LINUO holds more than 130 registered patents covering the full spectrum of pharmaceutical glass packaging technology. Our intellectual property portfolio reflects three decades of continuous investment in materials science, manufacturing process engineering, and quality assurance systems.
LINUO's quality management systems and products are independently verified by leading national and international certification bodies. These certifications are not merely compliance checkboxes — they represent the operational standards our teams uphold every day.
LINUO's compliance program covers all major international pharmaceutical markets.
All LINUO pharmaceutical primary packaging is manufactured from Type I borosilicate glass and tested to USP <660>, EP 3.2.1, ChP 0672, and JP General Tests — the highest classification for chemical resistance and hydrolytic stability, suitable for biologics, vaccines, and sensitive parenteral drugs.
LINUO holds 5 active FDA Drug Master File (DMF) registrations — one for each major product category. Pharmaceutical manufacturers can reference LINUO's DMF in their own FDA submissions without disclosing confidential manufacturing information.
LINUO holds a comprehensive portfolio of quality, regulatory, and environmental certifications — covering pharmaceutical manufacturing, medical device production, laboratory accreditation, and environmental management. View the full certificate gallery on our About Us — Honors page.
