Mafungiro akachinja ekuchengetedza mhuka dzinovaraidza kubva pakutenga chikafu chemhuka kusvika pakubikira munhu aburitsa nzira nyowani muindasitiri yechikafu chemhuka.Zvichienzaniswa nechikafu chakaoma, chikafu chitsva chine maitiro mashoma ekugadzirisa uye yakawanda yakasvibira uye yepakutanga, iyo inowirirana nemafungiro ezvino ekushandiswa kwevachengeti vemhuka mukutsvaga kudya kwakanaka.Kunyangwe nhoroondo yebudiriro muChina isina kureba, kugona kwayo kwemusika hakugone kushoreswa nekuti chikafu chitsva chemhuka chinoenderana nemaitiro ekushandisa.

Iyo 2020 chena bepa rekushandisa mushumo weChina indasitiri yezvipfuyo inoratidza, yakakanganiswa neCCIDID19, 34.1% yevachengeti vemhuka vaizochengeta chikafu chemhuka nguva nenguva, uye 22.7% yevachengeti vezvipfuyo vaitarisa pasherufu yehupenyu hwechipfuyo.Naizvozvo, hutsva uye hupenyu hwesherufu hwechikafu chemhuka zvinhu zviviri zvakakosha kukanganisa sarudzo dzevatengi.Chikafu chipfuwo chine hunyoro hwepamusoro chinoita zvirinani mukunhuwa, kuravira, kuomerwa kwekunyura uye kukosha kwekudya.Iko kutsva kwechikafu chakaputirwa kunonyanya kuenderana neiyo oxygen transmittance ratio (OTR) yekurongedza.Xiamen Changsu's inoshanda firimu, Supamidseries zvigadzirwa - EHA firimu, ukobvu i15 μm chete.uye OTR yayo inodzorwa pazasi 2cc / (㎡.
