Ulwazi olusisiseko lwefilimu yeplastiki

Kwi-NATIONAL PACKAGING GENERAL terms (GB4122-83), inkcazo ye-flexible packaging ithi: i-flexible packaging ibhekisa kwi-packaging enokutshintsha imo yesikhongozeli emva kokuzalisa okanye ukususa umxholo. Zonke iintlobo zeengxowa, iibhokisi, iiseti kunye neemvulophu ezenziwe ngephepha, i-aluminium foil, i-fiber, i-plastic film kunye nee-complexes zazo zi-flexible packaging. Ngokubanzi, iiplastiki zephepha ezinobukhulu obungaphantsi kwe-0.25mm zibizwa ngokuba ziifilimu. Ifilimu yeplastiki ibonakala ngokucacileyo, iguquguqukayo, inokumelana kakuhle kwamanzi, ukumelana nokufuma kunye nokumelana nomoya, amandla alungileyo oomatshini, iipropati zeekhemikhali ezizinzileyo, ukumelana neoyile, kulula ukuprinta umbhalo ocolekileyo, i-can heat seal bag. Ingahlangabezana neemfuno ze-packaging zazo zonke iintlobo zezinto, isetyenziswa kwi-packaging elula ukuyigcina, kulula ukuyibeka ukutya okulula, izinto ezifunekayo zemihla ngemihla, i-supermarket small package products, izinto ezifanelekileyo. I-Guangdong Danqing Printing Co., Ltd ineminyaka engama-30 yamava kwi-flexible packaging manufacturing, ikakhulu ivelisa i-spout pouch, i-stand up zipper bag, i-plastic roll film njalo njalo; Inikezela ngoshicilelo oluhle, ingaprinta ukuya kuthi ga kwi-13 colors.

Ukuprinta iipakethe eziguquguqukayo ezisekelwe kwifilimu yeplastiki kudlala indima ebalulekileyo ekuprinteni iipakethe. Ngokwezibalo, ukusukela ngo-1980, ukupakishwa kweplastiki kwamanye amazwe aphuhlileyo kwihlabathi kuxabisa i-32.5% ukuya kwi-44% yoshicilelo lonke lweepakethe.

Ngokubanzi, kuba izinto zefilimu enye azilungelanga ukukhusela ingaphakathi, ngoko ke kusetyenziswa iintlobo ezingaphezu kwezibini zeefilimu ukuze zihlanganiswe zibe ngumaleko wefilimu edityanisiweyo, ukuhlangabezana neemfuno zokugcina ukutya, iteknoloji yokupakisha i-aseptic. Ukukhetha izinto zangaphandle zefilimu edityanisiweyo akulula ukuzikrwela, ukuzigugisa, ukusebenza kakuhle kwe-optical, ukusebenza kakuhle kokuprinta kwezinto, ezifana nephepha, i-cellophane, i-polypropylene ethambileyo, i-polyester, njl.njl.; Umaleko ophakathi yi-polymer ethintelayo, efana ne: i-aluminium foil, i-aluminium ephekiweyo, izixhobo zombane ze-polyvinyl diazene zikhethwa kakhulu njenge-polyethylene engenabungozi, engenancasa kunye nezinye i-resin ye-thermoplastic.
