How to Identify and Eliminate Gel Formation in Blown Film?
Gel” is an unwanted hard spot that appears on the surface of the film. It is generally a small, transparent or slightly discolored particle that appears to be stuck to the film.

Explore different types of screws used in blown film extrusion, including single-flight, barrier, maddock, venting screw, and grooved feed screws.
In the blown film extrusion process, both barrier screws and grooved barrels are designed to improve efficiency, throughput, and film quality.
The pancake or stacked die system is an advanced technique in blown film extrusion used to produce high-quality, multi-layer barrier films.
Thermal properties are also used a lot in blown film extrusion; we will discuss further how thermal properties are used in blown film extrusion.
Blown film extrusion is a process that is very popular and used these days in packaging, agriculture, and medical industries.
Both Nylon and EVOH materials play an important role in the packaging industry, with their own strengths and limitations.
In blown film extrusion, scanners are devices that measure and control the thickness of the plastic film. These machines rotate or oscillate around the film bubble and check the thickness at each point.
Plastic materials used in extrusion, their properties, applications, and benefits. Learn how LDPE, HDPE, PP, PVC, and other polymers impact the extrusion process.
Mechanical properties like elongation and stiffness are crucial. They determine the film’s usability, durability, and suitability for specific applications.
Corona treatment is a surface modification technique used to enhance the surface energy of films produced through blown film extrusion.
MFI stands for Melt Flow Index (MFI).It’s a simple way to measure how easily a plastic melts and flows.The Melt Flow Index, also known as Melt Flow Rate (MFR).
