Ubwoko bwa Polypropilene: Kuzuza OPP, BOPP, na CPP Filime

Filime ya OPP ni firime ya polypropilene yitwa co-extruded orient polypropylene (OPP) kuko inzira yo kuyikora ni ugusohora ibice byinshi. Niba hari inzira-yo kurambura inzira yo gutunganya, byitwa bi-icyerekezo cyerekanwe na polypropilene film (BOPP). Ibindi ni firime ya polypropilene (CPP), aho kugirango bafatanyirize hamwe. Imiterere nimikoreshereze ya firime eshatu ziratandukanye.

UP Filime:Ibyingenzi

OPP: yerekanwe na polypropilene (firime), polypropilene ndende, ni polypropilene. Ibicuruzwa nyamukuru bya OPP:

1. Kanda: Filime ya polypropilene nka substrate, ifite imbaraga zingana cyane, zoroheje, zidafite uburozi, uburyohe, zangiza ibidukikije, uburyo bwinshi bwo gukoresha, nibindi byiza;
2. Amacupa ya OPP: Umucyo woroshye, uhendutse, gukorera mu mucyo, kurwanya ubushyuhe bwiza, bikwiranye no kuzuza ubushyuhe.
3. Ibirango bya OPP : Ugereranije n'ibirango by'impapuro, bifite ibyiza byo gukorera mu mucyo, imbaraga nyinshi, kurwanya ubushuhe, kandi ntibyoroshye kugwa. Nubwo igiciro cyiyongereye, urashobora kubona label nziza yerekana kandi ugakoresha ingaruka. Hamwe niterambere ryibikorwa byo gucapa murugo hamwe nubuhanga bwo gutwikira, gukora ibicuruzwa bya firime yifata hamwe no gucapa ibirango bya firime ntibikiri ibibazo; birashobora guhanurwa ko imikoreshereze yimbere murugo ya OPP izakomeza kwiyongera.

BOPP Filime: Guhinduranya no gusaba

BOPP: firime ya polypropilene yerekanwe, kandi ubwoko bwa polypropilene.

Filime BOPP ikunze gukoreshwa harimo firime isanzwe ya polypropilene yerekanwe, ubushyuhe-bushobora gushyirwaho biaxial yerekanwe na polypropilene, firime ipakira itabi, firime yisaro ya polypropilene yerekana amashusho, firime ya polypropilene yerekana ibyuma, firime ya matte nibindi.

Filime ya BOPP nayo ifite ibitagenda neza, nko kwegeranya byoroshye amashanyarazi ahamye no kubura ubushyuhe. Mu murongo wihuta cyane, umurongo wa BOPP ukunda amashanyarazi ahamye, bityo rero hakenewe gushyirwaho amashanyarazi ahamye. Kugirango ubone ubushyuhe bwa BOPP ya firime, BOPP ya firime ya corona ivura irashobora gushyirwaho hamwe nubushyuhe bwo gufunga resin yifata, nka PVDC latex, EVA latex, nibindi, birashobora kandi gushyirwaho ibishishwa, ariko nanone bishobora gutwikirwa hamwe gufatanya gukuramo uburyo bwo gukora ubushyuhe bwa kashe ya BOPP.

Porogaramu nyamukuru ya firime zitandukanye nizi zikurikira:

1. Filime isanzwe ya BOPP: Ahanini ikoreshwa mugucapura, gukora imifuka, kaseti ifata, no guhuza hamwe nandi masomo.
2. BOPP Ubushyuhe bwa firime: Ahanini ikoreshwa mugucapa, gukora imifuka, nibindi.
3. BOPP Gupakira Itabi: Yifashishijwe mugupakira itabi ryihuta.
4. BOPP Pearlescent: Ikoreshwa mubiryo n'ibikoresho bya buri munsi bipakira nyuma yo gucapa.
5. BOPP Yerekana FilimeIkoreshwa mu isabune, ibiryo, itabi, kwisiga, ibikomoka ku miti, nibindi bisanduku bipakira.
6. Matte BOPP: Ikoreshwa mu isabune, ibiryo, itabi, kwisiga, ibikomoka ku miti, nibindi bisanduku bipakira.

Filime ya CPP: Ibyiza nibishoboka

C gukorera mu mucyo, kurabagirana kwinshi, gukomera kwiza, inzitizi yubushyuhe bwamajwi, kurwanya ubushyuhe bwiza, gufunga ubushyuhe bworoshye, nibindi.

CPP firime nyuma yo gucapa, gukora imifuka, ibereye

1. Imyenda, imyenda, n'imifuka yindabyo
2. Inyandiko na alubumu firime
3. Gupakira ibiryo
4. Filime yicyuma ikwiranye no gupakira inzitizi no gushushanya

Mubishobora gukoreshwa harimo kandi ibiryo byuzuye, ibirungo byuzuye (firime yagoretse), gupakira imiti (imifuka ya infusion), gusimbuza PVC muri alubumu, mububiko, hamwe ninyandiko, impapuro zogukora, kaseti yifata, amakarita yubucuruzi, abahuza impeta, hamwe no kwihagararaho. umufuka.

CPP ifite ubushyuhe bwiza cyane. Kubera ko koroshya ingingo ya PP igera kuri 140 ° C, ubu bwoko bwa firime burashobora gukoreshwa mukuzuza ubushyuhe, imifuka ihumeka, gupakira aseptic, nibindi bice. Nibikoresho byo guhitamo ahantu nko gupakira ibicuruzwa byumugati cyangwa laminates, hamwe na aside nziza, alkali, hamwe no kurwanya amavuta. Ni byiza guhura nibiryo, bifite uburyo bwiza bwo kwerekana, ntabwo bigira ingaruka kuburyohe bwibiryo imbere, kandi ibyiciro bitandukanye bya resin birashobora gutoranywa kugirango ubone ibiranga byifuzwa.
