随着经济水平不断提升,居(ju)民对(dui)(dui)(dui)(dui)生(sheng)活品质要(yao)求(qiu)提升。食品包装呈现独立(li)、小份装趋势,家(jia)庭(ting)用(yong)(yong)日(ri)用(yong)(yong)塑(su)料(liao)如鞋(xie)盒(he)、整(zheng)理(li)箱、储物(wu)盒(he)、化妆品包装等(deng),都偏向透(tou)(tou)明化发(fa)展,城市(shi)居(ju)民对(dui)(dui)(dui)(dui)外卖和一(yi)次性塑(su)料(liao)餐盒(he)需(xu)求(qiu)量大幅增加(jia)(jia),同时,医(yi)(yi)用(yong)(yong)注射器(qi)、输液袋、药(yao)品包装、其他耗材需(xu)求(qiu)量同比大幅增加(jia)(jia),市(shi)场对(dui)(dui)(dui)(dui)于透(tou)(tou)明聚烯(xi)(xi)烃的(de)需(xu)求(qiu)持续(xu)快速增长,但是在高透(tou)(tou)明、化学稳(wen)定(ding)(ding)性优良、耐(nai)酸碱、低吸(xi)附(fu),低聚集等(deng)要(yao)求(qiu)高的(de)医(yi)(yi)用(yong)(yong)、电子等(deng)领域,聚烯(xi)(xi)烃还(hai)不能(neng)满(man)足要(yao)求(qiu)。透(tou)(tou)明PP应用(yong)(yong)领域聚丙烯(xi)(xi)为满(man)足医(yi)(yi)用(yong)(yong)需(xu)要(yao),需(xu)要(yao)对(dui)(dui)(dui)(dui)PP改性,添(tian)加(jia)(jia)对(dui)(dui)(dui)(dui)人体友好(hao)的(de)抗(kang)氧(yang)剂(ji),为满(man)足耐(nai)辐(fu)照灭菌,还(hai)要(yao)添(tian)加(jia)(jia)稳(wen)定(ding)(ding)剂(ji),这些助剂(ji)尽管(guan)添(tian)加(jia)(jia)量要(yao)求(qiu)严格,加(jia)(jia)的(de)非常少,但是对(dui)(dui)(dui)(dui)于血液制(zhi)品,疫苗、生(sheng)物(wu)药(yao)剂(ji)包装用(yong)(yong)西林瓶、预(yu)灌封注射器(qi)等(deng)还(hai)是要(yao)求(qiu)不添(tian)加(jia)(jia),聚烯(xi)(xi)烃溶(rong)出物(wu)相比较也比COP/COC材料(liao)高。
COP/COC材料应用领域与聚丙烯和聚乙烯相比,COP/COC这种主要用于要求玻璃般清晰产品,如作为优异的光学膜,用于手机、电脑、液晶电视等领域,COP/COC COP具有高透明、不易碎、灭菌适应性(EO、γ射线、蒸汽灭菌)、化学稳定性优良、耐酸碱、较低的蛋白质吸附性,适合用于疫苗、生物制剂包装的西林瓶、预灌封注射器等医用包装,目前,我国已经成为疫苗生产国,在医药市场规模不断扩大的大背景下,生物制剂市场也在持续增长预灌封注射器逐步取代传统型玻璃安额、西林瓶、普通注射器,未来几年COP/COC材料预灌封注射器将逐步取代传统型玻璃安甑、西林瓶、普通注射器,COP/COC消耗量大、未来市场广阔。
