Nebudiriro yemagariro, vanhu vari kuwedzera kukosha kuhutano.Kuchengetedzeka kwechikafu chinhu chikuru chinokanganisa hutano hwevanhu icho chagara chichitorwa sechinhu chikuru nevagadziri vezvekudya vekunze nedhipatimendi rekutarisa.Kurongedza chikafu, kunyanya, iyo yekurongedza inobata zvakananga chikafu, ine hukama zvakananga nehutano hwechikafu, kuenderera kune hutano hwepanyama hwevanhu.nekudaro pane zvakanyanya kuomesesa zvinodiwa pakurongedzerwa kwechikafu munyika dzekunze maererano nehunyanzvi hwekuita uye kuchengetedzwa kwehutano .mumakore achangopfuura, China yakasimbisawo zvinodiwa zvekuchengetedza hutano pakugadzirwa kwechikafu.Zvichienderana nemamiriro ezvinhu aya, zvakakosha kushandisa zvinhu zvekurongedza chikafu nekuchengetedza hutano hwekudya.seyakanyanya kurongedza materia, BOPET firimu rine zvinotevera zvakanaka:
①Yakanaka michina zvivakwa, 3-5 tims inokanganisa mamwe mafirimu, anotsungirira mukupeta.
②Kutsungirira kwakanaka nemafuta, mafuta, olefine asidhi uye mazhinji ezvinonyungudutsa.
③Kutsungirira kwakanaka nekupisa kwakanyanya.inogona kushandiswa kwenguva refu mu120 ℃, muchidimbu, inoshanda mu150 ℃, kusvika -70 ℃, ishoma mhedzisiro pamichina zvinhu.
④Yakaderera gasi uye mhute permeability, yakanaka chipingamupinyi zvivakwa pamvura, oiri uye kunhuhwirira kunovandudza hupenyu hwesherufu.
⑤Firimu repamusoro rakajeka, kunyura kweUV, firimu rakakwirira rinopenya.
⑥ hapana chepfu, hapana kunhuwa, yakanaka heath kuchengetedza chivakwa, inoshandiswa mukurongedza chikafu zvakananga.
Vatengi vanonamatira zvakanyanya uye zvakanyanya kukosha kune chikafu chinotakura hutano chinodiwa, esp.musherufu hupenyu, kutsva uye anti bacteria zvivakwa.saka kudiwa kwekuita kwakanaka kwePET firimu kuri kuwedzera .izvi zvinovandudza hutano hwekutakura chikafu.mumakore achangopfuura pakusarudza zvinhu zvekuputira, kunyanya kusimbiswa kwakaiswa pane zvinhu zvezvinhu, izvi zvakakurumidza kukura kwePET film.
Oxygen permeability chinhu chakakosha pakusarudza chikafu chekurongedza chikafu, chehomwe yekudya yakavharwa zvakanaka, sherufu yehupenyu hwechikafu iri kusvika kune oxygen permeability.kunyanya yevacuum packaging uye anti oxygen packing material.BOPET ine yakanakisa gasi inodzivirira pfuma, pasi petembiricha yekamuri, hupenyu hwesherufu hweBopet yakarongedza chikafu inopeta kaviri Bopp.Kunze kwezvo, Alu.plated Bopet Firimu ine kuita kurinani maererano nekudzivirira paokisijeni uye humbowo hwakanyorova kupfuura Bopp firimu.kunyorova kwemvura yeAlu.firimu reBopet rakapetwa richadzika kusvika pa0.3~0.6 kubva pa40~45.Versus Bopp, 0.8~1.2 zvichidzika kubva pa5~7.(g/mm2.24h.40℃ neAlu. ukobvu 60~70mm)
Kushandiswa kwakawanda kweBopet firimu mukurongedza kunonatsiridza simba, kunoderedza kurongedza zvinhu pahuremu hweyuniti uye pollution.meanwhile, kunowedzerawo tembiricha yemhando, semuenzaniso kubva pakurongedzera kune zvakanaka zvakaomeswa kusvika kune yakakwira temp yakabikwa chikafu. izwi rekushandisa mu120 ℃), rinogona kushandiswa kuovheni yemicrowave.nekukurumidza kwehupenyu hwemazuva ano, chikafu che microwaved chinonakidzwa nemukurumbira mukuru pakati pevanhu.
Bopet firimu ndiyo yakanakisa zvinhu zvesilican dioxide vacuum plating.silicon dioxide firimu inogadzirwa nekuisa girazi firimu paBOPET firimu, kureva iyo barriers property inogadzirwa negirazi layer.saka kuitira kuchengetedza chivhariso pfuma panguva yekuisa uye mukushandisa gare gare, iyo girazi layer inofanira kuchengetedzwa kubva pakukuvadzwa.mashandisirwo nekuvandudzwa kwechivharo chepamusoro BOPET- firimu -vacuum -deposite -silica -oxide -material zvakare yakakurudzira chikafu kurongedza indutry kuenda kune yakakwira pachena, kunyanya kuita, environment hushamwari zvinhu .the vacuum deposit silica dioxide bopet film inonziwo girazi rakapfava, rine basa rimwechete nemabhodhoro egirazi mukuchengeta kunhuhwirira uye haizogadziri chero kunhuhwirira mushure mekuchengetedza kwenguva yakareba kana kurapwa kwakanyanya uye inonakidzwa neAl pfuma mubarriers basa.iyo firimu inoratidza kujeka kwakafanana mushure me slica deposit.saka chikafu chaigona kuoneka zvakajeka kubva pakurongedza izvo zvinokurudzira chishuwo chevatengi.
Hapana zvimwe zvekuwedzera organic zvinowedzerwa muBOPET firimu kugadzirwa, uye zvakare chinhu chakadzokororwa zvinhu zvinoita kuti ive ine hutano, nharaunda inoshamwaridzana kurongedza zvinhu.
