Ishishini lokutya lisebenzisa kakhulu iipakethe zeplastiki zeBOPP. Iingxowa zeBOPP kulula ukuziprinta, ukuzigquma kunye nokuzifaka ilaminethi nto leyo eyenza ukuba zilungele ukupakisha iimveliso ezifana neemveliso ezintsha, iilekese kunye nezimuncu. Kunye neengxowa zeBOPP, OPP, kunye nePP nazo zisetyenziselwa ukupakisha. I-Polypropylene yipolymer eqhelekileyo phakathi kwezintathu ezisetyenziselwa ukwenza iingxowa.
I-OPP imele i-Oriented Polypropylene, i-BOPP imele i-Biaxially Oriented Polypropylene kunye ne-PP imele i-Polypropylene. Zontathu zahlukile ngendlela yazo yokwenza. I-Polypropylene ekwaziwa ngokuba yi-polypropene yi-thermoplastic semi-crystalline polymer. Iqinile, yomelele kwaye inokumelana okukhulu. Iipokotshi ezimileyo, iipokotshi ze-spout kunye neepokotshi ze-ziplock zenziwe nge-polypropylene.
Kunzima kakhulu ukwahlula phakathi kwe-OPP, BOPP kunye neplastiki yePP ekuqaleni. Umahluko unokuviwa ngokuchukumisa njengoko i-PP ithambile ngelixa i-OPP ibuthathaka. Kubalulekile ukuqonda ukusetyenziswa kweengxowa ze-OPP, PP kunye ne-BOPP kwizinto zokwenyani ukuze zibonakale.PPokanye iingxowa zepolypropene zisetyenziswa njengeengxowa ezingalukwanga. Ziphathwa ukuze zifume okanye zifunxe amanzi.
Iinapile, ii-napkin zokucoca kunye nee-air filters phakathi kwezinye ziimveliso zePP eziqhelekileyo. Izinto ezifanayo zikwasetyenziselwa ukwenza iimpahla ezishushu kuba zibonelela ngomqobo wobushushu. Iingxowa ze-OPP zinombala ocacileyo kwaye zinamandla aphezulu okutsalwa. Ziyakwazi ukumelana namaqondo obushushu aphezulu kodwa ziyashwabana xa zisetyenziswa nzima. Iiteyiphu zokuncamathelisa ezicacileyo zenziwa kusetyenziswa indlela efanayo.
Kunzima ukuzikrazula kwaye iingxowa ze-OPP zisetyenziswa ekupakisheni isikhumba kunye neempahla phakathi kwezinye. Iingxowa ze-BOPP ziingxowa ze-polyethylene ezicacileyo. Ukuma kwe-biaxial kuzenza zibonakale zicacile kwaye kuzenze zilungele ukuphawulwa ngokuprinta kumphezulu. Iingxowa ze-BOPP zisetyenziselwa ukupakisha kwivenkile. Ukuma kwe-biaxial kwandisa amandla kwaye zinokuthwala imithwalo enzima.
Ezi ngxowa azinamanzi.
Iimveliso ezingaphakathi kuzo zikhuselekile kumswakama ixesha elide. Ziyeyona ndlela ikhethwayo kuqala kushishino lokupakisha amalaphu. Iingxowa zePP, OPP kunye neBOPP ziyamelana ne-asidi, ii-alkali kunye nezinyibilikisi zendalo. Yiyo le nto zisetyenziswa kushishino lokupakisha apho ukugcinwa kunye nokuthuthwa phantsi kwemozulu etshintshayo akunakuphepheka. Zivelisa imveliso ukusuka kumswakama kunye nothuli olufana neefilimu zokuncamathela.
Zingaphinda zisetyenziswe kwaye ukwenziwa kwazo kubandakanya imveliso encinci yekhabhoni. Iingxowa zePP, zeBOPP kunye neze-OPP nazo zilungile ngokwembono yokusingqongileyo. IRishi FIBC ngumvelisi weengxowa zeBOPP kwaye ibonelela ngazo ngamaxabiso afikelelekayo kwimarike.
