Ngokusetshenziswa “kokuvinjelwa kwepulasitiki” kanye nokuthuthukiswa kokuqwashisa kwawo wonke umuntu ngokuvikelwa kwemvelo, izinga lokusetshenziswa kwezikhwama zepulasitiki lehliswe kakhulu, futhi wonke umuntu useqalile ukusebenzisa izikhwama zokuvikela imvelo noma izikhwama zamaphepha.Njengoba sonke sazi, iphepha liwumthombo ongasetshenziswa kabusha futhi usetshenziswe kabusha.Impahla eluhlaza yokwenza iphepha ikakhulukazi imicu yezitshalo.Ngaphandle kwezingxenye ezintathu eziyinhloko ze-cellulose, i-hemicellulose ne-lignin, kunezinye izingxenye ezinokuqukethwe okuncane.Okufana ne-resin, umlotha, njll. Ake sixoxe ngomehluko phakathi kwephepha lesikhwama sephepha nephepha le-kraft.
Okokuqala, inqubo yokukhiqiza yephepha lesikhwama sephepha kanye nephepha le-kraft lifana kakhulu.Iphepha lesaka likhiqizwa kusetshenziswa i-wood fiber kusuka ku-softwood kanye ne-kraft pulp.Kodwa-ke, izinga lephepha lesikhwama sephepha ngokuvamile liphansi kunalelo lephepha le-kraft, ngoba, ukuze kongiwe izindleko zokukhiqiza, amanye amabhizinisi azokwengeza i-pulp yesiqu sikakotini, i-bamboo pulp, njll., kanti amanye amanikiniki azokwengezwa kulabo abanamapulangwe ubuciko obumpofu.Ngakho-ke, iphepha lesikhwama sephepha Ikhwalithi yephepha ayinqunyelwe futhi inokuguquguquka okukhulu.Ngesikhathi esifanayo, isikhwama sephepha sephepha sinamandla angcono wemishini, ngakho-ke ngokuvamile sisetshenziswa njengesikhwama sokupakisha, ikakhulukazi ukupakisha usimende, umanyolo, njll. Ngaphezu kwalokho, manje, ukupakishwa kwemikhiqizo eminingi kudinga ukungena komoya, ngakho-ke ukungena komoya. yephepha lesikhwama sephepha nalo lihle kakhulu.
Izinhlobo zephepha le-kraft ziningi kakhulu, ezingahlukaniswa nezici zombala, ukusetshenziswa kanye nezinto zokusetshenziswa.Ngaphezu kwalokho, amandla ephepha le-kraft likhulu, okungenye yezimpawu ezibaluleke kakhulu ezihlukanisa namanye amaphepha.Ngesikhathi esifanayo, i-kraft paper inamandla kakhulu futhi ingasetshenziswa ukupakisha imikhiqizo eminingi.Ngokwamabanga, iphepha le-kraft lingahlukaniswa ngamabanga amathathu: U, A no-B3.Ngaphezu kwalokho, imikhiqizo ehlukene inezidingo ezahlukene zekhwalithi.Ngesikhathi esifanayo, ikhwalithi ehlukene isho izindleko ezihlukene, ngakho izinkampani zidinga ukuzikhethela.Ngaphezu kwalokho, izikhwama zephepha ezenziwe nge-kraft paper ngokuvamile ziyizikhwama zephepha ezincane, futhi ubukhulu bephepha lesikhwama sephepha abuqinisekile.
Ngamafuphi, isiphakamiso se-plastic restriction order siye sakhuthaza ukuthuthukiswa kwephepha le-kraft, futhi manje abantu bathenga izikhwama zephepha ze-kraft, ezihambisana nemvelo futhi zingasetshenziswa isikhathi eside, okwenza umnikelo othile ekuvikelweni kwezinsiza nokuvikelwa kwemvelo.Ngakho-ke, ukusetshenziswa kwezikhwama zephepha ze-kraft kukhuthazwa.Izikhwama zephepha ze-Kraft ziqinile, zihlala isikhathi eside, zinhle futhi zinobungani bemvelo.
