Ngokuphunyezwa "kokuvalwa kweplastiki" kunye nokuphucula ulwazi lomntu wonke malunga nokukhuselwa kwendalo, izinga lokusetyenziswa kweengxowa zeplastiki liye lancitshiswa kakhulu, kwaye wonke umntu uqalise ukusebenzisa izikhwama zokusingqongileyo okanye izikhwama zephepha.Njengoko sonke sisazi, iphepha sisixhobo esinokuphinda sisetyenziswe kwakhona.Izinto eziluhlaza zokwenza iphepha ikakhulu yimicu yezityalo.Ukongeza kwizinto ezintathu eziphambili ze-cellulose, i-hemicellulose kunye ne-lignin, kukho ezinye iinqununu ezinomxholo omncinci.Ezifana ne-resin, uthuthu, njl. Makhe sixoxe ngomahluko phakathi kwephepha lebhegi yephepha kunye nephepha le-kraft.

Okokuqala, inkqubo yokuvelisa iphepha lesikhwama sephepha kunye nephepha le-kraft lifana kakhulu.Iphepha lesaka liveliswa kusetyenziswa umsonto weplanga ukusuka kwi-softwood kunye ne-kraft pulp.Nangona kunjalo, umgangatho wephepha lebhegi yephepha ngokubanzi ungaphantsi kwephepha le-kraft, kuba, ukuze kugcinwe iindleko zemveliso, amanye amashishini aya kongeza i-pulp ye-cotton stalk, i-bamboo pulp, njl. umsebenzi wobugcisa obuthathaka.Ngoko ke, iphepha lesikhwama sephepha Umgangatho wephepha awulungiswanga kwaye unoguquko olukhulu.Kwangaxeshanye, ibhegi yephepha inamandla angcono koomatshini, ngoko idla ngokusetyenziswa njengengxowa yokupakisha, ikakhulu ukupakisha isamente, izichumisi, njl njl. Ukongeza, ngoku, ukupakishwa kweemveliso ezininzi kufuna ukunyanzeliswa komoya, ngoko ukunyanzeliswa komoya. yephepha bag paper kwakhona kakuhle noko.

Iindidi zephepha le-kraft zininzi kakhulu, ezinokuhlukaniswa kwiinkalo zombala, ukusetyenziswa kunye nezinto eziluhlaza.Ukongezelela, amandla ephepha le-kraft likhulu kakhulu, enye yezona mpawu zibalulekileyo ezizahlula kwamanye amaphepha.Ngelo xesha, iphepha le-kraft linamandla kakhulu kwaye lingasetyenziselwa ukupakisha iimveliso ezininzi.Ngokwamabanga, iphepha le-kraft linokohlulwa libe ngamabanga amathathu: U, A no B3.Ukongeza, iimveliso ezahlukeneyo zineemfuno ezahlukeneyo zomgangatho.Ngelo xesha, umgangatho ohlukeneyo uthetha iindleko ezahlukeneyo, ngoko ke iinkampani kufuneka zizenzele ukhetho.Ukongeza, iibhegi zephepha ezenziwe nge-kraft paper zidla ngokuba ziingxowa ezincinci zephepha, kwaye ubungakanani bephepha lebhegi yephepha abuqinisekanga.

Ngamafutshane, isiphakamiso somyalelo wokuthintelwa kweplastiki siye sakhuthaza ukuphuhliswa kwephepha le-kraft, kwaye ngoku abantu bathenga izikhwama zephepha ze-kraft, ezihambelana nokusingqongileyo kwaye zingasetyenziselwa ixesha elide, ukwenza igalelo elithile kwizibonelelo kunye nokukhuselwa kwendalo.Ngoko ke, ukusetyenziswa kweengxowa zephepha ze-kraft kukhuthazwa.Iingxowa zamaphepha e-Kraft zinamandla, zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.
