Ingxowa yokuPakisha ukutya Material Intshayelelo

Abantu abaninzi abazi ukuba yeyiphi imathiriyeliiingxowa zokupakisha ukutyazenziwe ngokubanzi.Onyanisekileyo uya kuchaza ngokufutshane izixhobo zeibhegi yokupakisha ukutyas.

Izinto zokupakisha ukutya: I-PVDC (i-polyvinylidene chloride), i-PE (i-polyethylene), i-PP (i-polypropylene), i-PA (nylon), i-EVOH (i-ethylene / i-vinyl alcohol copolymer), ifilimu ye-aluminium (i-aluminium + PE), njl., iimbumba ezininzi ezinkulu.
Ukuveliswa kwefilimu kunokwahlulwa ibe: ifilimu yolula, ifilimu evuthelweyo.
Okwangoku, izinto eziphambili ezisetyenziselwa ukupakishwa kokutya yiPP kunye ne-PE, oko kukuthi, i-polypropylene kunye neeplastiki ze-polyethylene.Kuzo zombini izixhobo, ukupakishwa kokutya kunokwaneliswa.
Xa kuthelekiswa nokupakisha okungekho ukutya, i-PP kunye ne-PE ayinazo izongezo zeplastiki.Sonke siyazi ukuba izongezo zeplastiki zinempembelelo enkulu kumzimba womntu, ngakumbi impilo yabantwana.I-PP kunye ne-PE ayiyi kukhulula izinto ezinobuthi ngexesha lokusetyenziswa.Ezinye Ezinye izinto zinokubangela umhlaza, kodwa i-PP kunye ne-PE azikwenzi.Ukupakishwa kwe-PVC kusetyenziselwa ukusetyenziselwa ifilimu yokutya, kodwa ngenxa yokungakhuseleki kwayo, ngokuthe ngcembe ithathelwe indawo yifilimu ye-PE.
Iimpawu ze-PE zezi: izinto ezithambileyo, ezinomatshini zihlwempuzekile kunePP, iimveliso ezimele zibandakanya iingxowa zokuthenga kwivenkile enkulu, ukugoqa iplastiki, iingxowa zenkunkuma, njl njl. I-PP inzima, i-anisotropic (kulula ukuyikrazula ukuba kukho i-gap), i-mechanical good mechanical iipropati, kunye nokusebenza kweqondo lokushisa eliphezulu kungcono kune-PE, oku kuthetha ukuba imveliso ineengxowa zesonka.
Ngokuqhelekileyo ngokwesakhiwo sezinto eziphathekayo, i-layer yangaphakathi yi-PE okanye i-CPP, i-layer yangaphandle yi-PA, PET, i-middle ingaba yi-EVOH okanye i-PVDC, njl., Kwaye ezinye ziyifilimu ye-aluminium okanye i-aluminium foil.

I-PE kunye ne-CPP zineempawu ezintle zokutywina ukushisa, oko kukuthi, kulula ukutywinwa.
I-PA kunye ne-PET zinokuprintwa kakuhle kwaye zinokusetyenziswa kumaleko angaphandle ukuprinta imifanekiso emihle.
I-PVDC kunye ne-EVOH zineempawu ezintle zomqobo kwaye zithintela i-oxidation.
Ifilimu ye-Aluminized kunye ne-aluminium foil ineempawu ezintle zokukhusela ukukhanya kwaye zifanelekile kwiimveliso ezingafanelekanga ukukhanya.

Izinto ezahlukeneyo zineempawu ezahlukeneyo kunye nokusetyenziswa okuhlukeneyo.Iingxowa zokupakisha ukutya ngokubanzi azikho into enye, kodwa ziyi-multi-layer composites, ezinokudityaniswa kunye nemigangatho emibini, imigangatho emithathu, imigangatho emine, njl.
Ukutya okomileyokwayeUkutya ikusemkhencenizenziwe ngokubanzi nge-PET/PE.
Umzekelo,ukupheka kobushushu obuphezuluyenziwe ngokubanzi ngeCPP ehlanganisiweyo yenayiloni, okanye ezinye iimbumba.
I-casing ebomvu ye-ham yinto enye ye-PVDC.
Iilekese kunye netshokolethingokuqhelekileyo sebenzisa iphepha elicacileyo / PP, iphepha le-kraft / PE / AL / PE, AL / PE, njl.
