Biodegradable plastics have become popular in green packaging

March 13 - Frost Sullivan, a famous consulting company in the United States, recently released an analysis report on the biodegradable packaging market in North America. According to the report, with people paying attention to environmental protection and health, biodegradable plastics are in increasing demand in the packaging field, and manufacturers will also increase production capacity. It is expected that the market demand for biodegradable packaging materials will continue to grow in the next few years

biodegradable materials can be decomposed by microorganisms in nature. As packaging materials, the amount of garbage can be greatly reduced. Due to its good preservation effect, about 41% of biodegradable packaging is used for food preservation. Since the 1990s, the global production of biodegradable plastics has increased rapidly, of which about 60% is used in the packaging industry. It is estimated that by 2011, the output of biodegradable plastic packaging will reach 116000 tons, with an average annual growth rate of 22%

green packaging is encouraged by policies

the development of green packaging is mainly supported by the following factors: on the one hand, biodegradable plastic packaging has the advantages of energy saving, environmental protection and recycling. On the other hand, the North American market, government departments, circulation channels and other forces have developed micro foaming injection molding grade with good surface appearance quality in Jinmin. PP actively promoted the application of this new technology in February this year. In the next two to three years, the market demand for biodegradable plastics will gradually strengthen

due to the large amount and wide range of use of traditional plastic packaging, its pollution to the environment is becoming increasingly serious, so the environmental protection departments of various countries have formulated a series of policies and regulations to restrict the production and use of plastic packaging, which undoubtedly brings severe challenges to the developing plastic industry. In recent years, with more and more attention paid to green packaging, the U.S. government began to encourage the production of biodegradable plastic packaging for the sake of promoting environmental protection

in addition, there is support from terminal retailers. In the United States, a large number of plastic bags are treated as garbage every year, and only a small number of plastic bags can be recycled, resulting in a lot of pollution. In order to solve this problem, paper packaging bags appeared in the mid-1990s, but they are not durable in wet environments. At present, many retailers in the United States and Canada support the promotion of biodegradable plastic packaging by giving discounts to customers who use environmentally friendly packaging

the low cost performance still needs to be tackled.

as an emerging industry, biodegradable plastic packaging industry is also facing many challenges. First, the packaging technology is not mature enough. Although consumers' attention to biodegradable plastic packaging is gradually increasing, compared with traditional plastic packaging technology, this packaging technology is still relatively backward. Secondly, the application field of biodegradable plastic packaging is limited. Although biodegradable plastic packaging occupies a monopoly position in the field of food preservation, its thermal insulation, waterproof, sealing and other properties are slightly inferior to traditional plastics, so its penetration rate in other downstream fields is low. Thirdly, consumers' awareness is not high. In addition, the high price also hinders the application of the product

as the raw material of biodegradable plastics, the price rise of corn, wheat and other agricultural products has also promoted the price rise of biodegradable plastics. In terms of price, the cost of petroleum based plastics was lower than that of biodegradable plastics in 2007. For example, the packaging grades of polyethylene and polystyrene are 0.65 ~ 0.85 dollars/pound, while the degradable polylactic acid plastic is in the range of 1.75 ~ 3.75 dollars/pound, and the starch derived polycaprolactone is 2.75 ~ 3.5 dollars/pound. Even under the current oil price decline, the price of biodegradable plastics is still 2.5 ~ 7.5 times higher than that of traditional petroleum based plastics

vigorously guide and cultivate the market

the improvement of people's awareness of environmental protection has enabled manufacturers to see opportunities for biodegradable plastics in the packaging market. DuPont, Cargill, BASF and other well-known chemical manufacturers have entered the market through mergers and acquisitions and joint ventures. In view of the low recognition of the current consumer's quotation for the impact testing machine of biodegradable plastics, which is usually based on the size and performance of the test box, it is necessary to vigorously cultivate the market and guide consumers in the future. Biodegradable plastic is a new type of packaging material. Plastic and packaging manufacturers need to work together to publicize and guide consumers to accept this environmentally friendly material

recently, natural works, a subsidiary of Cargill in the United States, has made a major breakthrough in the production process of inger natural plastics and fibers, which are produced from 100% renewable plant resources. Compared with the old products, the carbon dioxide emissions of new products are reduced by 60%, and the energy consumption is also reduced by 30%. According to the promotional materials of NatureWorks, this product not only meets the market demand for both functionality and environmental protection of plastic and fiber products, but also makes the company take a big step forward in environmental protection
