PVC Cling Film is also polyvinyl chloride. Due to the production process, PVC cling film will add a lot of plasticizer during the production process, which is the plasticizer we usually say. If the PVC cling film is heated or in contact with grease foods, the plasticizer contained in the PVC wrap film is easy to precipitate, and the food is brought into the human body, causing certain harm to the human body and even causing cancer. However, PVC cling film is used for preservation of fresh fruits and vegetables, and there is no problem.

The development time of the packaging machinery industry in China is also 20 to 30 years, but it has become the focus of the industry development. At present, the global machinery and equipment market demand is growing rapidly at an annual growth rate of 5.2%. In the next few years, packaging equipment is developing. China's market sales will exceed that of developed countries such as Japan and the United States. According to the prediction of the China Machinery Industry Federation, during the "Twelfth Five-Year Plan" period, the scale of China's packaging machinery industry is expected to exceed 600 billion yuan, and the average annual growth rate will reach 16%. It can be seen that in the future development, China's packaging industry has good opportunities, but this is in the case of the packaging machinery industry to keep up with the trend of the industry.
In recent years, China's economy has developed rapidly. As a part of China's many industries, packaging machinery is used in many production experiences. Filling machines, sealing machines, packaging machines, labeling machines, coding machines, etc. It is used in many industries such as food, medicine, cosmetics, beverages, and medicine. After decades of development, the packaging machinery industry has become one of the top ten industries in the machinery industry. It has an important position in the domestic market and is also a part of the rapid development of the national economy.
However, at the same time as the rapid development of packaging machinery in China, there are also many problems. Most of China's packaging machinery enterprises only repeat production on low-level products. Therefore, if packaging machinery enterprises want to develop for a long time, they must recognize their existence in time. The problem. Looking at the packaging machinery industry still has many problems. The small scale of the enterprise, low product level, excessive dependence on imports, low development capability, insufficient R&D investment, and lack of professional and technical talents all restrict the development of China's packaging machinery industry. However, China's packaging machinery is not at all worthwhile compared with foreign advanced equipment. For example, China's packaging machinery is more flexible in design and design, and can be tailored according to the different needs of customers. It has the advantage of geographical environment and can pass many Kinds of channels to understand the problems of equipment in the actual production of the enterprise, to build a complete excellent after-sales service system, to solve problems in a timely manner; according to customer requirements, the manufacturing and commissioning cycle of the equipment is shorter than foreign, and the cost is low, and maintenance is convenient.
Technology to help packaging machinery products upgrade China's packaging machinery industry has great potential for development. With the continuous development and advancement of technology, future microelectronics, computers, industrial robots, image sensing technology and new materials will be more and more in packaging machinery. With a wide range of applications, companies need to learn and introduce new technologies to enter the packaging equipment with high production efficiency, high degree of automation, high reliability, flexibility and high technology content. To create a new type of packaging machinery, packaging machinery to the direction of integration, chemical, intelligent and other development.
The high efficiency of efficient food processing is mainly realized by mechatronics technology and light, electricity, liquid, and automatic control technology. The continuous production equipment replaces the intermittent production equipment, and the specialized production equipment replaces the general production. Equipment, replaced by small and medium-sized production equipment by humanized production equipment. Continuous production, specialized operation, automatic adjustment, and large-scale operation of the production line can significantly improve production efficiency and economic benefits. At present, many food machinery large-scale manufacturing enterprises or multinational companies, most of them develop production lines with high automation and large-scale production lines to achieve market competitiveness.
Since the beginning of the 21st century, compared with traditional packaging machinery and equipment, the new food packaging machine has the characteristics of simplicity, high productivity, better support and more automation. Future packaging machinery will cooperate with the trend of industrial automation to promote the overall level of packaging equipment. New intelligent devices such as high-intelligent CNC systems, encoders and digital control components, and dynamic load control have been widely applied to packaging machinery and equipment, making equipment users more independent, flexible, operationally correct, and operating. And compatibility.
It is understood that the countries with high levels of foreign packaging and food machinery are mainly the United States, Germany, Japan, Italy and the United Kingdom. German packaging machinery is in a leading position in design, manufacturing and technical performance. In recent years, the development of packaging and food machinery equipment in these countries has shown a new trend.
China's packaging machinery industry still needs to improve the historical legacy
[ppzhan abstract] In recent years, driven by economic development, China's packaging industry continues to develop. Now China has become the second largest packaging country in the world, and is cooperating in various aspects to promote the transformation of China from a packaging country to a packaging power. This must first solve some historical problems.
