Iingxowa zephepha eziphothiweyo ze-PP luhlobo lwengxowa yokupakisha eyenziwe ngokudityaniswa kwe-polypropylene (PP) ilaphu elilukiweyo kunye nephepha le-kraft.Ilaphu elilukiweyo lePP libonelela ibhegi ngamandla aphezulu, ukuqina, kunye nokuchasana nokukrazula kunye nokugqobhoza, ngelixa iphepha le-kraft longeza umaleko owongezelelweyo wamandla kunye nokuqina kwingxowa.
Ezi ngxowa ziqhele ukwenziwa kusetyenziswa inkqubo ebizwa ngokuba yi-lamination, apho ilaphu elilukiweyo lePP lidityaniswe kwiphepha le-kraft lisebenzisa ubushushu kunye noxinzelelo.Isiphumo sisikhwama esinamandla kwaye siguquguqukayo, esenza ukuba silungele uluhlu olubanzi lwezicelo.
