Packaging printing: material selection and environmental protection requirements

Packaging printing: material selection and environmental protection requirements

In packaging printing, the selection of materials and environmental protection requirements are crucial. This not only affects the quality of the product, but also affects the sustainable development of the enterprise.

First, the selection of packaging and printing materials should be based on the principle of environmental protection and sustainability. Some common packaging and printing materials include paper, plastic, metal and glass. Among them, paper is one of the most commonly used packaging materials, because it can recycle and reuse, which has good environmental protection. At the same time, cowhide paper has high tensile force, high tear resistance, rupture and dynamic strength, tough texture and low price, so it is widely used in the production of various packaging paper and paper bags.

Copper paper is also known as printing coating paper. It is applied on the surface to increase smoothness and luster. It is suitable for color printing. It is often used in plastic printing, cave print fine network cable printing, such as high -end albums and illustrations in books and periodicals. White plate paper is a cardboard with a white and smooth back, and the back is mostly ash. It is mainly used for single -sided color printing and made of carton for packaging. The whiteboard paper texture is hard and thick, and has good standing strength, surface strength, discount resistance and printing adaptability.

However, some of these materials have environmental impact problems. For example, plastic is not easy to degrade, and excessive use may lead to environmental pollution. Therefore, when choosing a packaging printing material, it is necessary to give priority to recyclable materials that can be recycled, degraded or reused. At the same time, minimize unnecessary packaging and materials to reduce the impact on the environment.

Secondly, the environmental protection requirements of packaging and printing materials are also reflected in the production process. During the production process, we should pay attention to energy conservation and emission reduction and resource recovery. For example, printed materials such as hydrophilic ink or UV curing ink can be adopted; cyclic reuse production methods can be used to reduce the production of waste; digital and intelligent production processes are used to improve production efficiency and resource utilization.

Finally, enterprises should actively promote the green transformation of packaging and printing materials. This can be implemented by establishing a green supply chain, implementing green procurement policies, and increasing the research and development and application of green packaging materials. At the same time, enterprises can also improve their environmental protection image and social responsibility by carrying out environmental protection public welfare activities and strengthening cooperation with related industries.

In short, in packaging printing, the selection of materials and environmental protection are inseparable. Only by focusing on the principles of environmental protection and sustainability can we realize the sustainable development of the enterprise and the protection of the ecological environment. Therefore, in the future packaging and printing industry, we need to pay more attention to the practice and application of the principles of environmental protection and sustainability.
