Brown paper bag
Kraft paper bag igaba rekurongedza rakagadzirwa nezvinhu zvakasanganiswa kana pepa re kraft rakachena.Haina-chepfu, haina kuravira, isingasvibise, yakaderera-kabhoni uye inoshamwaridzana nenharaunda.Inosangana nemitemo yenyika yekuchengetedza zvakatipoteredza.Iine simba guru uye yakakwirira yekuchengetedzwa kwezvakatipoteredza.Parizvino ndeimwe yeanonyanya kufarirwa zvakatipoteredza kurongedza zvinhu munyika.Kraft mapepa mabhegi anogadzirwa nehuni pulp bepa sechinhu chepasi.Iwo mavara akakamurwa kuita chena kraft bepa uye yero kraft bepa.Iro bepa rinogona kuputirwa nechidimbu chePP zvinhu kuita basa rekusapinda mvura.Simba rebhegi rinogona kugadzirwa kubva pa1 kusvika ku6 layers zvinoenderana nezvinodiwa nevatengi., Kudhinda nekugadzira mabhegi zvakabatanidzwa.Nzira dzekuvhura uye dzekumashure dzakakamurwa kuita chisimbiso chekupisa, kuvhara mapepa uye kuisa pasi.
The drawing breaking force of woven bag chinongedzo mukusimba kwebhegi rakarukwa.Iyo nzira yekudzora iyo yekudhirowa kutyora simba ndeyekudzora chikamu chezvakagadzirwa, kutonhora kuumbwa kwe diaphragm uye kudhirowa kusimba kwesimba.
Nzira yekugadzira inoenderana nenharaunda uye zvinhu.Iyo filler ndechimwe chezvikamu zvikuru zveiyo raw material proportion, iyo inogona kuvandudza hunhu hwebhurashi uye kuderedza mutengo.Kana simba remagetsi revhavha yemagetsi richiwedzera, simba rekusimba rebhurashi richaderera zvishoma nezvishoma.Izvi zvinodaro nekuti chikamu chikuru chekuzadza masterbatch icalcium carbonate, iyo isina tension, Yakapararira mugomba re polyolefin polymer chain, hapana pesvedzero huru pakudhirowa kusimba kwekusimba, kuitira kuvandudza kuomarara kwekudhirowa.Kana huwandu hwekuwedzera hwadarika 20% - 25%, iyo masterbatch yekuchaja ichabata chinzvimbo chepolymer cheni uye ichitadzisa kutenderera kwepolymer, kuitira kuti cheni yepolymer isakwanise kukwidziridzwa pamwe chete neiyo longitudinal yekunze simba.
