History and Milestones
EEK’s journey began over 30 years ago, rooted in a vision to revolutionize capsule manufacturing in China. Founded during a period of rapid industrialization, the company quickly distinguished itself through its dedication to innovation and adherence to international quality benchmarks.
Early milestones included the establishment of state-of-the-art production facilities in Zhejiang Province, equipped with advanced machinery to ensure uniformity in every batch. By the late 1990s, EEK had expanded its portfolio beyond gelatin capsules to include HPMC—a plant-based alternative catering to vegetarian and vegan markets—and later, Pullulan capsules, derived from natural fermentation.
Commitment to Quality
Quality is the bedrock of EEK’s operations. The company’s manufacturing facilities adhere to GMP and are regularly audited by global regulatory bodies. In addition to ISO 9001, EEK holds certifications for ISO 22000 (food safety management) and Halal and Kosher approvals, reflecting its adaptability to diverse market requirements.
The in-house Quality Assurance team employs cutting-edge analytical tools, including high-performance liquid chromatography (HPLC) and Fourier-transform infrared spectroscopy (FTIR), to validate raw materials and finished products. Furthermore, EEK’s “Zero Defect” initiative integrates real-time monitoring systems across production lines, minimizing deviations and ensuring batch-to-batch consistency.
Clientele and Industry Partnerships
Over the years, EEK has forged long-term partnerships with top-tier pharmaceutical and nutraceutical companies. These collaborations are built on mutual trust, with EEK providing tailored solutions such as custom capsule sizes, imprinting services, and delayed-release coatings. In the nutraceutical sector, EEK supplies capsules to global brands like GNC and Nature’s Bounty, supporting product lines ranging from multivitamins to specialized supplements.
Global Distribution Network
EEK’s logistical prowess is a key differentiator in the competitive capsule market. Strategically located temperature-controlled warehouses in the USA (New Jersey), Europe (Rotterdam), Canada (Toronto), and Australia (Sydney) ensure that products maintain integrity during transit. These hubs are equipped with climate monitoring systems, maintaining humidity levels between 40-60% and temperatures at 15-25°C, critical for preventing capsule brittleness or deformation.
