From "Stranglehold" to Global Leadership: The "Golden Casing" Embodies "Made in Henan with Wisdom"

　　In the bustling workshops of Shuanghui's First Industrial Park, unassuming white pellets flow through automated equipment, stretching into resilient casings that envelop millions of sausages—PVDC film.

　　This translucent packaging, once a "stranglehold" in China's food industry, has become Shuanghui Chemical Packaging's banner of industrial leadership. From breaking foreign monopolies to self-innovated global expansion, and from single-product breakthroughs to full industrial chain development, its upgrade journey mirrors the tenacity of Chinese manufacturing.

　　01 From Monopoly to Mastery

　　PVDC film, though seemingly mundane, is critical for sausages—impacting taste, freshness, and safety. Direct contact with meat mandates oxygen/ moisture resistance, oilproof properties, and food-grade standards. Yet in the 1990s, its technology was monopolized abroad.

　　*"Imported casings cost ¥120,000/ton—like wrapping sausages in gold,"* recalled a Shuanghui executive. Despite soaring sausage demand, reliance on Japanese/American packaging tech became a bottleneck.

　　To break free, Shuanghui:

　　1996: Imported its first film production line, sending staff overseas for training.

　　Established a Packaging R&D Center and invested in Lianbang Chemical for casing tech.

　　2004: Consolidated units into the Chemical Packaging Division, now with 9 nationwide bases covering resin synthesis, film processing, printing, and more—housing the world’s largest PVDC film R&D hub.

　　02 Smart Upgrades & Standard-Setting

　　By integrating AI and automation, Shuanghui achieved:

　　50%+ hourly output rise in film production via automated feeding systems.

　　¥10M+ cost savings in printing through equipment upgrades.

　　50%+ efficiency gains in composite packaging with solvent-free adhesives.

　　With 143 patents and cutting-edge labs, it leads in green innovation—phasing out benzene/ketone inks and spearheading 8 national standards, including the PVDC film benchmark.

　　03 Full-Chain Dominance

　　Shuanghui built a closed-loop PVDC ecosystem:

　　Upstream: Resin plants secure raw materials.

　　Midstream: Global-tier production lines enable seamless film/printing/compositing.

　　Downstream: Expanded into medical/beverage packaging, breaking barriers in chilled/ambient meat distribution and ending medical film import reliance.

　　Its PVDC stretch films, aluminum wires, and casings now export to Vietnam, Indonesia, etc., with 5,000-ton annual exports, bolstering global competitiveness.

　　Epilogue: Redefining an Industry

　　Under its "Industrialization, Diversification, Globalization, Digitalization" strategy, Shuanghui’s PVDC breakthroughs exemplify how tech innovation + vertical integration can transform "import substitution" into "world-class leadership"—reshaping food packaging’s future.
