COP/COC材料應用領域與聚丙烯和聚乙烯相比,COP/COC這種主要用于要求玻璃般清晰產品,如作為優異的光學膜,用于手機、電腦、液晶電視等領域,COP/COC COP具有高透明、不易碎、滅菌適應性(EO、γ射線、蒸汽滅菌)、化學穩定性優良、耐酸堿、較低的蛋白質吸附性,適合用于疫苗、生物制劑包裝的西林瓶、預灌封注射器等醫用包裝,目前,我國已經成為世界疫苗生產國,在醫藥市場規模不斷擴大的大背景下,生物制劑市場也在持續增長預灌封注射器逐步取代傳統型玻璃安額、西林瓶、普通注射器,未來幾年COP/COC材料預灌封注射器將逐步取代傳統型玻璃安甑、西林瓶、普通注射器,COP/COC消耗量大、未來市場廣闊。
