Online InquiryA double screw co-extrusion blowing machine is a type of equipment used in package production lines that can produce multi-layered plastic film packaging. The machine consists of two parallel screws that are used to melt and extrude plastic material through a die. The screws are designed to work together in a co-rotating or counter-rotating manner to ensure efficient melting and mixing of the plastic materials.
The film blowing extruder is equipped with a multi-layer die head, which allows for the simultaneous extrusion of two plastic materials. The die head can be designed to produce a variety of packaging types, including films, sheets, bags, and pouches. The layers of plastic material can be of different types, colors, and thicknesses, depending on the specific packaging requirements.
The blown film machine has a variety of features that make it ideal for packaging production lines and also machine is able to produce shrinkable film. It is capable of producing high-quality packaging with consistent thickness and high strength. It is also highly efficient, with a fast production rate and low energy consumption,and a user-friendly interface and advanced control systems that ensure precise control of the extrusion process.
Our double screw co-extrusion plastic film blowing machine is easy to operate, energy-efficient, and capable of producing films with high optical clarity and mechanical strength. It is able to handle a wide range of plastic materials, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE).
With a reliable PE film extruder, our machine can meet customers’ production goals with ease and produce high-quality plastic films that meet their customers' expectations.
