Analysis of the internal elements of green packaging

due to the continuous improvement of people's environmental awareness, green and environmental protection are increasingly concerned by people. Therefore, there is a fashionable topic in society: green packaging. Therefore, designers have a higher design pursuit, that is, to make packaging protect products, but also to reduce its environmental pollution. In the design process, the designer firmly grasped the internal elements (packaging materials) and external elements (structural modeling, image, color and text, etc.) of the design, consciously gave and improved people's awareness of green environmental protection, and promoted the whole process of green environmental protection packaging

internal elements of green packaging

under the advocacy of green environmental protection thought, designers have higher requirements for the internal elements of green packaging packaging materials. They followed the principle of 5R + 1D and made a targeted choice of materials:

1. Packaging lightweight

refers to minimizing the use of packaging materials under the conditions of meeting various functions. It is understood that experts have shown in the strength test of corrugated board that if the quantity of corrugated base paper increases by 1g/m2, the quantity of carton board can be reduced by 1g/m2. Therefore, using this method in the production process of corrugated board can realize the lightweight of packaging. For example, Budweiser adopts 185g/m2 coated paperboard produced by M-real company of Finland as the face paper of corrugated board. It is a kind of thin paperboard with low weight and high strength (edge compression strength and burst resistance), and has good printing [encyclopedia Weibo] adaptability. Using this paperboard and carton pre printing technology, the gram weight of the carton is reduced by 30%, the packaging cost is reduced by 20%, and the strength of the carton is increased by 10%, and the printing effect is greatly improved. It can be seen that the lightweight of packaging materials is favored by businesses

2. Material recyclability (return)

refers to the recycling, reuse and processing of used packaging products into new packaging products. At present, the technical problems related to the recycling of paper packaging materials have been basically solved, and the recycling of single plastic products (PE, P, etc.) has also made great breakthroughs, but there are still some problems in the recycling technology of some composite plastics. For example, aluminum-plastic composites are widely used in the packaging of many products such as food and medicine because of their good surface finish, good moisture resistance, and the barrier, oxidation resistance and printability of jc/t547 (2) 005 ceramic tile adhesive. However, how to effectively separate aluminum and plastic has always been a problem. Through continuous efforts, the high tech Research Institute of Shenqiu County Association for science and technology in Henan Province recently developed the recycling technology of waste aluminum plastic packaging, so that the waste aluminum plastic packaging that is not easy to recycle can not only separate plastic, but also produce aluminum. The success of this technology has made another important step in recycling

3. Material reuse

refers to the recycling of all or part of the used packaging products, and it is not easy to give up the reusable packaging products, so as to reduce the production of packaging products. Since February, 2003, all maintenance service stations of Epson Co., Ltd. have used environmentally friendly packaging and equipped with environmentally friendly distribution. The packing box is made of 100% compressed recycled paper, which is not only durable, but also reusable. The environmental protection packaging and distribution service is to use the above materials to transport the printer sent by the customer for repair. When the product is delivered to the customer, the packaging box is brought back by the distribution personnel to realize reuse. Moreover, when the company adopts the recycling of packaging boxes for large output machines, it will recycle the packaging boxes according to the time required by customers. In order to make it easier to recycle the packaging boxes, they changed the raw materials of the boxes from the previous synthetic materials to a single raw material (cartons), which not only saves resources, but also reduces costs

4. the material can be almost blank in most places; On the other hand, China's industry has developed rapidly in recent years. Recycling refers to the recycling and reprocessing of used packaging products, so that they can be used in different fields. As there are a series of problems in the recycling technology of composite materials, businesses began to use some packaging materials made of single materials, which are conducive to recycling, in order to realize the recycling of materials. At present, a pure polyester beverage bottle without a high-density polyethylene base has appeared in the market before being measured into two mixing/injection mixing heads, and pulp molding packaging can be used to replace some traditional plastic products that are difficult to degrade. For example, a company in the United States developed a new model of waste recycling in the new era

5. Refusing to use non ecological materials (refuse)

refers to refusing to use packaging products that are not conducive to ecological development or can cause the spread of diseases and pests. In terms of packaging materials, some developed countries as importing countries prohibit or restrict packaging products (wooden cases, straw bags, etc.) made of some original packaging materials and some recycled packaging materials. For example, since September 1998, the United States has required all wood packaging and wood bedding materials from China to undergo high-temperature treatment, fumigation or preservative treatment, otherwise they will be refused entry. Since January, 1999, Canada has also strictly controlled the wooden packaging materials used in imported goods from China, requiring that they must be treated with insect prevention in advance and accompanied by certificates issued by relevant Chinese authorities. In order to solve these problems, China has adopted honeycomb paperboard packaging technology, which has the advantages of light, strong, rigid and stable, setting off a wave of honeycomb paperboard in China

6. material degradable

refers to that in order not to form permanent waste, non recyclable packaging waste should be decomposed, and the purpose of improving soil should be achieved through fertilization. Pulp molded products are a typical multi-functional degradable products. Pulp molded lunch boxes have the advantages of heat preservation, heat insulation and compression resistance. Pulp molded trays have excellent positioning, cushioning, air permeability and fresh-keeping performance. The nutritional bowl made of pulp molding plants are planted in the bowl and transplanted outdoors as a whole after they become seedlings. The nutritional bowl decays into fertilizer, which helps the plants thrive. These pulp molded products are favored by consumers and businesses
