Yintoni i-kraft paper

Iphepha le-Kraft liphepha okanye i-paperboard eyenziwe kwi-pulp yekhemikhali eveliswe ngokusebenzisa inkqubo yephepha le-kraft. Ngenxa yenkqubo yephepha le-kraft, iphepha lokuqala le-kraft linobunzima, ukunganyangeki kwamanzi, ukuxhathisa ukukrazula, kunye nombala ophuzi omdaka.

Intlama yesikhumba senkomo inombala omnyama kunezinye iinkuni, kodwa inokuqatywa ibleach ukwenza intlama emhlophe kakhulu. Intlama yesikhumba senkomo etshiswe ngokupheleleyo isetyenziselwa ukwenza iphepha elikumgangatho ophezulu, apho amandla, ubumhlophe, kunye nokuxhathisa okumthubi kubalulekile.

Umahluko phakathi kwephepha le-kraft kunye nephepha eliqhelekileyo:

Mhlawumbi abanye abantu banokuthi, liphepha nje, yintoni ekhethekileyo ngalo? Ukubeka nje, iphepha le-kraft lomelele ngakumbi.

Ngenxa yenkqubo yephepha le-kraft elikhankanywe ngaphambili, ukhuni oluninzi luxotyulwa kwi-pulp ye-kraft yephepha, ishiya imicu emininzi, ngaloo ndlela inika iphepha ukuchasana nokukrazula kunye nokuqina.

Iphepha eliphambili le-kraft elinombala lihlala lisiba ngaphezulu kunephepha eliqhelekileyo, elenza ukuba isiphumo salo soshicilelo sibe mandundu kancinane, kodwa ifanelekele kakhulu impembelelo yeenkqubo ezithile ezikhethekileyo, ezinje nge-embossing okanye isitampu esishushu.
