Blowing moulding, also known as hollow blow moulding, is a rapidly developing plastic processing method. During World War II, blow moulding began to be used in the production of low density polyethylene bottles. In the late 1950s, with the birth of high density polyethylene and the development of blow moulding machine, blow moulding technology has been widely used. The volume of hollow containers can reach thousands of liters, and some of the production has been controlled by computer. Plastics suitable for blow moulding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The hollow containers obtained are widely used as industrial packaging containers. According to the method of parison making, blow moulding can be divided into extrusion blow moulding and injection blow moulding, and the newly developed multi-layer blow moulding and stretch blow moulding.
