A lot of farmers and growers have questions about the strength of poly tanks for there liquid fertilizer. Understanding what poly tanks are made from and how they compare with other materials is important.

What are Poly Tanks made from?

Poly tanks or plastic tanks are made from polyethelene. This raw material is a smooth powder that forms into plastic when it is melted. This is called roto-molding. This means that when the tank is in the oven getting cooked, the mold is spinning, spreading the powder evenly. Depending on the manufacturing process, you will get different plastic thicknesses in different spots.
