Shanghai Daoqin Plastics Co., Ltd.

most new new 冠状病毒愈演愈烈, upper various 口罩鱼龙 mixed 杂, large remove to 口罩会困惑 outer, how to selection combined 适 口罩也 need attention/notes.

因 is product type more, true positive has 效进行 medical grade grade 别 口罩却不 more, therefore according to different standards, classification 也不一样. from 材质 看, main/primary separation is 纱布口罩, 无纺布口罩 and PTFE nano film 口罩; from function upper separation, also can separation is medical grade outer 科口罩, one-time property medical grade and medical grade anti 护口罩 and other. main/primary analysis 口罩灭菌 for outer packaging requirements, and packaging for market amount effect/influence.

口罩 灭菌 methods

generally medical devices main/primary methods is high temperature 蒸汽, ring oxygen 乙烷, 辐射灭菌, low temperature and other pellets, 而我们 medical grade 口罩则 using/adopting its in ring oxygen 乙烷灭菌 methods 进行杀菌处理（俗称EO灭菌）. 而人们通俗认知 臭 oxygen 杀菌, outer 线杀菌 for medical grade function large, therefore that 打 紫 outer 线杀菌 achieve 口罩循 ring utilizing equipment or device upper has function.

currently market upper has 一 尝试 using/adopting 辐射灭菌, is is product and process property, 辐射灭菌 rear generate gas, and 熔喷材 material rear add fast molecular weight fracture, aging can to anti function.

in addition production rear 口罩进行灭菌 rear in 运输储存 process in is 无菌状态, use methods micro material, medical devices 无菌不 is for, is micro material active decrease/reduce to most low 状态, currently medical devices 无菌概 rate is is 10-6, 即百万 separation 之一.

meanwhile, is ring oxygen is material 质, one-time property outer 科口罩, grade medical grade and other is using/adopting ring oxygen 乙烷进行灭菌处理, how to ensure rear, in has ring oxygen 乙烷残留, can in use 时, ring oxygen can separation analysis, to analysis standards （国际 standards is analysis rear ring oxygen 乙烷 残留 amount less 于10ｕg/g）, this and packaging material gas property has very large 关系, usually packaging use polyethylene (PE) PE packaging bag analysis time non long, if as 不当, very easy let 消费者佩戴 没 has full analysis 口罩, for has 害, therefore true positive combined outer packaging bag generally using/adopting high gas property and retardant 隔 纸塑 packaging, market upper one-time property 口罩普遍 using/adopting ring oxygen 乙烷灭菌 PE plastics bag packaging, need 存放20天 above 以利于 bag inner ring oxygen analysis.  

口罩灭菌 for packaging requirements  

positive upper 面 说, ring oxygen analysis time and outer packaging gas property relatively large. below/following is types packaging comparison 图供参考.

PE polyethylene (PE) plastics bag

due to gas property relatively 差, 会导致 ring oxygen 乙烷无 method 进入口罩 internal from reduce 杀菌消毒 彻底 property, meanwhile 也会造 formed analysis 不彻底致 make ring oxygen 乙烷残留 in upper, in loss 害 身体健康. in addition, plastics bag packaging analysis time will long 达20天, in market for 口罩空 front need lower, large large effect/influence supply.  

纸塑 packaging bag

due to packaging in 纸 存 in can has reinforcement gas property, reinforcement 杀菌消毒 彻底 property reduce ring oxygen 乙烷残留 can can property. usually analysis time 7天甚至 more short, most short can 2-3天完 formed, reduce analysis cycle, retardant property excellent 越, can make maintain 无菌状态 long year above, more safety, 当然纸塑 packaging is packaging process and step/link more more, versus ratio polyethylene (PE) plastics bag, cost more high.

currently China market upper medical grade 口罩PE plastics bag packaging 占90%, bag 仅占10%, is 口罩灭菌 rear, polyethylene (PE) packaging need more long time ensure ring oxygen analysis, therefore production and market time need more long, 但纸塑 packaging decrease/reduce 口罩出厂 time, more fast speed 保护消费者健康. therefore if in packaging cost can 靠 情况 lower, using/adopting packaging can large improve/increase market amount.
