Nzira yekusarudza sei bhegi zvinhu?

Kutanga, aluminium foil zvinhu
Aluminium foil iyi zvinhu zvekurongedza bhegi inovharira kuita kwemhepo, yakakwirira tembiricha kuramba (121 ℃), yakadzika tembiricha kuramba (-50 ℃), mafuta kuramba. Chinangwa chealuminium foil bag chakasiyana nebhegi rakajairwa, rinonyanya kushandiswa kupisa tembiricha yekubika uye kuchengetedza yakaderera tembiricha chikafu. Asi aluminium foil yekurongedza bhegi nekuda kweiyo zvinhu haina kusimba, iri nyore kuputsika, yakasanganiswa nekushomeka kweasidhi kuramba, hapana kupisa chisimbiso. Naizvozvo, inowanzo shandiswa chete sechinhu chepakati chebhegi, senge bhegi redu rekunwa mukaka rekurongedza, bhegi rechando rekurongedza chikafu, rinoshandisa aluminium foil.
chechipiri, PET zvinhu
PET inonziwo bidirectional stretch polyester firimu, iyi zvinhu zvekurongedza bhegi pachena zvakanaka, kupenya kwakasimba, kusimba uye kuoma kuri nani pane zvimwe zvinhu, hazvisi nyore kupaza, uye isiri-chepfu isinganakidze, kuchengetedzwa kwepamusoro, inogona kushandiswa zvakananga kurongedza chikafu. Naizvozvo, PET isiri-chepfu uye aseptic yekurongedza zvinhu zvemarudzi ese echikafu nemushonga muhupenyu hwezuva nezuva. Asi zvipingamupinyi zvayo zviri pachena, izvo hazvisi kupisa, alkali resistant, haigoni kuiswa mumvura inopisa inopisa.
Naironi yechitatu
Nylon inodaidzwa zvakare kuti polyamide, zvinhu zvakare zviri pachena, uye kupisa kupisa, kuramba kwemafuta, kushomeka kwepuncture, kupfava kukubata, asi kusingamirire kunyoro, uye kupisa kuvharika kwakashata. Saka mabhegi ekurongedza naironi anoshandiswa kurongedza chikafu chakasimba, pamwe nezvimwe zvigadzirwa zvenyama uye chikafu chekubikisa, sehuku, dhadha, mbabvu nezvimwe zvinorongedzerwa, zvinogona kuwedzera hupenyu hwesherufu yechikafu.
Yechina OPP zvinhu
OPP, inonziwo oriented polypropylene, ndiyo inonyanya kujeka yekurongedza zvinhu, zvakare ndiyo yakanyanya brittle, kushushikana zvakare kudiki. Mazhinji emabhegi ekurongedza akajeka anoshandiswa muhupenyu hwedu anogadzirwa nezvinhu zve opp, izvo zvinoshandiswa zvakanyanya mukupfeka, chikafu, kudhinda, zvizoro, kudhinda, mapepa uye mamwe maindasitiri.
Yechishanu HDPE zvinhu
Zita rakazara reHDPE ndiro polyethylene yakakwira density.
Bhegi rakagadzirwa nechinhu ichi rinonziwo PO bag. Iyo tembiricha yemhando yebhegi yakakura kwazvo. Muhupenyu hwezuva nezuva, inoshandiswa kurongedza chikafu, mabhegi ekutenga grocery, anogona zvakare kugadzirwa kuita akaumbwa firimu, rinoshandiswa chikafu chinopesana nekupinda uye insulation yekurongedza firimu.
Yechitanhatu CPP: Kujeka kwechinhu ichi kwakanaka kwazvo, kuomarara kwakakwira kupfuura PE firimu. Uye ine marudzi mazhinji uye akasiyana-siyana ekushandisa, anogona kushandiswa kurongedza chikafu, zvihwitsi kurongedza, kurongedza mishonga uye zvichingodaro. Inogona zvakare kushandiswa seyakadzika firimu rezvakasanganiswa zvinhu, izvo zvinogona kugadzirwa mumabhegi akaumbwa pamwe nemamwe mafirimu, akadai sekuzadza kupisa, bhegi rekubika, aseptic packaging, nezvimwe.
Zvinhu zvitanhatu zviri pamusoro zvinowanzoshandiswa mumabhegi ekurongedza. Hunhu hwechinhu chimwe nechimwe hwakasiyana, uye maitiro ekuita uye mashandisirwo emabhegi akaitwa akasiyana. Tinofanira kusarudza maererano nemamiriro edu ezvinhu chaiwo.
