Impembelelo ye-Pe Material kwi-Packaging Bag Materials

Ukuthandwa kwezinto eziluhlaza ze-PE kwingxowa yokupakisha imathiriyeli ekrwada!Imathiriyeli ekrwada ye-PE iyimfuneko ekupakisheni.Ukuba ufuna ukutywina iingxowa zokupakisha, i-PE kufuneka yongezwe kwizinto eziluhlaza.Kuyacaca ukuba izixhobo ze-PE zingundoqo!Ukuthandwa kwezinto eziluhlaza ze-PE ekupakisheni:

1. Inkcazo yeempawu ze-PE ngokubanzi:

Ngokubanzi, inkangeleko yengxowa yokupakisha ye-PE ekrwada icace ngokupheleleyo, kodwa inenkungu;ithambile xa uyibamba kwaye ine-ductility elungileyo;ukumelana nobushushu obuphantsi kunye nokuxhathisa okunamandla kwamanzi, kodwa xa kuthelekiswa ne-O2, izinga lokuthintela igesi liphantsi;Okanye uyisombulule, unokushicilela itekhnoloji engwevu ekhanyayo, ayikhuthazwa kwipakethe enkulu yoshicilelo lwekofu emnyama.

2. Ulwahlulo lwemathiriyeli ekrwada eqhelekileyo yeengxowa zokupakisha ze-PE kwipakethe yangaphandle:

Inkqubo yokuvelisa i-PE, i-PE inokwahlulwa ibe ngamacandelo amathathu: HDPE.I-HDPE inoxinano oluphantsi, i-LDPE inoxinano oluphantsi, uxinaniso olunxulumene nomgca lusezantsi, kwaye i-LLDPE iphantsi.Ukusetyenziswa kwabo kugxininise kwiingxowa zokupakisha zihlukile, kwaye iimpawu zabo nazo zihluke.I-HDPE ekrwada inoxinaniso oluphezulu lwesalamane, ekwabizwa ngokuba yi-low-voltage high-voltage polyethylene, kwaye inokumelana nobushushu obuphezulu, ukumelana nobushushu, ukuxhathisa kweasidi kunye nealkali kunye nezinye iimpawu.umaleko ocacileyo.

Imathiriyeli ekrwada ye-LDPE enoxinano oluphantsi kakhulu ikwabizwa ngokuba yi-polyethylene, eyimathiriyeli ekrwada ye-PE ethambileyo.I-cocoa inokusetyenziswa ngokuthe ngqo njengeengxowa zokupakisha, ezifana neengxowa zokuthutha iziqhamo ezitsha, inyama kunye namanye amashishini okutya efriji.Okanye izikhwama zeplastiki, iibhagi zefilimu, njl. Ukuthenga ukutya.

Izinto ze-LLDPE ekrwada ezinoxinano oluphantsi lomgca: ziyafana ngenkangeleko ye-LDPE, i-ductility yobushushu obuphantsi, ukuxhathisa impembelelo, ukumelana nokuqhekeka kwentsimi yoxinzelelo, ukumelana nokudinwa, olu phawu luhle kakhulu.Sebenzisa i-ayisikrimu ye-LLDPE yoqobo, i-ayisikrimu, iibhola zenyama, amadombolo aqandusele ngokukhawuleza kunye nezinye iingxowa zokupakisha, kwaye usebenzise umaleko wokungena kobushushu bezinto ezikrwada ze-LLDPE.

3. Iindlela ezahlukeneyo zokupakisha iibhegi ezinoxinano oluphezulu lwemathiriyeli ekrwada ye-PE kunye noxinzelelo oluphantsi lwePE:

1. Ukuba isandla sibuthathaka, sinokuthamba, kwaye izinto ezixineneyo zithambile.

2. Xa ukrwela into ekrwada ngozipho, akulula ukushiya imikrwelo.Yimathiriyeli ekrwada ye-HDPE, i-HDPE enoxinano oluphezulu, kunye ne-LDPE enoxinano oluphantsi.
