Engineered to deliver exceptional thermal stability and wear protection under severe load conditions.
In the highly demanding landscape of global industrial lubrication, the delivery mechanism of fluids has become as vital as the chemical compounds themselves. For decades, heavy rigid plastic bottles and steel drums dominated the distribution channels. However, macro-economic pressures, environmental mandates, and logistics optimization have catalyzed a paradigm shift toward flexible spouted pouches for gear oils and transmission fluids.
As a leading China Gear Oil Pouch Manufacturer, Shandong Longhai Lubrication Technology Development Co., Ltd. addresses this shifting B2B procurement paradigm. Flexible stand-up pouches present key economic advantages: up to an 85% reduction in packaging weight compared to rigid containers, a corresponding reduction in transportation-related carbon footprint, and a dramatic decrease in post-consumer waste volume.
Our manufacturing processes utilize high-barrier, multi-layered films specifically formulated to resist chemical degradation from high-viscosity gear oils containing sulfur-phosphorus extreme pressure (EP) additive packages. This prevents plasticizer migration and ensures structural integrity throughout the product lifecycle.
A trusted, high-tech enterprise integrating R&D, advanced production, and comprehensive global sales since 2009.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier high-tech enterprise integrating research and development, synthesis, high-speed automated packaging, and global distribution. For over 15 years, we have built a complete upstream-to-downstream industrial chain system designed to supply high-performance lubrication solutions.
Our proprietary brand, "Century Longhai", along with our strategic international partnership line of British "A Ba" series products, has earned a robust market reputation. From premium passenger vehicle fluids to industrial-grade gear oils (like L-CKC and L-CKD), hydraulic fluids, refrigeration oils, and specialized compressor lubricants, our portfolio delivers exceptional machinery protection. Backed by comprehensive quality insurance from the People's Insurance Company of China (PICC), our products provide absolute peace of mind.
With a state-of-the-art facility covering 131 acres and generating an annual production capacity of 200,000 tons, we leverage intelligent blending plants and an array of testing instruments within our precision QC laboratories to satisfy rigorous OEM/ODM project scopes.
Why international B2B buyers select Shandong Longhai as their strategic supply chain partner.
Our packaging facilities feature state-of-the-art metering filling machinery configured for highly viscous lubricants. This system maintains an accuracy tolerance of 1‰-2‰ while boosting filling throughput speeds by 20% to 35% over traditional systems, guaranteeing scale-up efficiency and rapid lead-time execution.
We allocate over 5% of our annual gross revenue to scientific research and formulation development. Operating in collaborative partnership with key domestic universities and material research institutes, we continuously refine oil shear stability and flexible pouch material barrier profiles.
Located in Zibo, Shandong's petrochemical manufacturing hub, we leverage direct pipeline pathways for high-quality base oils (Group II, III, and IV synthetic PAO) and packaging materials, optimizing material acquisition costs and dispatch speeds for global shipping ports.
Our quality management systems conform to the highest international industrial safety and environment compliance standards.
To ensure reliable performance across demanding industrial environments, Shandong Longhai complies with international operational protocols. We have established and maintain integrated management system protocols certified under ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ISO 45001:2018/18001 (Occupational Health & Safety System). In addition, our automated transmission lubricants hold official Mercedes-Benz OEM certifications, validating compliance with strict European mechanical shear tolerances.

Industrial manufacturing, mining, infrastructure development, and marine operations consume vast quantities of specialty fluids under severe operating conditions. Delivering gear oil in customized, site-friendly packaging helps address key challenges in equipment maintenance:
Heavy duty gear components require fluids that maintain high oil film strength under severe thermal loads. Our specialized heavy-duty industrial gear oil (complying with API GL-5, L-CKC, and L-CKD standards) mitigates surface wear and gear micro-pitting, directly extending machinery service life.
Wind farms, offshore drilling rigs, and heavy construction equipment are frequently serviced in remote, logistically challenging areas. Transporting large rigid containers is difficult, and refilling gear boxes with traditional funnels often introduces dust and moisture contamination. Our flexible gear oil pouches feature integrated spouts for clean, precise, direct-to-gearbox filling, preventing contamination in demanding field conditions.
Different regional environments demand custom formulation profiles. For example, high-humidity marine gearboxes require specialized rust-inhibiting demulsifying chemistry, while extreme-cold operations in northern regions require synthetic low-pour-point polyalphaolefins (PAO). Longhai develops tailored formulations to meet local climate and operating conditions.
