China's canning industry has broad prospects for development, but the difficulties facing it also restrict the development of China's canning industry.

1. Excessive dispersion of industries, most of the canning enterprises are mainly small and medium-sized enterprises, private enterprises, and have not centralized industrial production;

2. Lack of innovation in the industry, a lot of enterprises follow the wind to make similar products, although the price is low, but consumers are prone to visual fatigue;

3. With the continuous improvement of the price of raw materials such as iron and aluminum and aluminum, canning enterprises should also raise the cost of making metal cans, resulting in waste of resources.

4. Lack of genuine national brands. Most canning enterprises are mainly for the large enterprises in the upstream, rarely create their own brands, to dig deeper into the needs of customers, and strive to create benefits for customers.

At present, China's packaging machinery products are facing fierce international competition due to the lack of variety, low technology level and poor product reliability. In the past five years in particular, we have accelerated the development of deep-processing agricultural products, the construction of economical society, the development of circular economy and the strengthening of technological innovation, resulting in a new wave of technological import. For example, the total investment of deep processing of agricultural products in China in recent years reached more than 32 billion yuan, and more than 80% of the processing and making equipment was imported.

In recent years, there have been some new features of second-hand canning equipment in foreign countries. The development of packaging machinery in China mainly focuses on corrugated board production line, box (box) and printing complete equipment. Environmental protection packaging machinery, etc. For the packaging of mechanical and electrical products, we will focus on the pilot work of "specialized fixed point, qualification certification, uniform standard, international integration and export expansion".

In recent years, canning equipment abroad has new features, mainly: one is production efficiency. The production line is highly automated and the production scale is large to obtain the best labor productivity and economic benefits. Second, the high utilization rate of resources and the comprehensive utilization and development of circular economy; (2) the product attaches great importance to energy conservation and reduces cost. Fourth, high and new technology is practical, improve production efficiency, product level, grade; Fifth, the commercialization of scientific research results, the packaging machinery products to the knowledge intensive, the technical synthesis, the product intelligence and so on development.
