Main Raw Material Of 20l Barrel Mould

  • 20L Bucket Mould is one of our common barrel mold specifications. What are the general materials used in barrel molds?

    The main raw material for the production of plastic barrels is polyethylene, or PE for short, which is a high molecular organic compound made by addition polymerization of ethylene. Polyethylene is recognized as the best material in contact with food 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. Known as the "flower of plastic", it is the most important and most important part of plastic packaging printing. material.

    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. Heat-resistant and steam-boiled, cold-resistant and freeze-resistant, moisture-proof, gas-proof, good insulation performance, not easy to break, and the strength is twice that of LDPE.

    The 18L Bucket Mould material is the same, but the specifications are different.
