Yantai Hengchang Packaging: Empowering Low-gram Weight High-strength Flexible Container Bags with Austrian Cutting-edge Equipment to Create a Global Benchmark for Cost-performance.

— leverages Starlinger (Austria) high-speed tape extrusion lines and intelligent circular looms to achieve industry-defining breakthroughs in low GSM, high-strength, and precision-engineered bulk bags. By integrating these cutting-edge technologies, we deliver cost-efficient yet ultra-reliable solutions that empower global clients to optimize packaging expenditures while maintaining stringent quality standards. The innovation-driven approach reaffirms the core competitiveness of Chinese manufacturing in the global industrial packaging arena.

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.

Hengchang Packaging leverages advanced equipment and technical expertise to optimize weaving density and the molecular structure of flat yarns. While maintaining a high load-bearing capacity of 500kg–2000kg, Hengchang’s products significantly reduce customers’ logistics costs—material costs per Bulk Bag are lowered by approximately 15%, helping global clients secure long-term benefits amid Bulk Bag procurement cost fluctuations through our unique solutions.

“Many customers once mistakenly believed lightweighting meant compromising quality, but our data proves that precision equipment and process innovation can achieve a balance of ‘lighter, stronger, and more cost-effective.’”

Hengchang’s Bulk Bags have passed multiple international certifications, with a consistent product qualification rate above 99.2% and an annual production capacity exceeding 800,000 units. Hengchang has become a long-term partner for industry leaders in chemicals, mining, food, and other sectors.

In the wave of upgrading from "Made in China" to "Intelligent Manufacturing in China," Yantai Hengchang Packaging Co., Ltd. has adopted a dual-engine model of "imported equipment + independent process innovation" to break the monopoly in the high-end bulk bag market. Through large-scale production and supply chain optimization, Hengchang transforms technological dividends of Starlinger equipment into end-product price advantages. It provides international clients with bulk bag products that match the quality of European and American high-end brands while offering prices 25%-30% lower, truly fulfilling our corporate vision of "making global logistics packaging more efficient and economical."

Yantai Hengchang Packaging Co., Ltd. has been deeply rooted in the bulk bag industry for decades, specializing in customized packaging solutions for global clients. Hengchang products are exported to over 60 countries and regions. In the future, the company will continue to drive industrial upgrading through technological innovation, empowering "Made in China" bulk bags to shine on the global stage.
