Although everyone is a barrel, and everyone is a packaging barrel, it is clear that you can easily find the difference between the two from the name.
One, the same is the packaging barrel, one is used to hold paint, and the other is used to hold thinner. This is obviously different in the material of the barrel. Therefore, there will be a difference on the inside of the barrel. Generally speaking, the inside of the paint packaging barrel is relatively smooth, because the paint has a relatively large adsorption force, and there is no special requirement for the thinner packaging barrel.
Second, as a paint packaging barrel, it is mainly used to hold paint, or it can be said to be a container. Many of them are made of iron sheet, and there will be a layer of anti-rust packaging coating on the surface. Such barrels generally have pressure bearing requirements and rust prevention requirements for the container.
