Precision-Crafted Bulk Bags: Starlinger Engineering Meets Next-Gen Sustainability

Hengchang Packaging has always regarded technological and equipment capabilities as the core of product competitiveness. The fabric for bulk bag production is manufactured using Starlinger's starEX 1600 high-speed flat tape extrusion line . Leveraging its century-long technical expertise and innovative design, this system provides a robust foundation for producing low GSM, high-strength polypropylene tapes. Integrated with a fully automated feeding system, intelligent thickness monitoring, online filtration, and high-efficiency reel change mechanisms, the equipment not only enhances tape uniformity and tensile strength but also reduces raw material waste by over 15%, ensuring a high yield rate for subsequent weaving processes.

In the circular weaving stage, Starlinger's equipment features a 1950mm ultra-wide adjustable loom frame and a multi-stage automatic warp tension control system , guaranteeing fabric surface flatness with ±5mm tolerance. This innovation fundamentally resolves the "uneven edge tension" issue common in traditional methods. Combined with a patent-pending weft auto-stop system and 180mm-long warp beam capacity, the machinery enables 72-hour continuous production with 40% fewer downtime intervals for reel changes, achieving a 30% higher daily output than industry averages. These advancements epitomize "high productivity, low energy consumption" in intelligent manufacturing.
