Pepa-plastiki inosanganiswa bhegi

Kazhinji iyo yepurasitiki layer inogadzirwa nejira rakapfava rakarukwa nePP kana PE sechinhu chekutanga, uye kunze kunogadzirwa neyakacheneswa chena kraft bepa kana yero kraft bepa.Kraft bepa rakagadzirwa neyakakwenenzverwa composite yakakosha kraft bepa, ine hunhu hwekusimba kwepamusoro, kumira zvakanaka kwemvura uye kutaridzika kwakanaka.Icho chimwe chezvinhu zvakakurumbira zvekurongedza zvinhu uye chinoshandiswa zvakanyanya mukudya, zvipfeko, zvipo uye mamwe maindasitiri.Mabhegi ekurongedza anogona kukamurwa kuita mabhegi akavharirwa kumashure, matatu-mativi akavharwa mabhegi, mabhegi enhengo, zipper stand-up mabhegi, mabhegi mana-akavharwa, mabhegi akasarudzika, nezvimwe.

Chikwama chekumira chakaiswa laminated nePET/foil/PET/PE chimiro, uye chinogona zvakare kuve nezvimwe zvakatemwa senge 2 layer uye 3 layer.Zvinoenderana neakasiyana zvigadzirwa zvakaputirwa, iyo oxygen barriers inodzivirira layer inogona kuwedzerwa sezvinodiwa kudzikisa iyo oksijeni permeability uye kurebesa hupenyu hwesherufu yechigadzirwa.

Pahwaro hweakajairwa mapochi ekumira, takatangisa mamwe qual-seal flat pazasi stand up pouch, ine zvinotevera zvakanakira:

1. Vertical structure, inogona kumira pasherufu yakaoma, sikweya yacho yakati sandara, uye kumira kwakagadzikana.

2. Yakawedzerwa yekuisa chisimbiso zipper inogona kuwedzerwa kuti udzivise kushata iyo mhando yebhegi yenhengo haigone kuvharwa.

3. A-one-way exhaust valve inogona kusungirirwa, iyo inogona kushandiswa mukofi uye mamwe maindasitiri ane hukama.

4. The composite flexible packaging material inogona kubatanidzwa kuti iite zvakasiyana-siyana zvakashata zvipingamupinyi kuburikidza nemvura uye oksijeni permeability zvinhu zvakasiyana-siyana.
