Plastic barrels are widely used, are not fragile, rust-free, and light in weight. They have excellent oil resistance and strong corrosion resistance. They are recognized by various industries, and their quality also depends on its production materials.


The main raw material for the production of plastic barrels is polyethylene (PE), referred to as PE, which is a high molecular organic compound made by addition polymerization of ethylene. Polyethylene is a recognized food contact material in the world. It is non-toxic, tasteless and odorless, and meets food packaging hygiene standards. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness, and excellent heat sealability. It is known as the "flower of plastic" and is an important material for plastic packaging printing.


High-density polyethylene, referred to as HDPE. The density is 0.941~0.965g/cm3. It is polymerized by low pressure, so it is also called low pressure polyethylene. Milky white. It can be processed by blow molding method and T die extrusion process. It is heat-resistant and retortable, cold-resistant and freeze-resistant, has good moisture-proof, gas-proof and insulating properties, and is not easy to break. The selection of raw materials is very important in the production process. Products made with good raw materials are more durable.
