Film Co-extrusion Line

TPU raw materials with different temperature and hardness ranges are extruded by two or three extruders at one time.

A film co-extrusion line is a manufacturing system that combines two or more polymer materials using multiple extruders and a shared die, producing multilayer films in a single process. Each layer can impart specific properties such as strength, flexibility, barrier protection, heat resistance, or sealability. Film co-extrusion lines are widely used in the production of packaging and functional films for a variety of industrial applications.

Working principle of a film co-extrusion line

A film co-extrusion line combines two or more different polymer materials through separate extruders, feeding them into a co-extrusion die to form a multilayer film. Each extruder melts and plasticises its designated raw material under controlled temperature and pressure conditions. The molten polymers are then brought together within the die, where they are distributed into individual layers and bonded to form a unified film structure.

After leaving the die, the multilayer film passes through a cooling system to stabilise its shape and thickness. Depending on the production process, the film may undergo stretching, thickness measurement, edge trimming and other finishing operations before being pulled and wound into rolls. By precisely controlling the material ratios, extrusion temperatures, output rates and cooling conditions, a film co-extrusion line can produce films with different functional layers that improve properties such as mechanical strength, barrier performance, flexibility, heat-sealing capability and moisture resistance. This technology is widely used in food and industrial packaging, agricultural films and medical packaging, as well as other applications requiring customised film performance.

TPU High-low Temperature、High-elastic Film Co-extrusion Line Features

TPU raw materials with different temperature and hardness ranges are extruded by two or three extruders at one time.

Compared with the traditional composite process, it is more economical, more environmentally friendly and more efficient to recombine high-temperature and low-temperature thin films offline.

Products are widely used in water-proof strips, shoes, clothing, bags, stationery, sports goods and so on.
