ValuePack: Combining homogeneity and recycling

At the trade fair in Istanbul, BB Engineering will introduce its new, patented ValuePack spin pack. ValuePack combines a filter candle and a sand chamber within one housing to create a two-step filtration process. First, the melt passes through the filter candle, where it is optimally filtered over a large surface area down to 15 µm. It then flows through the sand chamber, where homogenization and shearing are the primary processes.

This reflects the established split in practical use between recycling applications and homogeneity-focused processes. According to the company, the combination of filter candle and sand pack results in significantly better homogeneity in terms of temperature and viscosity, improved spinning performance and higher yarn quality for a wide range of applications beyond pure recycling. Another advantage is the forced sealing, which works independently of pressure. This prevents leaks that can occur with self-sealing packs and provides a wider process window. Existing systems can be easily retrofitted to accommodate the slightly longer ValuePack.

VarioFil firmly established in the Turkish market

Another key focus at the joint booth with Barmag and Tekstil Servis in Hall 7, Booth 702B, is the compact spinning system VarioFil. The system is designed for a compact footprint, flexibility and consistently high yarn quality. With more than 60 systems installed since its market launch, Turkey is the largest market for VarioFil.

VarioFil produces high-quality yarns (POY, FDY, HTY, LSY, HMY) from all common polymers with a production capacity of up to 450 kg per hour and extruder. It also spins recycled PET or bottle flakes directly into POY or FDY.

Cobra filter for high contamination levels

The recycling portfolio also includes the Cobra filter, which BB Engineering first introduced at the Plastics Recycling Show Europe and at K 2025. The system combines continuous, large-area filtration with automated, chemical-free intermediate cleaning. Two filter cartridges with automatic switching ensure stable, reliable and uninterrupted operation, even at high contamination levels where conventional candle filters or screen changers reach their limits.

The integrated cleaning system significantly extends the service life of the filter media while reducing operational effort, melt loss and energy consumption - all without the use of chemicals. As a versatile solution, cobra is suitable for both coarse and fine filtration. In addition to PET recycling, the system is also suitable for other applications, such as plastic spinning, where it can be used to improve efficiency or be retrofitted into existing lines.
