Kutulutsa filimu ya BOPP kukupitirirabe, ndipo makampaniwa ali ndi mwayi waukulu wopita patsogolo.

Kanema wa Biaxially oriented polypropylene (filimu ya BOPP mwachidule) ndipang'onopang'ono yowonekera bwino yosinthira zinthu.Biaxially oriented polypropylene filimu ali ndi ubwino wa mkulu thupi ndi makina mphamvu, kuwala kuwala, sanali kawopsedwe, kukana chinyezi, lonse ntchito osiyanasiyana ndi ntchito khola.Malinga ndi ntchito zosiyanasiyana, filimu ya polypropylene yopangidwa ndi biaxially imatha kugawidwa mufilimu yosindikiza kutentha, filimu yolembera, filimu ya matte, filimu wamba ndi filimu ya capacitor.

Polypropylene ndi chinthu chofunikira chopangira filimu ya biaxially oriented polypropylene.Polypropylene ndi thermoplastic synthetic resin yokhala ndi ntchito yabwino kwambiri.Ili ndi ubwino wokhala ndi kukhazikika kwabwino, kukana kutentha kwakukulu komanso kutsekemera kwamagetsi kwamagetsi, ndipo ikufunika kwambiri m'munda wolongedza.Mu 2021, dziko langa la polypropylene (PP) lidzafika matani 29.143 miliyoni, kuwonjezeka kwa chaka ndi 10.2%.Kupindula ndi zinthu zokwanira zopangira, makampani opanga mafilimu a biaxially oriented polypropylene akukula mofulumira, ndipo zotsatira zake zikupitirira kuwonjezeka.Malinga ndi deta yochokera ku National Bureau of Statistics, filimu ya biaxially oriented polypropylene ya dziko langa idzafika matani 4.076 miliyoni mu 2021, kuwonjezeka kwa chaka ndi 8.7%.

Njira zopangira filimu ya biaxially oriented polypropylene imaphatikizapo njira ya filimu ya tubular ndi njira ya filimu yosalala.Chifukwa cha kusalinganika kwabwino komanso kuchepa kwa zinthu zomwe zimapangidwa ndi njira ya tubular membrane, zimathetsedwa pang'onopang'ono ndi mabizinesi akuluakulu.Njira ya filimu yosalala ikhoza kugawidwa mu nthawi imodzi yotambasula ya biaxial ndi njira yotambasula ya stepwise biaxial.Njira yotambasulira pang'onopang'ono ya biaxial ili motere: zopangira → kutulutsa → kuponyera → kutambasula kwautali → kudula m'mphepete → chithandizo cha corona → kupindika → mpukutu waukulu → kukalamba → kuseta → chinthu chomaliza.Pakadali pano, njira yotambasulira pang'onopang'ono ya biaxial imatengedwa ndi mabizinesi ambiri chifukwa chaubwino wake waukadaulo wokhwima, kupanga bwino kwambiri, komanso kukwanira pakupanga zinthu zambiri.

Biaxially oriented polypropylene film imagwiritsidwa ntchito kwambiri pakuyika zinthu monga zovala, chakudya, mankhwala, kusindikiza, fodya ndi mowa.Pakadali pano, filimu ya biaxially oriented polypropylene pang'onopang'ono yalowa m'malo mwa mafilimu wamba monga polyethylene (PE), polypropylene (PP), ndi polyvinyl chloride (PVC).dziko langa ndi dziko lachiwiri lalikulu kwambiri padziko lonse lapansi, ndipo kufunikira kwa ma CD kukukulirakulira.Malinga ndi ziwerengero zochokera ku China Packaging Federation, ndalama zochulukirapo zamabizinesi zomwe zili pamwamba pa kukula kwake m'makampani azonyamula katundu mdziko langa zidzafika 1,204.18 biliyoni ya yuan mu 2021, kuwonjezeka kwa chaka ndi 16.4%.Ndi chitukuko chofulumira chamakampani olongedza katundu mdziko langa, filimu ya biaxially oriented polypropylene idzakhala ndi chiyembekezo chamsika ngati chinthu chofunikira pakuyika.

Ofufuza zamakampani ochokera ku Xinsijie adati kupindula ndi kupezeka kokwanira kwa zida zopangira komanso kukhwima kwaukadaulo wopanga, kuthekera kotukuka kwamakampani opanga mafilimu a polypropylene mdziko langa ndikwambiri.Kukula kwachangu kwamakampani olongedza zinthu kudzayendetsa kukulirakulira kwa msika wamakanema amdziko langa a biaxially oriented polypropylene.Ndikukula kwa lingaliro la kugwiritsira ntchito zobiriwira, ogula apititsa patsogolo zofunikira zazinthu zonyamula katundu, ndipo filimu yopulumutsa mphamvu komanso yoteteza chilengedwe ya biaxially oriented polypropylene idzakhala yaikulu pamsika.
