Purge Compound Solutions for Blown and Cast Film
In blown and cast film operations, unique equipment and processing conditions have historically limited the effectiveness of conventional purge solutions. Today, tailored technologies from Bajaj address these challenges with targeted, high-performance solutions.
Blown Film: Maintaining the Bubble and Closed Loop Recycling
For blown film processors, maintaining bubble stability during purging is often critical. A collapsed bubble may potentially result in significant downtime, labor, and lost productivity due to the need for restringing. Traditionally, most purge compounds require the bubble to collapse, limiting their practicality in these operations.
Plast Purging Compound was specifically developed to overcome this challenge. Unlike traditional purge compounds, Plast Purge functions as a purging additive, blended with production resin at a masterbatch-like ratio. This allows for precise dosing through standard gravimetric/volumetric blending systems, making implementation simple and efficient.
The key advantage of Plast Purging Compound is its ability to effectively clean the extruder and die while maintaining the bubble, significantly reducing downtime and labor requirements. Both lab and field results have shown that Plast Purging Compound can reduce downtime by an average of 75% compared to purging with production resin. In addition, Plast Purging Compound can be recycled in a closed loop process, meaning no waste is generated in the purging process.

High-Power Cleaning: Plast Purge Ultra
For processors seeking a more aggressive, ready-to-use purge compound, Plast Purge Ultra provides a powerful alternative. This product is ideal for removing stubborn carbon buildup and heavy color contamination. Companies have achieved reductions of up to 80% in downtime and scrap with Plast Purge Ultra.
While Plast Purge Ultra is not suitable for closed-loop recycling, it delivers exceptional cleaning performance, often eliminating the need for manual die disassembly. In many cases, a single purge cycle is sufficient to remove significant color and carbon buildup.
For operations implementing a preventive maintenance program, regular use of Plast Purge Ultra can help prevent carbon accumulation altogether, reducing or even eliminating manual cleaning requirements of the die. In addition, depending on the film and equipment, in many scenarios the bubble can be maintained while purging with Plast Purge Ultra.
Cast Film Applications:Plast Purge Ultra
Cast film processors have their own unique demands, and Plast Purge Ultra was engineered specifically to meet them. Plast Purge Ultra is ready-to-use purge compound that processes similarly to standard production resins, ensuring ease of use without operational disruption.
Plast Purge Ultra is a low-residue formulation, meaning there is no need to “purge out the purge compound.” It effectively cleans both the extruder and die while minimizing scrap and downtime during color changes. When used regularly, it also helps prevent carbon buildup, supporting consistent product quality and improved operational efficiency.
