High-density polyethylene is a non-toxic and odorless polymer material, which is an important packaging form in the pharmaceutical, daily necessities, and food industries. With the continuous improvement and perfection of various processing techniques, the shape of this bottle is constantly changing.
The raw materials of high-density polyethylene bottles have good processing properties, good wear resistance, electrical insulation, toughness and cold resistance. They are insoluble in any organic solvents at room temperature, and are resistant to corrosion by acids, alkalis and various salts. Based on the various performance advantages of raw materials, it is widely used in various types of containers, industrial accessories, medical supplies, toys, bottle stoppers and shields, and is also a good material for pipes, wires and cable sheaths.
High-density polyethylene can be produced by injection molding, extrusion, blow molding and other processing techniques. Round, square, and oval are the common shapes of high-density polyethylene bottles. Among them, round is more widely used, especially 45ml to 150ml. Milliliter bottle body, round bottle body has higher ability of absorbing external impact energy, which can well protect the contents. The oval shape is rarely used in pharmaceutical packaging, and is mainly used in cosmetic packaging. The square shape appears a little later, and it is characterized by convenient handling and saving space during transportation.
At present, the application of high-density polyethylene bottles in medicines is still mainly round and square, and various processing techniques are constantly improving with the changes in market demand. It is believed that the shape and performance of high-density polyethylene bottles will also be improved in the future. More abundant.
