Film blowing LDPE die heads are often used to produce high-quality films.
The LDPE die head is mainly composed of feed port, flow channel, film head and positioning components, and adopts the principle of fluid mechanics under high temperature and high pressure to form a high-speed rotating flow field in the die head, so as to achieve transverse film blowing. The LDPE die head is characterized by excellent film blowing quality, high transparency, high strength and high toughness, suitable for blowing some high-quality, high transparency requirements of the film, such as food film, medical film, industrial packaging film and so on.
