Amafilimu ahlanganisiwe ashisayo nabandayo

Ayini Amafilimu Ashisayo Nabandayo Ahlanganisiwe?

Amafilimu ahlanganisiwe ashisayo nabandayo angamafilimu epulasitiki anezingqimba eziningi aklanyelwe ukusebenza ngaphansi kwezinqubo zokubopha ukushisa kanye nokucindezela okuzungezile.
Ngokuvamile akhiwa ngezinto ezifana ne- PET , i-BOPP, i-PE, i-CPP, noma i-Nylon ezihlanganiswe ndawonye kusetshenziswa izinamathiselo noma i-co-extrusion.
Lawa mafilimu asetshenziswa kabanzi ekupakisheni, ekuphrinteni, e-lamination, kanye nasezinhlelweni zokufaka izinto ngenxa yokuguquguquka kwawo kokushisa kanye nobuqotho besakhiwo.

Yimuphi umehluko omkhulu phakathi kwamafilimu ahlanganisiwe ashisayo namafilimu ahlanganisiwe abandayo?

Amafilimu ahlanganisiwe ashisayo adinga ukushisa kanye nengcindezi ukuze abophe—avame ukusetshenziswa ekufakweni kwe-thermal lamination noma ekufakweni kwe-heat-seal.
Amafilimu ahlanganisiwe abandayo, ngakolunye uhlangothi, angasetshenziswa kusetshenziswa izinamathiseli ezizwela ukucindezeleka ngaphandle kokushisa, okwenza zifaneleke ekufakweni kwe-cold lamination noma ezinqubweni zokushisa okuphansi.
Amanye amafilimu ahlanganisiwe enzelwe ukusekela kokubili ukubopha okushisayo nokubandayo, anikeza izindlela zokusebenzisa eziguquguqukayo.

Yiziphi izinto ezivame ukusetshenziswa kumafilimu ahlanganisiwe ashisayo nabandayo?

Izakhiwo zezinto ezijwayelekile zifaka:
• PET/PE
• I-BOPP/CPP
• Inayiloni/PE
• I-BOPP/PE ene-EVA noma izinamathiselo ezisekelwe ku-solvent.
Lezi zinhlanganisela zinikeza izakhiwo ezifiselekayo njengokuvikela izithiyo, ukumelana nokushisa, ukucaca, kanye nokuvaleka.

Yiziphi izindlela ezivamile zokusebenzisa amafilimu ahlanganisiwe ashisayo nabandayo?

Amafilimu ahlanganisiwe asetshenziswa ezimbonini eziningi ezahlukene, okuhlanganisa:
• Ukupakisha ukudla okuguquguqukayo (izikhwama zokudla okulula, ukudla okuqandisiwe, izikhwama zobisi)
• Ukufakwa kwephepha, amakhadi, noma ukupakisha okuguquguqukayo ngokushisa
• Ukuvalwa kwezikhwama zemithi nezezokwelapha
• Ukufakwa kokuvikela noma ukugoqa okuvikelayo
• Amalebula, izinto zokukhangisa, kanye nemidiya yokunyathelisa enama-laminated
Ukuzivumelanisa kwazo namazinga okushisa kuzenza zilungele izinqubo ezizenzakalelayo noma ezenziwe ngesandla.

Ingabe la mafilimu ahlanganisiwe afanelekela ukupakishwa kokudla?

Yebo, amafilimu amaningi ahlanganisiwe ashisayo nabandayo akhiqizwa ngama-resin nama-adhesive aphephile ekudleni.
Ahlangabezana nemithetho yokuxhumana kokudla ye-FDA, EU, kanye ne-GB futhi anikeza izakhiwo ezinhle kakhulu zokuvimbela umswakama, umoya-mpilo, kanye nephunga.
Avame ukusetshenziswa ezikhwameni ze-vacuum, ezikhwameni zokuphendulela, nasezingxobeni zokudla okulula.

Yiziphi izinzuzo zokusebenzisa amafilimu ahlanganisiwe ashisayo nabandayo?

• Amandla aphezulu okusebenza kanye nokumelana nokubhoboza
• Ukuphrinta okuhle kakhulu kanye nokushelela kwendawo
• Ukubopha okuqinile ngephepha, ibhodi, noma amanye amafilimu
• Ukumelana namafutha, amafutha, namakhemikhali
• Kuyahambisana nezinqubo zokuvala ukushisa kanye nezokuphola
• Ukusebenza kwesithiyo okungenziwa ngezifiso ngezingqimba zensimbi noma zokumboza

Yibuphi ubukhulu obutholakalayo kumafilimu ahlanganisiwe ashisayo nabandayo?

Ubukhulu buyahlukahluka kuye ngesakhiwo sefilimu kanye nokusetshenziswa kwayo, ngokuvamile kusuka kuma-micron angu-20 kuya kuma-micron angu-150.
Amafilimu amancane (isb., ama-micron angu-25-40) asetshenziselwa ukuncibilikisa noma izendlalelo zangaphakathi, kuyilapho amafilimu amakhulu (angaphezu kwama-micron angu-80) enikeza amandla angcono kanye nokuvala ukupakishwa kwangaphandle.
Amafilimu anezendlalelo eziningi angahlanganisa amageyiji ahlukene ukuze kuthuthukiswe ukusebenza.

Ingabe la mafilimu anganyatheliswa noma enziwe ngensimbi?

Yebo, amafilimu amaningi ahlanganisiwe ayaphrintwa ngezindlela ze-gravure, i-flexographic, noma zedijithali.
Izinguqulo zensimbi (njengensimbi PET noma i-BOPP) zinikeza izakhiwo ezithuthukisiwe zokuvimbela kanye nemiphumela ebonakalayo yokupakisha okuphezulu.
Ukwelashwa kwe-corona noma ngamakhemikhali kuqinisekisa ukunamathela okuqinile kwe-inki kanye nokukhiqizwa kombala ogqamile.

Ingabe amafilimu ahlanganisiwe ashisayo nabandayo angaphinde asetshenziswe?

Kuncike ekwakhiweni kwezinto.
Izakhiwo zezinto ezisetshenziswayo zodwa njenge-PE/PE noma i-PP/PP laminates zingasetshenziswa kabusha kakhudlwana.
Amafilimu ahlanganisiwe ezinto eziningi (isb., PET/PE noma i-BOPP/Nylon) kunzima ukuwasebenzisa kabusha kodwa angenziwa abe nobungane nemvelo ngokusebenzisa izinamathiseli ezingenaso isinyibilikisi noma izendlalelo ezibolayo.
Abakhiqizi bayaqhubeka nokuhlinzeka ngamafilimu ahlanganisiwe angasetshenziswa kabusha noma ahlanganisiwe ezinto ezisetshenziswayo zokuxazulula ukupakishwa okusimeme.

Iyini incomo yokugcina kanye nesikhathi sokuphelelwa yisikhathi?

Ngaphansi kwezimo ezifanele zokugcina—ezipholile, ezomile, futhi ezikude nokukhanya kwelanga okuqondile—amafilimu ahlanganisiwe ngokuvamile aphila isikhathi eside kusukela ezinyangeni ezingu-12 kuya kwezingu-18.
Ukugcinwa endaweni elawulwa amazinga okushisa (15–25°C) kuyanconywa ukuvimbela ukugoba, ukulahleka kokunamathela, noma ukuwohloka kokuphrinta.
