The application market competition of Metal Pails and plastic drums

The application market competition of Metal Pails and plastic drums

200L Metal Pails have two forms: open Metal Pails and closed Metal Pails. 200L Metal Pails are its mainstream products, and there are also small Metal Pails as small as 4L. The capacity of plastic drums ranges from 5L to 200L, or even as large as 1,000 liters. Plastic drums and Metal Pails have common application fields, but also have their own areas of advantage.

1. Petroleum product packaging

At present, although the number of oil pipelines and oil tanks is gradually increasing, Metal Pails are still the main packaging form of petroleum products, and most of them are 200L closed Metal Pails.

The 200L steel drum cannot be filled with oil, only to 80-90 percent of the capacity. In the process of injection and pouring out, the gas space in the barrel will decrease or increase accordingly. The special ventilated barrel plug for foreign countries is designed to maintain the balance of the pressure inside and outside the barrel, so as to prevent the inner pressure of the steel barrel from being too high and bursting. The effect of leakage. Metal Pails perform better than plastic drums in harsh shipping environments. For example, its high temperature resistance is good, and it is not easy to deform or even melt in high temperature like plastic barrels. It is estimated that the national output of 200L steel barrels in 2021 may exceed 120 million.

The 200L plastic barrel was introduced in China in 1988. At first, merchants questioned whether it could be used as a packaging for petroleum products. Later, because plastic barrels also have certain advantages in this regard, such as being able to withstand greater mechanical pressure, low cleaning costs and reusable warehouses, their market demand will not increase. At present, the annual output of 200L plastic barrels in the country is expected to be more than 50 million.
