Chipfuwo Chikafu Bag

Parizvino, mabhegi ekurongedzerwa echikafu akaomeswa pamusika anogona kunyanya kukamurwa kuita mabhegi ekurongedza, akasanganiswa emabhegi ekurongedza, uye akawanda-layer co-extruded ekurongedza mabhegi. Composite mapurasitiki akapfava anoshandiswa zvakanyanya mumabhegi akaomeswa echikafu, uye rudzi urwu rwemabhegi ekurongedzerwa echikafu akaomeswa anewo akawanda musanganiswa mukugadzirwa kwezvinhu.

Zvinoenderana nezvinyorwa, kune akati wandei marudzi anogona kushandiswa kurongedza chikafu chakaomeswa. Imwe, PET/PE. Ichi chimiro chenyama chinonyanya kuwanda mukurongedza kwezvikafu zvinokurumidza kutonhora. Iyo ine yakanaka yekudzivirira kunyorova, kutonhora kupikisa, uye yakaderera-tembiricha yekuisa chisimbiso kuita, uye mutengo wekugadzira wakadzikira.

Chechipiri, BOPP/PE uye BOPP/CPP. Iwo mabhegi ekurongedzerwa echikafu akaomeswa ezvivakwa zviviri izvi ane yakanakisa kunyorova uye kudzivirira kutonhora, yakaderera-yekushisa kupisa-kuvharisa kusimba kwesimba, uye hupfumi hwakanaka. Zvakakodzera kutaura kuti BOPP/PE zvinhu zvinonzwa zvirinani pane PET/PE, zvakanakira kushambadzira kwechigadzirwa.

Chechitatu, PET/VMPET/CPE, BOPP/VMPET/CPE. Kuenzaniswa ne-single-layer uye kaviri-layer kurongedza mabhegi, iyo matatu-layer chimiro chakanyanya kusimba uye yakagadzikana, uye ine yakakwirira chipingamupinyi kuita. Pamusoro pezvo, kuvepo kwealuminum layer zvakare kune mukana wakatanhamara mukudhinda kuita. Nekudaro, zvichienzaniswa nemidziyo iri pamusoro, kudziya kwakadzika-tembiricha Kusina chisimbiso kuita uye kudhura kwakanyanya Chechina, PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. Chimiro cheaya marudzi mana ezvishandiso anonyanya kushingirira kutonhora uye kukanganisa, uye iyo PA layer inovimbisa yakanaka puncture kuramba. Izvo zvakashata ndezvekuti mutengo wekugadzira wakakwira, uye unowanzo shandiswa kune angular kana inorema chikafu chigadzirwa kurongedza.
