•Isu tinoda kudaidza epurasitiki inochinjika packaging composite yekurongedza mabhegi.

•Kutaura zvazviri, zvinoreva kuti zvinhu zvemufirimu zvezvinhu zvakasiyana zvakabatanidzwa uye zvinosanganiswa kuita basa rekutakura, kudzivirira nekushongedza zvigadzirwa.

•Composite packaging bag zvinoreva dangwe rezvinhu zvakasiyana zvakabatanidzwa pamwechete.

•Iwo makuru akaturikidzana emabhegi ekurongedzerwa anowanzosiyaniswa neyekunze layer, yepakati layer, yemukati layer, uye adhesive layer.Izvo zvinosanganiswa mumitsara yakasiyana-siyana maererano nemaitiro akasiyana.

•Rega YPAK ikutsanangurire zvikamu izvi:

•1.Iyo yekunze kwekunze, iyo inonziwo chinyorwa chekudhinda uye nheyo yepasi, inoda zvinhu zvine maitiro akanaka ekudhinda uye zvakanaka optical properties, uye zvechokwadi kupisa kwakanaka kwekupisa uye simba remagetsi, zvakadai seBOPP (yakatambanudzwa polypropylene), BOPET, BOPA, MT. , KOP, KPET, polyester (PET), naironi (NY), bepa uye zvimwe zvinhu.

•2. Chikamu chepakati chinonziwo barrier layer.Iyi nhanho inowanzoshandiswa kusimbisa chimwe chimiro chechimiro chakaumbwa.Inoda kuve neyakanaka inodzivirira zvivakwa uye yakanaka poly hunyoro-huchapupu basa.Parizvino, akanyanya kuwanda pamusika ialuminium foil (AL) uye aluminium-plated firimu (VMCPP)., VMPET), polyester (PET), naironi (NY), polyvinylidene chloride coated film (KBOPP, KPET, KONY), EV, nezvimwewo.

•3. Mutsara wechitatu ndiyo zvakare yemukati yemukati, inonziwo kupisa sealing layer.Chimiro chemukati chinowanzo sangana zvakananga nechigadzirwa, saka zvinhu zvinoda kuchinjika, permeability kuramba, yakanaka kupisa sealability, pachena, kuvhurika uye mamwe mabasa.

•Kana chiri chikafu chakaputirwa, chinodawo kunge chisina chepfu, chisina kunaka, chinodzivirira mvura, uye chinodzivirira mafuta.Zvinowanzoshandiswa zvinosanganisira LDPE, LLDPE, MLLDPE, CPP, VMCPP, EVA (ethylene-vinyl acetate copolymer), EAA, E-MAA, EMA, EBA, Polyethylene (PE) uye zvinhu zvayo zvakagadziridzwa, nezvimwewo.
