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.
