Small Three Layer Blown Film Machine

Overview

1.Product Introduction

Small three layer blown film machine involves one process used to make plastic film. Extruded tubular processing is most often used with polyethylene films but can be used with other polymers.The film maybe laminating film, shrink film, agricultural covering film, bags or film for textiles and clothing, and other packaging materials.

Small three layer blown film machine adopts precision extrusion and high-performance blown film molding technology, wide range of adjustment of process parameters, wide applicability of equipment, high hardness and corrosion resistance. The specially designed screw has good plasticizing quality, which helps to improve production capacity. It is suitable for blow molding plastic films such as low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), etc.

3.Product Process

Blown film is another extrusion processes used to fabricate film products. In this case the extrusion die is shaped as a circle and air pressure is used to further expand the film. After it is expanded to the desired dimensions it is cooled to solidify the polymer.

Operating a blown film line is similar to other extrusion processes in that the polymer exiting the extruder must have uniform melt temperature and pressure while also being at the proper temperature and pressure. Compared to cast films, blown films are usually run at a lower melt temperature with lower melt flow index resins.
