder, and the pigment of the ink is attached to the surface of the paper by conjunctivation and drying by the binder. The main components of paper and ink are asymmetric molecules. When they are close to each other, they rely on the secondary binding force to make the molecules adhere to the paper. At present, the packaging and decoration printed products of packaging and printing companies mostly use coated white paper, wood pulp linen white paper, ordinary liner paper, wood pulp linen liner paper, kraft paper and white cardboard. Due to the differences in the production processes of different paper mills, the whiteness and smoothness of the paper surface are significantly different.
