Umahluko phakathi kweBOPP, i-OPP kunye nePP Bags.

Ishishini lokutya ikakhulu lisebenzisa ukupakishwa kweplastiki yeBOPP.Iingxowa ze-BOPP zilula ukuprinta, iingubo kunye ne-laminate ezenza zilungele ukupakisha iimveliso ezifana neemveliso ezintsha, i-confectionaries kunye ne-snacks.Kunye neBOPP, OPP, kunye neengxowa zePP nazo zisetyenziselwa ukupakishwa.Ipolypropylene yipolymer eqhelekileyo phakathi kwezi zintathu zisetyenziselwa ukwenza iibhegi.

I-OPP imele iOriented Polypropylene, iBOPP imele iBiaxially Oriented Polypropylene kunye nePP imele iPolypropylene.Bobathathu bahlukile kwindlela yabo yokwenza.Ipolypropylene ekwabizwa ngokuba yipolypropene yipolymer ethermoplastic semi-crystalline.Iqinile, yomelele kwaye inokumelana neempembelelo eziphezulu.Iipowutshi zestandup, ii-spout pouches kunye ne-ziplock pouches zenziwe nge-polypropylene.

Kunzima kakhulu ukwahlula phakathi kwe-OPP, i-BOPP kunye neeplastiki zePP ekuqaleni.Umahluko unokuviwa ngokuchukumisa njengoko i-PP ithambile ngelixa i-OPP inobunkunkqele.Kubalulekile ukuqonda ukusetyenziswa kwe-OPP, i-PP kunye neengxowa ze-BOPP kwizinto zangempela zehlabathi zokuzahlula.IPPokanye iingxowa ze-polypropene zisetyenziswa njengeengxowa ezingalukwanga.Ziyanyangwa ukuze zenziwe ukufuma okanye ukufunxa amanzi.

I-diapers, i-napkins yangasese kunye nezihlungi zomoya phakathi kwezinye ziyimveliso yePP eqhelekileyo.Izinto ezifanayo zikwasetyenziselwa ukwenza iimpahla ezishushu njengoko zibonelela ngomqobo wobushushu.Iingxowa ze-OPP zibonakala ngombala kwaye zinamandla aphezulu.Ziyakwazi ukumelana namaqondo obushushu aphezulu kodwa ziyashwabana xa zisetyenziswe ngokurhabaxa.Iiteyiphu ezincamathelayo ezicacileyo zenziwe kusetyenziswa ifomula efanayo.

Kunzima ukukrazula kwaye iingxowa ze-OPP zisetyenziselwa ukupakishwa kwesikhumba kunye neempahla phakathi kwabanye.Iingxowa ze-BOPP ziingxowa ze-polyethylene ezicacileyo.I-biaxial orientation ibanika inkangeleko ecacileyo kwaye ibenza bafaneleke ukuphawula ngokushicilela kumphezulu.Iingxowa zeBOPP zisetyenziselwa ukupakishwa kweentengiso.I-biaxial orientation yandisa amandla kwaye banokuthwala imithwalo enzima.

Ezi ngxowa azinamanzi.

Iimveliso ezingaphakathi kuzo zikhuselwe kumswakama ixesha elide.Zikhetho lokuqala kwishishini lokupakisha ilaphu.Iingxowa ze-PP, i-OPP kunye ne-BOPP zichasene ne-asidi, i-alkali kunye ne-solvents eziphilayo.Esi sizathu sokuba zisetyenziswe kwishishini lokupakisha apho ukugcinwa kunye nokuthuthwa phantsi kwe-atmosphere eguqukayo akunakuthintelwa.Benza imveliso ngokufuma kunye nothuli njengeefilimu zokutya.

Zinokuphinda zisetyenziswe kwaye ukwenziwa kwazo kubandakanya ukukhutshwa kwekhabhoni encinci.Iingxowa ze-PP, ze-BOPP kunye ne-OPP nazo zilungile ukusuka kwindawo yokujonga indawo.I-Rishi FIBC ngumenzi wengxowa ye-BOPP kwaye ibonelela ngamaxabiso afikelelekayo emarike.
