Blown Film Machine Frequently Asked Questions

What is a blown film machine?

A blown film machine is used to produce plastic film through a process called blown film extrusion. This machine melts plastic resin pellets and extrudes them through a circular die, inflating the resin into a bubble shape. The bubble is then cooled and flattened to form a continuous sheet or tube of plastic film.

How does a blown film machine work?

Blown film machines operate by feeding plastic resin pellets into an extruder barrel where they are melted and forced through a circular die. Air is introduced into the center of the die to inflate the molten resin into a bubble. As the bubble expands, it is cooled by air or water to solidify the plastic film. The film is then collapsed, flattened, and wound onto rolls.

What types of plastic film can be produced with a blown film machine?

Blown film machines can produce a variety of plastic films including: LDPE (Low-Density Polyethylene) film: Commonly used for packaging applications like bags and wraps. HDPE (High-Density Polyethylene) film: Known for its strength and used in heavier duty applications such as industrial liners and sacks. LLDPE (Linear Low-Density Polyethylene) film: Offers enhanced tensile strength and puncture resistance, ideal for stretch film and agricultural films. Multi-layer films: Combining different types of resins to achieve specific properties like barrier protection or enhanced strength.
