Blow Film Extrosion Machines

Blown Film Extrusion can be used with a wide range of plastic materials, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), and polystyrene (PS). The choice of material depends on the application & the desired properties of the film.

Blown film extrusion is the most common process for production of continuous films that are used primarily for packaging.

3. ROTATING DIE BLOWN FILM MACHINES

Rotating die blown film machines represent a significant advancement in the technology of film extrusion. Unlike traditional fixed-die machines, where the die remains stationary during the extrusion process, rotating die machines incorporate a dynamic element by allowing the die to rotate. This rotational motion introduces several advantages to the film production process.

One key benefit of rotating die machines is the enhancement of film quality. By spinning the die, the flow of molten polymer is more evenly distributed, resulting in a more uniform thickness across the width of the film. This uniformity is crucial for ensuring consistent product quality & performance, particularly in applications where precise film thickness is critical, such as in food packaging or medical films.

4. PP DOWNWARD BLOWN FILM EXTRUSION PLANTS

PP downward blown film extrusion plants refer to manufacturing facilities that specialize in production of polypropylene (PP) films using a downward blown film extrusion process. This method involves melting PP resin pellets & extruding them downwards through a circular die. The extruded molten polymer is then inflated to form a bubble, which is subsequently cooled and flattened into a thin film.

These plants are equipped with machinery & equipment tailored for PP film production, catering to a wide range of applications across industries such as packaging, agriculture & construction. PP downward blown film extrusion plants play a crucial role in meeting growing demand for PP films, which are valued for their excellent properties such as high tensile strength, puncture resistance, & chemical inertness.

5. MONO-LAYER BLOWN FILM MACHINES

Mono-layer blown film machines are specialized equipment used in the production of single-layer plastic films through the blown film extrusion process. These machines are designed to melt plastic resin pellets and extrude them through a circular die, forming a continuous tube of molten polymer.

Mono-layer blown film machines are utilized across various industries for packaging, agriculture, construction & more, offering cost-effective solutions for producing plastic films with a wide range of properties and applications. These machines consist of several components, including an extruder, die head, air ring, cooling unit, and winding unit. The extruder is responsible for melting the plastic resin pellets and conveying the molten polymer to the die head. The die head shapes the molten polymer into a tubular form, while the air ring introduces cool air to inflate the tube into a bubble.
