(4) Tembiricha yakafaranuka, ine nzvimbo yekunyungudika ye225 ℃, uye inogona kushandiswa kwenguva yakareba pakati -60 ~ 130 ℃. Iyo mechanic properties yeBOPA inoramba yakagadzikana pane yakaderera uye yakakwirira tembiricha.
(5) Kuita kweBOPA firimu kunokanganisa zvakanyanya nehunyoro, kunyanya maererano nekugadzikana kwedimensional uye zvipingamupinyi zvivakwa. Mushure mekunyorova, firimu reBOPA rinowanzorebesa padivi, kunze kwekukwinya. Kupfupisa kwenguva refu, nekurebesa kukuru kwe1%.
3. CPP firimu
CPP firimu, rinozivikanwawo se cast polypropylene firimu, isiri kutambanudza, isina kutariswa polypropylene firimu. Yakakamurwa kuita homopolymer CPP uye copolymer CPP zvinoenderana neyakagadzirwa zvinhu. Iyo huru mbishi yekubika giredhi CPP firimu ndeye block copolymer kukanganisa inopikisa polypropylene. Zvinodiwa zvekuita ndezvi: tembiricha yekunyorovesa yeVicat inofanira kunge yakakwira kupfuura tembiricha yekubikira, kupikisa kunofanirwa kuve kuri nani, kupikisa kwepakati kunofanirwa kunge kuri nani, uye ziso rehove nekristaro poindi inofanira kunge iri shoma sezvinobvira.
4. Aluminium foil
Aluminium foil ndiyo chete mhando yesimbi foil mune zvinyoro zvekurongedza zvinhu, zvinoshandiswa kurongedza zvinhu zvine nguva refu yekushandisa. Aluminium foil isimbi ine isingaenzaniswi yekudzivirira kwemvura, gasi kuramba, mwenje kudzivirira, uye flavour yekuchengeta zvivakwa zvichienzaniswa chero ipi zvayo yekurongedza. Icho chinhu chekuputira chisingagoni kutsiviwa zvachose kusvika nhasi.
5. Ceramic evaporation coating
Ceramic vapor coating imhando nyowani yekurongedza firimu, iyo inowanikwa nekuputira simbi oxides pamusoro pepurasitiki firimu kana bepa seiyo substrate mune yakakwira vacuum midziyo. Hunhu hweceramic vapor coating inonyanya kusanganisira:
(1) Yakanakisa chipingamupinyi kuita, ingangoita kuenzaniswa nealuminium foil composite zvinhu.
(2) Kujeka kwakanaka, microwave permeability, yakakwirira tembiricha kuramba, yakakodzera microwave chikafu.
(3) Kuchengetedza kunhuhwirira kwakanaka. Mhedzisiro yacho yakafanana negirazi kurongedza, uye haizoburitsa chero kunhuhwirira mushure mekuchengetedza kwenguva refu kana kupisa kwakanyanya.
(4) Ushamwari hwakanaka hwemhoteredzo. Kupisa kwakadzika uye zvishoma zvakasara mushure mekupisa.
6. Mamwe mafirimu akaonda
(1) PEN firimu
Chimiro chePEN chakafanana nePET, uye ine zvakasiyana-siyana zvePET, uye zvinenge zvese zvayo zvakakwirira kudarika PET. Yakanakisa mashandiro akazara, simba repamusoro, kunaka kwekudzivirira kupisa, kuita kwakanaka kwezvipingamupinyi, uye kujeka. Iyo yakasarudzika UV kuramba ndiyo yakanyanya kukwirisa yePEN. PEN inodzivirira pamhute yemvura yakapetwa ka3,5 pane yePET, uye inodzivirira kumagasi akasiyana-siyana inopeta nekana yePET.
