Ecological packaging materials

Eco-packaging materials, in a broad sense, include the following three aspects: First, the consumption of environmental resources is less when manufacturing materials; second, it is to ensure that the materials have good comprehensive performance in production and use; and third, the use of materials is abandoned after use. Can be recycled or reused, or have less pollution to the environment. Eco-packaging materials are "small-scale generations" in the field of ecological materials, but the content involved is very extensive. It includes natural materials, metal materials, non-metallic materials, polymer materials, and composite materials. Due to the short cycle of the ecological cycle of packaging materials, this has aroused the attention of material experts. Some developed countries have done a lot of work on the research of ecological packaging materials.

In recent years, experts have explored the law of environmental changes caused by packaging materials, developed packaging materials that can protect the ecological environment, studied the theory of self-decomposing and degrading of recyclable plastic packaging materials, and developed methods for the research and development of non-polluting packaging materials. , processing technology and manufacturing technology provide the theoretical basis. Experts proposed that from the perspective of the environment, we must re-evaluate and study the rationality of existing packaging materials systems, as well as the physical and chemical properties and special functions of packaging materials. This requires a reconsideration of the constituent components, processing techniques, physicochemical properties, and main uses of the packaging material.
