China Pulp Molding Industry Status and Countermeasures

Pulp molding is a processing method in which pulp is used as a raw material and a filter with a screen is used under conditions of pressure (negative pressure or positive pressure) to dehydrate the pulp and form fibers to produce a desired product. Pulp molding process mainly includes pulp preparation, mold forming and drying processes. Die forming includes vacuum forming and extrusion. At present, the vacuum forming method is commonly used in China's pulp molding industry, and only a few companies use the extrusion method. As the paper pulp used in pulp molding uses waste paper as raw material, it conforms to the environmental protection requirements and the development direction of green packaging. As early as in the beginning of this century, pulp molding has emerged in developed countries, but due to various reasons, it has only recently attracted attention in various countries. At present, the pulp molding industry in France, the United States, Japan, Canada, Iceland, the United Kingdom, Denmark, Singapore, the Netherlands and Other countries have reached a considerable scale. China's pulp molding industry started relatively late and has a history of more than 10 years, but it has developed rapidly. At present, there are more than 300 manufacturers engaged in the research and production of pulp molding technology from less than 100 in 1995; the production equipment has also evolved from a reciprocating stamping single machine to an automatic production line; the product category consists of simple egg trays, The low-grade products such as fruit trays have been developed into industrial products and food packaging; the process technology has evolved from the simple recycling of the original waste paper into a non-toxic, odorless, water-repellent, oil-resistant and disposable disposable high-end tableware product. According to industry sources, some of the performance indicators of China's pulp molding production process and production equipment have reached the world's leading level. Marketing has also developed from internal sales to internal and external sales. Pulp molded products have entered the international market together with their packaging products. market. With the continuous improvement of people's environmental awareness, the market prospect of pulp molding industry is very broad. Although China's pulp molding industry has developed rapidly in recent years, there is still a clear gap compared with developed countries. The specific performance is as follows: 1. The proportion of pulp molded products used in packaging in China is far lower than that of developed countries in the world. According to the statistics, at present, the proportion of pulp molded products in the packaging of industrial products in China is less than 5%, while that in industrialized countries is as high as 70%. The use of foamed plastic products in China's industrial product cushioning materials is still very large. Many electronic products, household appliances, and electromechanical products are still used in large volumes, are difficult to recycle, have high recycling costs, waste cannot be naturally weathered, and are incinerated to deal with environmental pollution. Foam is used as a cushioning material. According to statistics, currently only the color TV sets and the color picture tube consumes 20,000 tons of EPS foam plastic per year, and the volume is about 1 million cubic meters. The annual consumption of EPS foams in the electronics industry and other industrial industries is considerable. Second, the pulp molding companies do not have enough market research to not only not guide market consumption, but even to meet market needs. At present, many users such as pulp molding companies have come to the door to actively understand the market demand. It is unclear what kind of pulp molded products are needed in the market, and little is known about the development trend of pulp molding packaging. This is also an important reason why pulp molded products still cannot replace foam. Due to the lack of market research, some companies have had to switch production or even shut down after blindly producing for a while. Third, the structural design, mold design and processing equipment of pulp molded products still cannot meet the needs of further development. At present, China's products are increasingly becoming an international market. However, the structural design and mold design of pulp molded products are often in line with China's national conditions, but they cannot meet the needs of foreign countries. The serialization and standardization of pulp molded products has progressed slowly and has not kept pace with the changing market demands. With the acceleration of the pace of product replacement, some companies' production equipment can not meet the needs of new product production, resulting in the market's need for products can not be produced, but can not produce the product market. According to the development status in recent years, China's pulp molding industry must catch up with the developed countries as soon as possible, and it needs to intensify efforts in the following areas. The first is to improve the technological level of the development of pulp molding equipment, so that the molding equipment will continue to meet the packaging needs of various products. For example, equipment for the production of fast food boxes, in addition to meeting the needs of production, must also consider hygiene requirements to ensure that the products produced meet the needs of the end user. This requires that this issue be considered in the production of equipment from the production of materials to the production of pulp molded products in the workshop. The second is to make full use of the latest scientific and technological achievements, actively adopt computer-aided design and auxiliary production, and constantly improve the level of product structure design and mold processing capabilities. The development of the pulp molding industry is inseparable from the progress of science and technology. It is necessary to introduce new technologies. At the same time, according to the changes in the domestic and foreign markets, it is necessary to strengthen the exchange of industry information and organically combine scientific research, design, development, production, promotion and application. The third is to formulate and improve the standards for pulp molded products, strengthen testing methods, and improve product quality. Although the pulp molding industry has done a lot of work on standardization, the two national standards for disposable degradable tableware have been officially implemented since January 1st this year, but they still cannot meet the requirements of the rapid development of the industry. The specific measures of relevant departments have never been implemented. The introduction has affected the implementation of the standard. At the same time, according to two mandatory standards, there are many items that need to be tested in pulp molded products. No testing department has been able to detect all of them. This is not conducive to the implementation of standards. Coupled with the current high cost of testing pulp molded products, many companies are reluctant to send inspections, resulting in product quality can not be guaranteed.
