The era of e-commerce has promoted the widespread application of paper packaging. The output value of the paper packaging industry last year alone was 330 billion yuan, accounting for half of my country's total packaging output value. However, although traditional paper packaging has great use value in the market , but environmental pollution is also an indisputable fact, so people began to advocate the use of more environmentally friendly metal packaging.

There are many types of paper packaging and a wide range of uses. It can be divided into corrugated paper, paper bags, and internal and external packaging such as cards and laminates. Among them, the corrugated paper industry is the largest, accounting for about 1/3 of the output value of the paper packaging industry. It has a narrow upstream and a wide downstream. The characteristics are that the upstream carries the papermaking industry, and the downstream connects fast-moving consumer industries such as food and beverages and daily chemical products, and durable consumer goods industries such as electronics, home appliances, and industrial precision parts.

However, the paper packaging industry is also facing large-scale closure and consolidation. The sluggish demand has led to a sharp contraction in the scale of the industry. This phenomenon is mainly due to the following two factors:

(1) The paper packaging industry is a midstream industry with low concentration. The upstream paper industry is highly concentrated and has more bargaining power, so the space for paper price decline is limited.

(2) At present, our country is in an economic bottom period, and the growth rate of various downstream consumer goods industries has slowed down.

At the same time, in the four-step production process of paper packaging pulping, papermaking, coating, and processing, pulp is the main source of pollution in the production of paper products. Alkaline pulping will produce papermaking black liquor, that is, lignin, polypentose and Mixtures of total alkalis account for more than 90% of the total pollution emissions from the papermaking industry. They are highly concentrated and difficult to degrade. They are currently a major problem for the papermaking industry in reducing pollutant emissions.

In response to the difficult-to-solve problem of pollutant emissions in the paper industry, Jiangze metal turnover boxes, metal mesh boxes and other metal packaging have replaced traditional carton packaging. In response to the country's call for environmentally friendly production, the industry is encouraged to use recyclable metal packaging products. Timber-saving logging saves the country tens of thousands of adults every year. In addition, the "rent-to-purchase" operating model advocates the standardization of metal turnover boxes and cages in the industry and the joint construction of public unitized circulation systems to maximize product packaging, save energy and reduce consumption, and reduce the production and emission of pollutants.
