COP pre-filled syringes reliably provide accurate drug dosage and minimize pollution risks due to their compact size and portability. They are widely utilized in biological products, high-value chemical products, antithrombotic drugs, and beauty products.
As a superior alternative to borosilicate glass, Cyclic Olefin Copolymer (COP) offers high design flexibility and unbreakable features that reduce logistics costs. Chemically, COP boasts high transparency, high rigidity, and excellent heat resistance. Its low protein adsorption, absence of heavy metals/tungsten, and compatibility with sensitive drugs ensure no detachment during storage, making it the ideal solution for modern pharmaceutical packaging.
