Mushure mekutariswa kwemafirimu eBOPP, une kusanzwisisa kwakashata kweichi chinhu chinowanikwa? Mune ino blog, isu tichadzamisa nzwisiso yedu kune zvayakanakira nezvayakaipira, nokudaro zvirinani kunanga zvido zvevatengi.
Chii chinonzi BOPP Firimu
Biaxially Oriented Polypropylene (BOPP) firimu rakashandura indasitiri yekurongedza kubva payakatangwa muma1970s. Ichi chinyorwa chekuvandudza, chakatambanudzwa zvese nemuchina uye nemaoko uchishandisa mchinji-nzira nzira, inopa yakasarudzika musanganiswa wezvivakwa izvo zvaita kuti zvive zvakakosha mukushandisa kwakasiyana.

Izvi zvivakwa zvakaisa BOPP sechinhu chinochinja-chinja mumaindasitiri akati wandei, kubva pakurongedza chikafu kusvika kune machira lamination.
Zvakanakira zveBOPP Firimu
Zvinhu Zvenyama
BOPP inokunda musimba uye kusimba, iine simba rekusimba rinogona kusvika ku300 MPa munzira yemuchina. Chitarisiko chayo chekristaro-chakajeka, chine mwero wekutapurirana mwenje unosvika 90%, inosimudzira kuoneka kwechigadzirwa pamasherufu ezvitoro. Kugadzikana kwemufirimu uyu kunovimbisa kushanda kwakafanana mumashandisirwo akasiyana siyana, neakajairika shrinkage rates iri pasi pe4% pa130°C.
Kupokana kune punctures uye flex kutsemuka kunoita kuti BOPP ive yakanakira yekudzivirira kurongedza. Semuyenzaniso, firimu re20-micron BOPP rinogona kumira kusvika 130 g/25 μm mune dart kukanganisa bvunzo, ichiratidza kusimba kwayo mumashandisirwo epasirese.
Chemical Properties
BOPP inoita sechipinganidzo chinotyisa kurwisa unyoro, kusvibiswa, uye makemikari anokuvadza. Huwandu hwekutapurirana kwehupfu hwemvura hwayo (WVTR) hunogona kudzikira se4-5 g/m²/zuva pa38°C uye 90% hunyoro hunoenderana, zvichiita kuti ive sarudzo yakanaka kune zvigadzirwa zvinonzwa kunyorova.
Iyo firimu mafuta uye girizi kuramba, ine akajairwa kukosha anopfuura 7 paKit test scale, inowedzera kuwedzera kushanda kwayo. Izvi zvivakwa zvinoita kuti BOPP ive sarudzo yakanakisa yekurongedza chikafu uye maindasitiri ekushandisa, uko kuchengetedzwa kwechigadzirwa kwakakosha.
Environmental Benefits
Munyika yanhasi inoziva eco, BOPP inopenya nehunhu hwayo hwezvakatipoteredza:
Recyclability : BOPP inowira pasi pekudzokorora kodhi #5 (PP), ichiita kuti ishandiswe zvakare.
Huremu : Madhindindi chaiwo akatenderedza 0.90-0.92 g/cm³ anobatsira kuderedza kuburitswa kwezvifambiso.
Kugadzirwa kwesimba-inoshanda : Iyo nzira yekugadzira inoshandisa shoma simba kana ichienzaniswa nezvimwe zvimwe zvinhu.
Ongororo yekuongorora kutenderera kwehupenyu yakaitwa neEuropean Polypropylene Film Manufacturers Association yakawana kuti mafirimu eBOPP ane 40% yakaderera kabhoni tsoka kana zvichienzaniswa neakaenzana PET mafirimu.
Zvakanakira Zveupfumi
BOPP inopa zvakakosha mutengo mabhenefiti nekuda kwegoho rayo repamusoro. Huremu hwayo hunosvika 0.90-0.92 g/cm³ hunoita kuti firimu riwande pahuremu hweyuniti zvichienzaniswa nedzimwewo dzakaita sepolyester (density ~1.4 g/cm³). Izvi zvinoturikira kukuchengetedza mari mune zvese zvekushandisa uye zvekufambisa.
Kugamuchirwa kwepasirese kunofambisa kutengeserana kwepasirese uye kutumira. Zvinoenderana nemishumo yeindasitiri, dunhu reAsia-Pacific rinotonga musika weBOPP, uchiverengera pamusoro pe60% yepasi rose yekugadzira.
