Double Colors Blown Film Extrusion
Double Colors Blown Film Extrusion utilizes a film blowing machine for the production of superior-quality film by merging two colors of low-density polyethylene (LDPE) and high-density polyethylene (HDPE) through the operation of two extruders. The ABA blown film extrusion technique facilitates the integration of these two colors within the die head, resulting in a two-layer film. This technique is frequently employed in the fabrication of products such as table cover film, two-color T-shirt bags, and an array of other items. The setup consists of one extruder, two gearboxes, and two motors, along with a single mold to generate the dual-color film. Additionally, an inverter is implemented to control machine speed, enhancing energy efficiency.
