Ukuthelekiswa kweentlobo ezintlanu zeefilimu zecuba lomsi womsi
1) Ifilimu yePVC iyancipha
Ubunzima obuphezulu , Ngenxa yokungasebenzi kakuhle kwe-optical, ukungasebenzi ngokwaneleyo kokutywinwa kobushushu ukuze kuhlangatyezwane neemfuno zoomatshini be-charter enesantya esiphezulu, kunye nemekobume engathandekiyo, ishiywe yishishini lecuba ngaphandle kokukhuthazwa okubanzi;
2) ifilimu ye-cellophane
I-cellulose ehlaziywe ngokutsha, eyaziwa ngokuba yi-cellophane, ibonakala ngokucaca okuphezulu, ukukhazimla okulungileyo, ukuqina okuphezulu, ukuprintwa kakuhle, kwaye akukho mfuneko yonyango ngaphambi kokushicilela;Ineempawu ezichasene ne-static kwaye akulula ukufunxa uthuli.Kodwa i-cellulite ibaluleke kakhulu (i-ρ≈ 1.31 g / cm3), kunye ne-hydrophilicity kunye nokunganyangeki komswakama, ifilimu ixhomekeke kwi-deformation ngenxa yeqondo lokushisa kunye nokufuma, kwaye ayikwazi ukuvalelwa ngokuthe ngqo ubushushu.Inokupakishwa kuphela ngesandla kwaye ayikwazi ukuziqhelanisa noomatshini bokupakisha abanesantya esiphezulu.Ngaphezu koko, ukusetyenziswa kwe-cellophane kwipakethe ye-cigarette inexabiso eliphezulu leyunithi, elithe layitshintsha ngokuthe ngcembe;
3) iPolyvinylidine chloride (PVDC)
Ifilimu yecuba egqunyiweyo inomsebenzi obalaseleyo wokutywinwa kobushushu obuphantsi (ubushushu bokuvalwa kobushushu yi-107 ℃ ~ 140 ℃), kunye ne-coefficient ye-friction ngexesha lenkqubo yokupakisha ingaphantsi kwe-0.3, ebonisa ukusebenza kakuhle kwe-anti-static.
4) Ifilimu yomsi yeBOPP
Ineempawu ezingenakulinganiswa ezifana nenkungu ephantsi, iglosi ephezulu, uluhlu olubanzi lokutywinwa kobushushu, amandla okutywinwa kobushushu obuphezulu, amandla abalaseleyo okuthintela umphunga wamanzi, ubukhulu obufanayo, uluhlu olubanzi lokulawula ukushwabana, ukuqina okuphezulu, kunye nobuhlobo bendalo, ngokuthe ngcembe ibe yeyona nto iphambili yokupakisha ifilimu. yecuba.
5) Ifilimu yeBOPLA kunye nefilimu yePLA
I-BOPLA imele iPolylactic Acid.Yenziwe ngemithombo ehlaziyekayo efana nestatshi sombona okanye umoba, yipolymer yendalo eyilelwe ukufaka endaweni yeeplastiki ezisekwe kwipetroleum esetyenziswa ngokubanzi njengePET (ipolyethene terephthalate).Kwishishini lokupakisha, i-PLA ihlala isetyenziselwa iingxowa zeplastiki kunye nezitya zokutya.
Ukwamkela itekhnoloji yokupakisha ephezulu kunye neendlela
Ukuze kwandiswe ubomi beshelufu yokutya, ubuchwephesha bokupakisha obutsha buye baphuhliswa ngokuqhubekayo, njengokupakisha okusebenzayo, ukupakisha okuchasene nokungunda, ukupakishwa kobungqina bokufuma, ukupakisha okuchasene nenkungu, ukupakishwa kwe-anti-static, ukupakishwa okukhethiweyo okuphefumlayo, ukupakisha okuchasene nokutyibilika, i-buffer. ukupakishwa, njl. Ezi teknoloji zitsha zisetyenziswe ngokubanzi kumazwe athuthukileyo, kodwa azisetyenziswanga kakhulu e-China, kwaye ezinye iindlela zisabhalwa.Ukusetyenziswa kwezi teknoloji eziphambili kunokuphucula kakhulu umsebenzi wokukhusela wokupakisha.
Khetha oomatshini bokupakisha kunye nezixhobo ezihambelana nobuchwepheshe bokwenza ukutya
Ukuhlangabezana neemfuno zetekhnoloji yokulungisa ukutya, kuye kwaphuhliswa izixhobo ezitsha zokupakisha, ezinje ngoomatshini bokupakisha ivacuum, oomatshini bokupakisha be-vacuum, oomatshini bokupakisha bobushushu, oomatshini bokupakisha beblister, oomatshini bokupakisha abaxhonywe ngumzimba, izixhobo zokubumba ezishushu, oomatshini bokuzalisa ulwelo. , ukwenza / ukuzalisa / ukutywina oomatshini bokupakisha, ukupakisha okungenazintsholongwane iiseti ezipheleleyo zezixhobo, njl. Ukukhetha okanye ukuyila oomatshini bokupakisha ohambelana neteknoloji yokulungisa ukutya kunye nomthamo wokuvelisa ngokusekelwe kwizinto ezikhethiweyo zokupakisha kunye neendlela zokupakisha kukuqinisekisa ukupakishwa okuphumelelayo.
Ukwazisa ngeBrand kuyilo lokuhombisa lokupakisha kunye noyilo lokupakisha
Ukupakishwa kunye noyilo lokuhombisa kufuneka luhambelane nezinto ezikhethwayo kunye nemikhwa yabathengi kunye nabathengi kwilizwe elithumela ngaphandle.Kungcono ukulungelelanisa uyilo lwepateni kunye nengaphakathi.Uphawu lokuthengisa kufuneka lubekwe ngokubonakalayo kwaye isicatshulwa kufuneka sihambelane neemfuno zokutya.Inkcazo yemveliso kufuneka ibe yinyani.Uphawu lokuthengisa kufuneka lunomtsalane, lube lula ukuluqonda, lusasazeke lula, kwaye lunokudlala indima yokwazisa ngokubanzi.Uyilo lokupakisha lweemveliso ezidumileyo kufuneka lube nolwazi lophawu.Enye ukupakishwa kwemveliso kulula ukuyitshintsha, echaphazela ukuthengisa.Umzekelo, iviniga ye-Laoliutiao yaseTshayina inegama elihle eJapan nakumazantsi-mpuma e-Asia, kodwa umthamo wentengiso wehla kakhulu emva kokutshintsha ukupakishwa, kuba abathengi bathandabuza malunga nokupakishwa okutsha.Ke, imveliso kufuneka ipakishwe ngokwesayensi kwaye ayinakuguqulwa lula.
I-1, Iimfuno ekufuneka zihlangatyezwe kwiingxowa zokupakisha zebakala lokutya
Ukupakishwa komgangatho wokutya kufuneka kuhlangabezane neemfuno zokhuseleko zayo yonke imiba yokutya
Iimfuno zokupakishwa kokutya zinokuvala umphunga wamanzi, iigesi, amafutha, kunye nezinyibilikisi eziphilayo;
2. Ngokweemfuno ezikhethekileyo zemveliso yokwenyani, yongeza imisebenzi efana nothintelo lomhlwa, uthintelo lomhlwa, kunye nothintelo ngemitha ye-electromagnetic;
3. Qinisekisa ukhuseleko lokutya kunye nokungangcoliseki ngelixa usondiswa ubomi beshelufu yokutya.
Izinto eziphambili kunye nezincedisayo ezisetyenziselwa ukupakishwa komgangatho wokutya kufuneka zingaqulathi izinto ezinokubangela ingozi kumzimba womntu, okanye umxholo kufuneka ube phakathi koluhlu oluvumelekileyo lwemigangatho yelizwe.
Ngenxa yobume obukhethekileyo bokupakishwa kweplastiki yebakala lokutya, kuphela ngokulandela ngokungqongqo imigangatho yemveliso apho iimveliso zinokuvunywa kwaye zibekwe kwimarike.
Zonke iingxowa zokupakisha zangaphakathi ezidibana nokutya zithobela ngokungqongqo inkqubo yemveliso yeengxowa zokupakisha zebakala lokutya, ezingaqinisekisi kuphela ukhuseleko kunye nococeko, kodwa zikwaqinisekisa incasa yokuqala emnandi.
Endaweni yeengxowa zokupakisha zebakala lokutya, umahluko ophambili ekubunjweni kwezinto eziphathekayo ulele ekusebenziseni izongezo.Ukuba ii-agent zokuvula zongezwa kwizinto eziphathekayo, azikwazi ukusetyenziselwa ukupakisha ukutya.
2, Ukwahlula njani phakathi kwebakala lokutya kunye neengxowa zokupakisha ezingezizo ukutya?
Xa ufumana ibhegi yokupakisha, jonga kuqala.Izinto ezintsha kraca azinavumba, imvakalelo entle, ukuthungwa okufanayo, kunye nemibala eqaqambileyo.Kuphela ezo zihlangabezana nemigangatho zibakala lokutya kunye neengxowa ezinobume bendalo ezikhuselekileyo nezicocekileyo.
3, Ukuhlelwa kweengxowa zokupakisha ukutya
Ngokomda wesicelo sayo, inokwahlulwa ibe:
Iingxowa eziqhelekileyo zokupakisha ukutya, iingxowa zokupakisha ukutya ezifunxayo, iingxowa zokupakisha ukutya ezivuthekileyo, iingxowa zokupakisha ezibilisiweyo zokutya, iingxowa zokupakisha ezishushu, kunye neengxowa ezisebenzayo zokupakisha ukutya.
Kukho neentlobo ezininzi zezinto eziphathekayo: iingxowa zeplastiki, iingxowa ze-aluminium foil, kunye neengxowa ezidibeneyo zixhaphakile.
Iingxowa ze-vacuum zisetyenziselwa ukukhupha kunye nokutywina wonke umoya ngaphakathi kwepakethe, ukugcina imeko ecinezelekileyo kakhulu ngaphakathi kwesikhwama.Ukunqongophala komoya kufana nefuthe eliphantsi le-oksijini, okwenza kube nzima ukuba i-microorganisms iphile, ukuze kufezekiswe injongo yokutya okutsha kwaye kungabikho kwenzeka isifo kunye nokubola.
Iingxowa ze-aluminiyam ye-foil yokutya zenziwe nge-aluminiyam kunye nezinye izinto eziphezulu zokuthintela ngokudibanisa okomileyo ngokusekelwe kwiipropati ezizodwa ze-aluminium.Iingxowa ze-aluminiyam zefoyile zinokuxhathisa ukufuma okugqwesileyo, umqobo, ukuchasa ukukhanya, ukuchasana nokungena, kunye nenkangeleko entle.
Iingxowa ezidityanisiweyo zodidi lokutya zibubungqina bokufuma, ziyakwazi ukumelana nokubanda, kunye nobushushu obuphantsi bobushushu obutywinwe ngokomelela.
