What SUNUP does

Shandong Bihai Packaging Materials Co., Ltd. (operating as SUNUP/碧海), founded in 1985 and headquartered in Junan Economic Development Zone, Shandong Province, China, designs and manufactures aseptic carton filling machines and paper-aluminum-plastic composite liquid-food aseptic packaging materials. The product portfolio spans high-speed filling lines (BH24000 at 24,000 packages/hour, BH9000, BH7500, BH7000 flexible line, BH6000, BHWDI roof-type, BHSJ12000 triangle, BHZ9000 pillow), auxiliary equipment (direct-spray and tubular sterilizers, CIP systems, aseptic tanks, straw/cap attaching machines, GDL dosing units), and roll-stock packaging materials. Technology differentiators include the BH7500's SGS-certified log7 aseptic challenge verification (a domestic first), modular 30-minute mold changeover on the BH7000 line, and a portfolio of 60+ patents covering filling and material innovations. BiHai participates as a key drafter of national standard GB/T 18706-2025 for liquid-food aseptic paper-based composite packaging materials.

The company operates a vertically integrated, capital-intensive manufacturing model: a 226-acre site with 3.6 billion RMB in fixed assets supports annual capacity of 200+ filling machines and 9 billion packaging units. BiHai was acquired on 2018-04-12 by Shenzhen-listed Kunshan Xinlai Clean Application Materials Co., Ltd. (SSE: 300260), with operations, name, and personnel preserved post-acquisition and SAP deployed for financial and operational control. The company generates revenue through two streams: capital-equipment sales (B2B enterprise deals, pricing not publicly disclosed, customized quotes per line) and recurring consumable sales of aseptic packaging materials to the same installed base — a classic razor-and-blade dynamic. Distribution is direct to enterprise customers in China and via exports to 40+ countries, supported by industry-association memberships and event-led demand generation.

Named customers include China's largest dairy and beverage companies — Yili (伊利), Mengniu (蒙牛), Sanyuan (三元), Wondersun (完达山), New Hope Liuhe (新希望), Modern Dairy (现代牧业), Coca-Cola (可口可乐), PepsiCo (百事), Master Kong (康师傅), and Huiyuan (汇源) — and the firm holds MIIT "Specialized, Refined, and New Little Giant" designation, multiple China Dairy Industry Association Science & Technology Progress First Prizes, China Light Industry Top 50 equipment manufacturer recognition, and an EcoVadis sustainability medal. The 2025-03 TPM consulting partnership with Yili Group marks a deepening from equipment vendor toward embedded operational-services supplier, consistent with the company's positioning as a domestic import-substitution alternative to Tetra Pak and SIG in Chinese liquid-food packaging.
