Plastic Bucket Mould is one of our main products. The main raw material for the production of plastic barrels is polyethylene, or PE for short, which is a polymer 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. It is known as the "flower of plastic" and is the most important and most important for 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. It is heat-resistant and steam-boiled, cold-resistant and freeze-resistant, has good moisture-proof, gas-proof, and insulating properties, and is not easy to be damaged. Its strength is twice that of LDPE.
The general process of making plastic barrels is as follows: raw material preparation, blow molding, injection molding, demoulding and trimming, waste crushing, drying, assembly, final inspection and storage.
