Strength Behind Every Sack
When industries talk about plastic raffia woven sacks, they think of durability, strength, and reliable packaging solutions. But behind every strong woven sack lies an efficient extrusion process — and at the heart of that process are high-performance screws and barrels. At Kaivanya Extrusion Technik, we specialize in designing bimetallic screw and barrel systems that keep woven sack plants running at maximum efficiency, delivering consistent quality and longer life.
From Asia to America, businesses searching for a trusted plastic raffia woven sacks supplier in the USA rely on machinery powered by Kaivanya technology. Our components are the unseen heroes that make woven sacks durable, tear-resistant, and suitable for a wide range of packaging needs.

The Role of Screws & Barrels in Raffia Sack Production
Producing plastic raffia woven sacks requires precision. Consistency in filament extrusion ensures uniform weaving, while strength in the melt process guarantees tear resistance. Any compromise in screw or barrel quality can result in uneven filaments, machine breakdowns, or higher maintenance costs.
That’s why Kaivanya engineers:
- Bimetallic screws with advanced metallurgy for wear and corrosion resistance.
- Specialized coatings like PTA tungsten carbide overlays (60–70% WC) for extended life.
- Vacuum-hardened barrels that withstand high output and abrasive polymers.
- Custom screw geometries to optimize melt flow for woven sack applications.
