1. Reduce packaging. Packaging should meet the requirements of protection, convenience, sales, etc., and should be used in the minimum amount.
2. The packaging should be easy to reuse or easy to recycle. Through the production of recycled products, incineration and utilization of heat energy, composting to improve soil and other measures to achieve the purpose of reuse.
3. Packaging waste can be degraded (Degradable). Does not form permanent waste, and then achieve the purpose of improving the soil.
4. Packaging materials should be non-toxic and harmless to human organisms. Packaging materials should not contain toxic elements, halogens, and heavy metals; or the content should be controlled below relevant standards.
5. Packaging products must be comprehensively measured from the selection of raw materials, manufacturing, use, recycling and disposal of products to meet the requirements of ecological and environmental protection, and to maintain a virtuous circle in the natural ecosystem.
Green packaging materials In order to effectively implement the green packaging design, in the packaging structure, as far as possible to achieve removable type, in the selection of materials, it should be possible to use green packaging materials and design of long-life packaging materials, which can greatly reduce Contamination of the packaging after it is discarded. The four major packaging materials for modern packaging are paper, plastic, metal, and glass. Paper products can be recycled after use. A small amount of waste can be naturally decomposed in the natural environment. It has no adverse impact on the natural environment, meets the requirements of environmental protection, and can play a positive role in replacing the white pollution caused by plastics. For plastics, according to relevant data, it is estimated that the direct and indirect processing costs of a plastic waste can be up to 10 times its original value. Compared with the other three major plastic, metal, and glass packagings, and the quantitative evaluation by LCA technology, paper packaging is recognized as one of the most promising green packaging materials.
The current packaging of paper products includes paper packaging film, pulp molded products, edible paper products, corrugated paper boxes, and honeycomb paperboard. The raw materials of paper molding products are derived from waste paper and some paper pulp, and have a wide range of sources and low prices. Light weight, the biggest advantage is fully in line with the principle of environmental protection, easy to use after recycling, can be recycled and processed, even if it is abandoned, it is also easy to degrade, without any impact on the environment. Therefore, in recent years, in the green packaging materials, paper molding products have come to the fore and gradually replaced the foam plastic in a wide range of fields.
Paper Molded Products Environmentally Friendly Paper Molded Products are widely used in food (drug) products, electrical appliances, and are made of plant-based pulp or waste paper products that can be recycled completely and recycled. Packaging, planting seedlings, medical utensils, handicrafts billets and fragile liner packaging and other areas of pollution-free science and technology green products. Paper mold products are full of “green†from raw materials, production processes, and final waste disposal methods.
1. Green raw materials for the production of pulp molded products are paper-based, and most products are used waste paper. Waste utilization not only reduces resource consumption, reduces environmental pollution, but also greatly reduces costs.
2. The process of producing pollution-free paper products is the process of pulping the waste paper pulper, and then vacuum-assisted molding the mold in a special shape (similar to the shape of the package), and then transferred and removed. Molding, drying, molding and other processes, but in the entire production process, most of the physical process, even if you need to add a little reinforcing agent, waterproof agent, no effect on the health of workers and the environment, for the production of water There are two ways to go, one part is dried by evaporation and the other part can be recycled. The process technology is concise and practical, and there is no pollution source in the production process, which meets the requirements of environmental protection production.
3. Waste treatment Environmental-friendly paper mold products Packaging waste disposal methods have greater flexibility to recycle and reuse paper or continue to make paper-molded products; also can be naturally degraded and used as fertilizer to increase soil organic matter; and if it is needed urgently In the case of processing, it can also be burned and no toxic gas is produced. This fully reflects the distinctive characteristics of easy recycling of waste paper products.
4. Applications The diversified paper mold products have many fields of use, large market capacity, and rich potential for excavation. They are widely used in food, medicine, and cosmetic fields. At the same time, a compatible paper mold production line can produce products with different uses as long as it is slightly improved on the mold. Its diversified functions and recycling features make many products unattainable. In addition, products with different thickness, strength, whiteness, and precision can be processed according to the nature and grade of the packaged goods, which can save packaging costs and improve economic efficiency. This effectively reduces the sources of pollution in our lives.
In short, the development of green packaging is a major trend in the world packaging industry. Many countries have already established environmental protection measures in the form of legislation and have promoted the implementation of environmental protection policies in terms of policies, technological development, and the collaborative relationship between theories and companies and consumers. For example, the packaging and environmental protection regulations promulgated by the European Community in 1991 stipulate that plastic polystyrene (EPS) plastics should be avoided in transport packaging and sales packaging and replaced with pulp molded products. China must comply with the requirements of global environmental protection trends, speed up the establishment of a green packaging industry system, and make packaging “green†as quickly as possible to meet the challenges of countries’ technological walls, environmental walls, and quarantine inspection rules. The main demand is for the rapid development of paper molding products. .
