Ifilimu yeplastiki njengezinto zokuprinta, iprintwa njengengxowa yokupakisha, inokukhanya nokucacileyo, ukumelana nokufuma kunye nokumelana neoksijini, ukuqina komoya okuhle, ukuqina kunye nokumelana nokugoba, umphezulu ogudileyo, inokukhusela imveliso, kwaye inokuphinda ivelise imilo yemveliso, umbala kunye nezinye izibonelelo. Ngophuhliso lweshishini le-petrochemical, iintlobo ezininzi zefilimu yeplastiki, ifilimu yeplastiki esetyenziswa rhoqo i-polyethylene (PE), i-polyvinyl chloride (PVC), i-polystyrene (PS), ifilimu ye-polyester (PET), i-polypropylene (PP), i-nylon (PA) njalo njalo. Ukongeza, kukho ezinye iintlobo ezininzi zefilimu yeplastiki, umenzi wokupakisha oguquguqukayo we-Shunfa upakisha ucinga ukuba kuyimfuneko ukuqonda iimpawu zefilimu yeplastiki ngaphambi kweengxowa zokupakisha ezenziwe ngokwezifiso. Uhluze ngokukodwa iimpawu zeentlobo ezili-11 zefilimu yeplastiki phantsi kwengxowa yokupakisha ukuze ubhekisele kuyo.
1. I-Polyvinyl chloride (PVC)
Iingenelo zefilimu yePVC kunye nePET ziyafana, kwaye ziyafana kwiimpawu zokungafihli nto, ukuphefumla, ukumelana ne-asidi kunye ne-alkali. Iingxowa zokutya ezininzi zokuqala zenziwe ngeengxowa zePVC. Nangona kunjalo, iPVC inokukhupha ii-carcinogens ngenxa yokungaphelelanga kwe-polymerization yezinye ii-monomers kwinkqubo yokwenziwa, ngoko ke ayifanelekanga ukuzalisa izinto ezikumgangatho wokutya, kwaye ezininzi ziye zatshintshela kwiingxowa zokupakisha zePET, uphawu lwezinto oluthiwa yiNombolo 3.
2. I-Polystyrene (PS)
Ukufunxwa kwamanzi kwefilimu ye-PS kuphantsi, kodwa uzinzo lwayo olunobukhulu lungcono, kwaye ingacutshungulwa ngokudubula idayisi, ukucinezela idayisi, ukukhupha kunye ne-thermoforming. Ngokubanzi, yahlulwe ngokweendidi ezimbini zokufunxa kunye nokukhupha ulwelo ngokwendlela eyenze ngayo inkqubo yokufunxa. I-Unfoamed PS isetyenziswa kakhulu kwizixhobo zokwakha, kwiithoyi, kwizinto zokubhala, njl.njl., kwaye inokwenziwa rhoqo kwizikhongozeli ezizaliswe ziimveliso zobisi ezibilisiweyo, njl.njl. Kwiminyaka yakutshanje, ikwasetyenziswa kakhulu ekwenzeni izitya ezilahlwayo, kwaye uphawu lwezinto yiNombolo 6.
3. I-Polypropylene (PP)

Uphawu olukhulu lwe-PP kukumelana nobushushu obuphezulu (malunga ne--20 ° C ~ 120 ° C), kwaye iqondo lokunyibilika liphezulu njenge-167 ° C, elifanelekileyo lokuzalisa ubisi lwesoya, ubisi lwerayisi kunye nezinye iimveliso ezifuna ukucoca ngomphunga. Ubunzima bayo buphezulu kune-PE, esetyenziselwa ukwenza izigqubuthelo zesikhongozeli, kwaye uphawu lwezinto yiNombolo 5. Ngokubanzi, i-PP inobunzima obuphezulu, kwaye umphezulu uyakhazimla ngakumbi, kwaye awuvelisi ivumba elibi xa litsha, ngelixa i-PE inevumba elinzima lekhandlela.
4. Ifilimu yePolyester (PET)
Ifilimu yePolyester (PET) yiplastiki yobunjineli ye-thermoplastic. Izinto zefilimu ezincinci ezenziwe ngephepha elingqindilili ngendlela yokukhupha kunye nokolula okubini. Ifilimu yePolyester ibonakaliswa ziimpawu ezintle zoomatshini, ukuqina okuphezulu, ubulukhuni kunye nokuqina, ukumelana nokubhoboza, ukumelana nokungqubana, ukumelana nobushushu obuphezulu nobuphantsi, ukumelana neekhemikhali, ukumelana neoyile, ukuqina komoya kunye nokugcinwa okuhle kwevumba elimnandi, yenye yezona substrates zefilimu ezidityanisiweyo ezisetyenziswa rhoqo ukumelana nokuvuleka, kodwa ukumelana ne-corona kuphantsi, ixabiso liphezulu. Ubukhulu befilimu ngokubanzi yi-0.12mm, esetyenziswa rhoqo njengezinto zangaphandle zengxowa yokupakisha ukutya, kwaye ukuprintwa kulungile. Phawula uphawu lwento 1 kwimveliso yeplastiki.
5. Inayiloni (PA)
Ifilimu yeplastiki yenylon (i-polyamide PA) okwangoku yimveliso yeentlobo ngeentlobo ezisetyenziswa kakhulu kwezoshishino, apho iintlobo eziphambili ezisetyenziselwa ukuvelisa ifilimu yinylon 6, nylon 12, nylon 66 njalo njalo. Ifilimu yenylon yifilimu eqinileyo kakhulu, ibonakala kakuhle, kwaye ikhanya kakuhle. Amandla okutsalwa, amandla okutsalwa, ukumelana nobushushu obuphezulu nobuphantsi, ukumelana neoyile, ukumelana nesinyibilikisi sendalo, ukumelana nokuguguleka kunye nokumelana nokubhoboza zilungile kakhulu, kwaye ifilimu ithambile, ukumelana neoksijini okuhle kakhulu, kodwa umqobo womphunga wamanzi awulunganga, ukufunxwa komswakama, ukungena komswakama kukhulu, kwaye ukuvalwa kobushushu akulunganga. Ifanelekile ukupakisha izinto eziqinileyo, njengokutya okunamafutha, ukutya okuqhotsiweyo, ukutya okufakwe nge-vacuum, ukutya okuphekayo, njl.
6. I-Polyethylene enoxinano oluphezulu (i-HDPE)
Ifilimu ye-HDPE ibizwa ngokuba yi-geomembrane okanye ifilimu engangeni manzi. Indawo yayo yokunyibilika imalunga ne-110℃-130℃, kwaye uxinano lwayo luyi-0.918-0.965kg/cm3. Yi-crystallinity ephezulu, i-non-polar thermoplastic resin, imbonakalo yokuqala ye-HDPE imhlophe njengobisi, kwindawo encinci enqamlezileyo yenqanaba elithile lokukhanya. Inokumelana okuhle kumaqondo obushushu aphezulu naphantsi kwaye iyamelana nempembelelo, nokuba kumaqondo obushushu aphantsi angama-40F. Uzinzo lwayo lweekhemikhali, ukuqina, ukuqina, amandla oomatshini, amandla okukrazula zilungile kakhulu, kwaye ngokwanda koxinano, iimpawu zoomatshini, iimpawu zokuthintela, amandla okutsalwa kunye nokumelana nobushushu kuya kuphuculwa ngokufanelekileyo, inokumelana ne-asidi, i-alkali, izinyibilikisi zendalo kunye nokunye ukubola. Ukuchongwa: ikakhulu ayibonakali, ivakala njenge-wax, ukukhuhla okanye ukukhuhla kwingxowa yeplastiki xa irhashaza.
7. I-Polyethylene enoxinano oluphantsi (LDPE)
Uxinano lwefilimu ye-LDPE luphantsi, luthambile, lunokumelana nobushushu obuphantsi, ukumelana nempembelelo kuzinzo lweekhemikhali kulungile, phantsi kweemeko eziqhelekileyo i-asidi (ngaphandle kwe-asidi enamandla e-oxidizing), i-alkali, ukubola kwetyuwa, kunye nokufakelwa kombane okuhle. I-LDPE isetyenziswa kakhulu kwiingxowa zeplastiki, uphawu lwezinto ezisetyenzisiweyo luyiNombolo 4, kwaye iimveliso zayo zisetyenziswa kakhulu kubunjineli bokwakha kunye namacandelo ezolimo, njenge-geomemofilm, ifilimu yezolimo (ifilimu yeshedi, ifilimu ye-mulch, ifilimu yokugcina, njl.njl.). Ukuchongwa: Ingxowa yeplastiki eyenziwe nge-LDPE ithambile, ayirhawuzeleli kangako xa ixovwa, ifilimu yeplastiki yokupakisha yangaphandle ithambile kwaye kulula ukuyikrazula i-LDPE, kwaye ifilimu ye-PVC okanye ye-PP ebuthathaka kwaye iqinileyo.
8. I-Polyvinyl Alcohol (PVA)
Ifilimu edityanisiweyo yePolyvinyl alcohol (PVA) yifilimu eneempawu eziphezulu zokuthintela ezenziwe ngokugquma ulwelo olunyibilikayo emanzini oluguquliweyo lwe-polyvinyl alcohol kwisiseko seplastiki ye-polyethylene. Ngenxa yokuba ifilimu edityanisiweyo ye-polyvinyl alcohol eneempawu ezilungileyo zokuthintela kwaye ihlangabezana neemfuno zokhuseleko lokusingqongileyo, amathuba emarike yale mpahla yokupakisha aqaqambile kakhulu, kwaye kukho indawo ebanzi yemarike kwishishini lokutya.
