Efficient Recycling Filter for Contaminated Recyclates
The BKG HiCon K-SWE-HD/RS recycling filter is a cutting-edge solution for processing highly contaminated recyclates in blown film applications. It enables seamless operation without line shutdowns, ensuring consistent quality and efficiency.
With stricter regulations and ambitious recycling targets, the demand for efficient and reliable melt filtration is greater than ever. As part of the EU Green Deal, several countries, including Denmark, Sweden, and Finland, have committed to recycling 55% of plastic packaging by 2030. This puts increasing pressure on manufacturers to integrate recyclates into production while maintaining high product quality and operational efficiency.
Overview
Producing high-quality blown film is a complex process. The film bubble is highly sensitive to changes in process conditions, with minor variations in temperature, viscosity, and especially pressure potentially compromising the final product.
Incorporating recyclates adds another layer of complexity to an already delicate process. Pressure fluctuations during screen changes, backflushing, and venting can reduce film quality or even cause line shutdowns. The BKG HiCon K-SWE-HD/RS is designed to address these challenges, providing a stable, efficient solution for blown film production.
The system ensures stable operating conditions and eliminates pressure drops, reducing the risk of film defects and production interruptions. The advanced melt pressure-controlled venting prevents air entrapments and guarantees uniform film quality – even under demanding production conditions.
Blown Film Made of Recyclates
Blown film lines operate under extreme pressures of up to 600 bar, requiring robust and intelligent design to handle such forces. The BKG HiCon K-SWE-HD/RS is a continuous backflush screen changer designed to meet the demands of high-pressure blown film applications.
This advanced system allows the use of large proportions of highly contaminated recyclates without sacrificing quality or performance. It ensures consistent pressure conditions, even under challenging processing circumstances. The melt pressure-controlled venting start gently fills the cavity after a screen change, avoiding pressure drops and maintaining optimal stability.
The compact vertical design optimizes space utilization, making it easy to integrate into existing production lines while improving operational efficiency.
With innovations in backflush technology, the HiCon K-SWE-HD/RS efficiently manages high-pressure operations, delivering excellent results while supporting environmentally friendly practices.
