Uninzi lwetape yokupakisha ecacileyo yenziwa kwifilimu yeplastiki eyaziwayo ye-biaxate.Ubukho bepropene bukuxelela ukuba yi-thermoplastic.oku kuthetha ukuba iyakwazi ukuphepheka xa iphezulu kunamanye amaqondo obushushu ize iqine xa izinto zipholile.izinto ezichaseneyo ziyasetyenziswa ke ngoko ekwakhiweni kweeteyiphu zomelele kwaye zibonise ukucaca ukuba kufuneka zibe ngawabo.Ulwakhiwo olubi lweteyiphu yokupakisha lwenza kube lula ukusebenzisa iteyiphu yokupakisha nokuba kungekuko kwincwadana okanye kwisicelo esilawulwa ngumatshini.

Iiteyiphu zokupakisha ze-BOPP ar inani leeteyiphu eziphambili ezidla ngokusetyenziswa ekuthumeleni nasekulawuleni uluhlu lwempahla kule mihla, kwaye ngesizathu esikrelekrele.Ulwakhiwo olukhethekileyo lwemolekyuli kunye nokuzinziswa kwekhompawundi ye-organic yeplastiki ibonelela ngeempawu ezimangalisayo zoomatshini nezokukhanya, eziluncedo kakhulu kuhlobo olugqithisileyo lwezicelo, enye yazo kukupakishwa.

Umbandela

I-tape yokupakisha ye-BOPP yenziwe kwifilimu ye-biaxate yeplastiki eyaziwayo (BOPP).iplastiki isenokuba yikhemikhali ye-thermoplastic (oku kuthetha ukuba inokuphepheka ngaphezulu kobushushu obuthile, kwaye ibuyela kwisimo esiqinileyo xa ipholile).Ngoku, iplastiki eqhelekileyo ye-biaxate inokuba yifilimu ye-PP eyoluliweyo kwinqanaba kunye nomkhombandlela womatshini kunye nomkhombandlela womatshini.Oku kuya kwandisa amandla ukongezelela ngenxa yokucaca kwefilimu.Ulwakhiwo ukongeza lwenza umatshini olawulwayo kunye nesicelo sencwadana ye-tape yokupakisha lula.
