The extrusion blowing process for the production of cosmetic containers, that is, the plastic raw materials are added to the extruder, heated and melted to plasticize the molten parison, and then placed in the bottle mold for inflation molding. After getting the finished product.
This process is mainly used to produce polyethylene, polyvinyl chloride plastic bottles. Spray bottles are mainly used in pharmaceutical bottles, cosmetic containers and chemical bottle packaging markets. Through the control technology of spray nozzles on sprays, it is possible to grasp the dosage level well.
Environmentally friendly and practical spray bottle equipment: it consists of a sturdy bottle body and a replaceable bottle bottom.
