Iyo biodegradable packaging mabhegi -mabhegi ekofiuye mabhegi ekurongedza anogona kudzokororwa -mabhegi ekurongedza chikafuinogadzirwa neYantai Meifeng Plastic Packaging Co.
Kune mhando nhatu huru dzebiodegradablepolymer zvinhu.Imwe ndeye polymer zvinhu zvinogadzirwa nema microorganisms, ayo anonyanya kuwanikwa ne microbial fermentation, uye anomiririra zvakanyanya polyhydroxybutyrate, ine yakanaka biodegradation zvivakwa.Nekudaro, mutengo wekugadzirisa nekugadzira wezvinhu zvakadaro wakakwira, uye haawanzo kushandiswa mukugadzirwa chaiko.Yechipiri ndeye synthetic polymer zvinhu.Parizvino, anonyanya kushandiswa ekugadzira polymer zvinhu mumusika weChinese polyvinyl doro uye polycaprolactone.Pakati pavo, polycaprolactone inoshandiswa zvakanyanya mukurongedza chikafu.Yechitatu ndeye yakasikwa polymer zvinhu.Zvakajairwa zvechisikigo zvepolymer zvinhu zvinosanganisira cellulose, starch, protein, uye chitosan sematrix zvinhu.Mushure mekushandisa kwenguva yakati rebei, zvechisikigo zvepolymer zvinhu zvinogona kuderedzwa zvakanaka uye zvisina mhedzisiro pane ekunze ecological nharaunda.chero kusvibiswa.
Biodegradablema polymers ndechimwe chezvinhu zvinonyanya kugadzirwa mumunda wekurongedza.Biodegradable polymers ane zvakanakiranzvimbo dzakakura, kushandiswazve, kuchengetedza kwezvakatipoteredza uye pasina kusvibiswa,asi ma biopolymers ane zvimwe zvinogumira maererano nekupisa kupisa, okisijeni uye mvura mhute inodzivirira zvivakwa, mutengo uye michina zvinhu.Naizvozvo, tsvakiridzo yeiyi yekurongedza zvinhu inoda kudzika kwakadzika kuvandudza hupenyu hwesherufu, kukosha kwekudya uye kuchengetedzwa kwehutachiona hwechikafu.
