The development trend of green packaging in the global market

at present, there is a global trend of "green packaging". In this regard, European governments attached great importance to it and formulated packaging laws one after another. Germany, the first country to advocate recycling of packaging materials, formulated the "circular economy law", and Denmark took the lead in implementing the "green tax" system; Many countries require manufacturers, importers and retailers to take responsibility for recycling and remanufacturing packaging materials

at present, among the "green packaging" popular in domestic and foreign markets and most admired by consumers, there are paper packaging, degradable plastic packaging, biological packaging materials, etc. For example, "artificial peel" is a new kind of paper in the future. Like eating oranges, people peel off the peel and eat it immediately. At the same time, the waste can be recycled. At present, edible fruit and vegetable liquid fresh-keeping film has been used in fruit and vegetable packaging in China. In this century, people can plant and harvest natural biodegradable plastic products just like planting wheat and potatoes. With the rapid development of science and technology and people's increasing attention to environmental protection, packaging paper is developing towards functionality

anti corrosion: paper made of calcite and activated carbon can be used to make corrugated boxes for transporting flowers, which can absorb hydrogen sulfide that causes flowers to decay

bacteria prevention: inject sterile gas when manufacturing natural pulp. This paper has the function of preventing bacteria from invading and can be used for the packaging of medical instruments

anti oxidation: paper made of weak alkali beating can protect calligraphy, painting and books from erosion in acid environment

moisture resistance: waxed paper can improve the moisture resistance. It can be used to make rainproof bags and dew proof bags for fruit tree seedling cultivation

deodorization: paper made of porous inorganic substances and organic flavonol can absorb ammonia and other odor

heat resistance: cardboard made of specially treated pulp has good heat resistance and water vapor absorption performance, and can be used as a packaging box for microwave food

fire resistance: it is made by mixing aluminum hydroxide and natural pulp; Or it is made of phosphorylated pulp and glass fiber, which has good flame resistance

acid resistance: paper made by mixing special pulp and additives has excellent shading and acid resistance

oil resistance: after oil resistance treatment, the inner layer of the paperboard can prevent oil from soaking, and the surface of the paperboard can be printed with general paint treatment. This kind of paperboard is mainly used for the packaging of greasy food

water resistance: paper made of 100% natural pulp mixed with latex resin has excellent water resistance, folding resistance and friction resistance

water sensitivity: the paper treated with special coating makes the white paper transparent immediately after absorbing water, and the contents can be seen through the packaging without unpacking

fresh keeping: natural pulp is overloaded with absorbent resin after chemical treatment. It is suitable for fresh-keeping packaging

no obvious fatigue limit as metal material 1; Silencing: low density paper made of non carcinogenic asbestos fiber, waste paper, rags, etc., with superior sound absorption, water absorption, heat insulation and cushioning effects
